Want to clear and disable Significant Locations data stored on your Mac? For some quick background, your Mac will attempt to determine what locations are significant to you in order to provide you with location related information for Maps, Photos, Calendars, and with other apps too. These stored places are referred to as “Significant Locations” and can be very helpful for traffic and directions predictions, along with other location related assistance.
Some Mac users may prefer to disable the Significant Locations feature and clear any existing Significant Locations data from the Mac, and this tutorial will show you how to do that.
How to Clear & Disable Significant Locations on Mac
Go to the Apple menu and go to “System Preferences” and then go to the “Security & Privacy” preference panel
Choose the “Privacy” tab and then choose “Location Services”, then click the lock icon in the corner to authenticate and unlock the ability to make changes
Scroll down to find ‘System Services’ and click on “Details”
Locate the ‘Significant Locations’ settings and click on “Details” to see a list of any and all stored significant location data on the Mac
To clear all Significant Locations history, click on the “Clear History” button
Confirm that you want to clear significant locations from the Mac as well as from all other devices signed into the same Apple ID (for example, any other Macs, iPhones, iPads, etc)
Uncheck the box for “Significant Locations” then click on “Done” and exit out of System Preferences as usual
While you’re in the Location Services section of Mac system preferences, you might also decide to manage and control which apps can use location data on Mac. It can also be helpful to show the Location Usage icon in the Mac menu bar to be able to easily determine what an app or service is using your computers location data. If you never use any location specific data or services from the computer whatsoever, you can also completely disable all Location Services on Mac, but that is not recommended for most people.
It’s important to note that Apple says that Significant Locations are encrypted and cannot be read by Apple, so if you’re worried about the feature for any reason related to that, you probably shouldn’t be. Nonetheless there are many privacy and security conscious users out there who would rather minimize their location usage footprint, or even not have any type of location data kept or stored at all, regardless of its purpose.
As with all settings on the Mac, you can always reverse this decision and re-enable Significant Locations on the Mac again. Note that re-enabling significant locations will not bring back any cleared prior significant location data, however.
At some point in time you may have installed the popular Malwarebytes tool on a Mac to scan for malware, spyware, ransomware, junkware, and other garbage threats on a Mac, but at some point you may decide you want to uninstall Malwarebytes from the Mac and remove the utility from a computer.
Whether you’re using the free or paid version of Malwarebytes you’ll find that uninstalling it is fairly easy. We’ll cover two methods to remove Malwarebytes from a Mac.
How to Uninstall Malwarebytes from Mac OS the Easy Way
The simplest way to uninstall Malwarebytes from a Mac is to use the apps built-in uninstaller:
Open the Malwarebytes app on the Mac, found in the /Applications folder
Pull down the “Help” menu and choose “Uninstall Malwarebytes”
Choose “Yes” when asked if you want to completely remove Malwarebytes from the Mac
Authenticate with the admin password to uninstall Malwarebytes
How to Remove & Uninstall Malwarebytes by Script (if the Application is Missing, Doesn’t Work, etc)
If for some reason the above easy approach to uninstalling Malwarebytes does not work, or perhaps you already deleted the primary Malwarebytes application and so you no longer have the capability to use the built-in uninstaller function, another is available using a free removal script from Malwarebytes. Here’s how that works:
Launch the “Uninstall MWB” tool from the Downloads folder
Choose “Yes” when asked if you wish to remove all components of Malwarebytes from the Mac
This is the preferred method to remove Malwarebytes from a Mac. It’s easy and it’s relatively fast, and it should remove every component of Malwarebytes from the computer without having to do anything else.
Nonetheless there are other options which may be necessary if the primary application has already been removed, but other Malwarebytes components remain on the system.
When finished, Malwarebytes will have been deleted and all components uninstalled from the Mac.
Many of the components of the app remained which is often the case when simply dragging an app to the Trash does not uninstall everything related to the application. If you’re aiming to remove Malwarebytes from a Mac you can use either approach, but if the application is missing with the built-in uninstall tool then using the uninstaller script will still remove remaining Malwarebytes components from the Mac.
These uninstall methods should work on any semi-modern Mac running any modern version of Mac OS or Mac OS X, though the uninstaller script is valid for 10.10 and later only.
Technically speaking you could also manually remove Malwarebytes but that process is much more cumbersome than simply using the uninstaller tool offered in the application itself, or the uninstaller script available as a download from Malwarebytes. If you do want to manually remove the Malwarebytes app, you’ll be digging around in various user and system folders and searching system files for a variety of plists, extensions, and other components of the app, and other stuff. That’s really only appropriate for very advanced users, and there is little purpose to do so when there are easier uninstall methods.
To be clear, this is not a suggestion, this is simply a tutorial demonstrating how to uninstall Malwarebytes from MacOS. If you use Malwarebytes and find it useful, there’s no reason to stop using it or to remove it from a Mac. And remember that if you remove it because you’re finished using it for now, you can always install Malwarebytes again later if you want to.
As we mentioned before, Malwarebytes is a popular Mac utility and even the free download version will work for scanning and removing malware and junkware from a Mac, but whether or not you use it, or want to remove it, is entirely up to you. It’s generally well regarded and doesn’t carry some of the baggage (and bad headlines) that some other scanning and cleaning utilities out there, so if you’re interested in an malware scanner and removal tool on the Mac it’s a good choice even at the free level. If you are going to install a malware removal tool on the Mac, it’s best to pick just one and don’t overlap them to avoid any issues.
Malwarebytes for Mac is a popular and respected anti-malware tool for Mac that can help to clear a Mac of malware, ransomware, and viruses. While users can follow some simple tips to protect a Mac from viruses and trojans, and MacOS is fairly secure as-is from malware, junk ware, and adware, many Mac users often ask how they can scan their Mac for adware or for viruses. For those who have some concerns about malware on a Mac, using the Malwarebytes app to scan and clear a Mac can offer some additional peace of mind.
This article will show you how to install Malwarebytes on a Mac, and how to use the free version to scan and clean a Mac of any threats.
Note this tutorial will use the free level of the Malwarebytes app, which has the ability to scan and clean any discovered infections from a Mac. If you feel like you want or need enhanced security to proactively protect a Mac from further threats, then you’re welcome to try the paid version on your own.
How to Install Malwarebytes Malware Scanner on Mac to Clean Malware, Viruses, Adware, etc
Go to the user Downloads folder and open the “Malwarebytes” package installer
At the Malwarebytes installer screen, choose Continue and read through the release notes and license terms
Select the drive you wish to install Malwarebytes onto, this is likely the primary boot drive named “Macintosh HD”
Authenticate the installer to let Malwarebytes complete installation
In a moment you’ll be presented with a screen asking where you’re installing Malwarebytes, either Personal / Home or Work
At the next screen, choose “No thanks, I just want to scan” (or sign up for the 14 day free trial if you want to try out the full paid version)
At the Malwarebytes application screen, choose “Scan” to scan the Mac right away for any threats
If any threats or junk is found, Malwarebytes will report it to you on the next screen, otherwise you’ll see a screen saying the Mac is clean and clear
As mentioned before, we’re using the free version here to simply scan and clean a Mac (assuming any malware, bad junk, or unwanted stuff is found), but you’re certainly free to try out the 14 day full protection trial, or sign-up for the complete paid service and unlock the other features of the Malwarebytes app.
If you’re satisfied with the Mac being cleaned and scanned, you can quickly uninstall Malwarebytes from the Mac just by opening the app and pulling down the “Help” menu and choosing to “Uninstall Malwarebytes” and following the steps on screen.
To be perfectly clear, this is not any particular recommendation and we do not have any relationship with Malwarebytes, we just use the tool ourselves to scan Macs for scanning for junkware if the need arises either on our own hardware or someone elses (even back when the app was called AdwareMedic).
“how can I scan my Mac for viruses and malware?” and “how can I clean my Mac from adware or a virus?”,
so these questions are common. Generally speaking, a well secured Mac that has regularly updated system software and apps, and some savviness from the user like not downloading sketchy stuff from untrustworthy dubious websites and not installing browser plugins – is enough to prevent Macs from finding any malware, junkware, adware, ransomeware, or any other nefarious stuff on their Mac, but nonetheless infections can still happen.
Do you want to turn off the screenshot thumbnails that show up on the Mac screen? You may have noticed that if you take a screenshot on Mac a little screenshot thumbnail preview pops up in the bottom right corner of the display and floats there for a few seconds. You can interact with that little thumbnail to quickly markup a screenshot, but showing those screenshot thumbnails also appears too slow down how long it takes for the actual screen shot file to generate and be available to the file system.
If you want to disable the screenshot thumbnail preview in Mac OS, this article will show you how to do that.
How to Turn Off Screenshot Preview Thumbnails on Mac
From the Finder of Mac OS, go to the /Applications/ folder and then to /Utilities/ and open the “Screenshot.app” application
Click on the “Options” menu in the screenshot toolbar
Uncheck the option for “Show Floating Thumbnail” to disable the screenshot preview
Exit out of Screenshot app when finished
With ‘Show Floating Thumbnail’ disabled, the screenshot previews will no longer appear, and the screenshot that has been snapped will be created and appear almost instantly in the Finder, much like in earlier MacOS versions.
For those who are wondering, the Mac ‘Screenshot’ application takes the place of the “Grab” app in modern MacOS versions, and it has other handy features too that make it easy to change some screenshot options that used to require the Terminal and defaults commands. For example you no longer have to use a defaults write command to change the screenshot file save location, and you can also set a timer and mouse pointer option for screenshots too just like you could in the Grab app. You will still need to use a defaults write command to change the screenshot image file format or screenshot file names however.
How to Re-Enable Screenshot Thumbnail Previews on Mac
Open the “Screenshot.app” application from Spotlight or the Applications/Utilities/ folder
Click the “Options” menu and check the option for “Show Floating Thumbnail” to enable the screenshot preview
Exit out of Screenshot app
With the floating thumbnail option re-enabled, screenshot previews will show up again, and there will be a delay before screenshot files appear in the Finder and to the file system again.
You may have noticed a similar screenshot preview on iPhone and iPad as well, but in the iOS / iPadOS side of things there is currently no method to disable that screenshot preview, as this option remains only on the Mac. Instead on the iPhone and iPad you can simply swipe or push the thumbnail aside to dismiss it, a trick that also works to dismiss the screenshot floating preview on Mac as well.
Safari on the Mac can resume stopped downloads and restart failed downloads rather easily. For example, if you were downloading Xcode from Apple but your internet connection was interrupted and the download stopped, you can resume the download where it left off rather than restart the entire download over again. This is a great way to restart and resume incomplete downloads, regardless of the reason the file download failed, was interrupted or otherwise halted, and it’s available in the Safari download manager on Mac OS.
How to Resume Incomplete Downloads in Safari on Mac
From Safari on the Mac, click the Downloads button in the Safari toolbar, it looks like an arrow pointing downwards
Locate the stopped, stalled, or failed download, then click the orange circular arrow button to attempt to restart the download
The file should resume downloading where it was otherwise interrupted
Once the file, archive, image, or whatever else has completed downloading, it will appear in the Downloads folder on the Mac.
Note that Safari defaults to downloading things into the user Downloads folder, but you change the Safari download location on Mac if desired. Thus if you had previously changed the download location, you’d need to find the item there instead.
If you do need to start the download over from scratch, often an easy way to do that is to copy the downloaded files original direct download URL from Safari and simply paste that address back into the URL bar. Note that approach doesn’t always work with randomly generated CDN address downloads however. Similarly, you can find out where a file was downloaded from on the Mac by using Get Info in the Finder on the file, even if the file is only partially downloaded and incomplete.
Some other web browsers also support file download resuming as well, including Chrome, though how you go about resuming downloads in Chrome is different than what is discussed here in Safari.
You may have noticed that sometimes you can not power on and boot a MacBook Pro when it doesn’t have a battery installed. Let’s say you had to remove the battery of an older MacBook Pro because it was swelling, or the battery failed for some other reason, but when you go to power on the MacBook Pro, nothing happens. (To be clear, this article is aimed at older MacBook Pro model years, like a 2006, 2007, 2008, 2009, 2010, 2011, back when replacing a battery, hard disk, RAM, was all fairly easy to do by opening the bottom case).
In this situation, if a battery is removed or totally dead and you attempt to start the MacBook Pro, nothing happens – there is no sound, no system boot, no startup chime, nothing. It turns out that some model year MacBook Pro computers will not boot with a simple power button press after the battery has been physically removed or disconnected.
Of course if you happen to have a replacement battery then you can typically just replace the missing battery with a working battery and the MacBook Pro will boot, but that is not always an option. So let’s discuss how to boot an older MacBook Pro when there is no battery present at all.
How to Boot MacBook Pro with No Battery Installed
We are assuming the MacBook Pro has no battery installed in the computer, meaning there physically is no battery installed. Then, when attempting to boot the Mac or pressing the start button, nothing happens. In this case, you can force the MacBook Pro to boot by following these steps:
Unplug the MagSafe power cable
Hold down the Power button for 10 seconds and continue to hold it down
While still holding the Power button, connect the MagSafe power cable to the MacBook Pro and continue to hold the Power button for another 10 seconds
Release the Power button, then press the Power button as usual to power on the computer and boot the Mac
When the MacBook Pro does boot, the fans will be blasting at full speed for the entire time you are using the Mac (resetting SMC or PRAM does not stop the fans running, only replacing the battery will).
Also it appears that the MacBook Pro will reduce its own clock speed in this situation, thereby reducing performance.
The only way to stop the fans from running at full speed and to return the clock speed to regular performance is to install a new battery into the MacBook Pro.
As some experienced this scenario on an old MacBook Pro 2010 model after removing a swollen battery. Once the battery was removed you can press the power button but nothing happens. However, the above method of disconnecting and reconnecting MagSafe while holding the Power button was successful in starting up the Mac – with fans running at full speed and at reduced clock speed however. Nonetheless, Snow Leopard still runs well!
As you can see in the screenshot below, the “No Battery” indicator is visible, but the MacBook Pro is booted and working.
And indeed, this particular MacBook Pro has no physical battery installed as you can see the internals in this picture:
Powering Up a MacBook Pro After Replacing Battery, Logic Board, Hard Drive, RAM, etc too
Apparently the same aforementioned scenario of the MacBook / MacBook Pro not starting up can also unfold when replacing other internal components on these older model year MacBook Pro (2006, 2007, 2008, 2009, 2010, 2011, etc), including replaced logic boards, internal hard drives, RAM, battery, and perhaps other hardware components too.
With some other internal component replacements, sometimes simply plugging in the MagSafe adapter and holding the power button for 10 seconds is enough to cause the MacBook Pro to start.
Also, Check the Power Adapter Wattage
For what it’s worth, in some scenarios where the battery appears dead but is not actually (ie, the charge is long drained but the battery itself isn’t completely useless yet), then you may be able to successfully boot the MacBook Pro with a proper wattage MagSafe power adapter of 85W. These older model year MacBook Pro computers use 85W power adapters, whereas the MacBook and MacBook Air of the same generation used 60W power adapters. Sometimes simply plugging in the proper higher wattage power adapter will allow the MacBook Pro to boot.
This MagSafe power button pressing solution was found on iFixIt forums and it worked for me, so if you’re in a similar scenario with an older MacBook Pro then try it out yourself. If for some reason the above method does not work, the original forum poster does state the following possible workaround involving moving a RAM module to a different slot (if applicable):
“If that doesn’t work then try to remove one RAM memory [module] and switch places and [repeat] the method”
In my case this juggling of the RAM module was not necessary to boot the MacBook Pro (a 2010 model year) without a battery, but that additional tidbit may be valid to you.
This article is obviously aimed at older MacBook Pro hardware, but it may be relevant to other older MacBook models too, including similar model year (2006, 2007, 2008, 2009, 2010, 2011) MacBook and MacBook Air, and perhaps even some newer MacBook Pro models too. By the way, if you’re rocking an older Mac and want to speed it up, check out these tips.
Of course newer model year MacBook (Pro & Air too) hardware does not have user serviceable batteries and in some cases the battery is glued to the top case, so in those situations the ability to end up in a situation where the computer doesn’t have a battery is much less likely, and any troubleshooting scenario is going to be much more extreme requiring a more thorough hardware repair that is far beyond the scope of this particular article. In those situations, take the Mac to a certified Apple Repair Specialist or an Apple Store instead.
Long live the old Macs! Does this qualify for retro status yet? Probably not… give it a bit longer.
Want to toggle Do Not Disturb mode on the Mac with a keyboard shortcut? You can easily enable a custom keyboard shortcut to turn on or off Do Not Disturb mode in MacOS, and we’ll show you how to set it up.
Do Not Disturb mode on the Mac is one of the best features you can use if you want to focus on a task, and not be distracted by the myriad endless notifications and alerts that pop up on the Mac. Enabling and disabling the feature with a keyboard shortcut offers a quick way to toggle the feature off or on as quick as possible and at any time.
How to Set a Do Not Disturb Keyboard Shortcut on Mac
To be able to toggle Do Not Disturb off or on by keyboard shortcut on Mac, you’ll need to enable a keyboard shortcut for it first. Here’s how to do that:
Go to the Apple menu and select “System Preferences”
Go to “Keyboard” and then choose the “Shortcuts” tab
Select “Mission Control” from the Shortcuts options
Locate “Turn Do Not Disturb On/Off” and make sure that is checked to be enabled
Click directly to the right of “Turn Do Not Disturb On/Off” and then press a keyboard shortcut combination to set as the Do Not Disturb keyboard shortcut
In the example here, the keystroke combination SHIFT FN F10 was set as the keyboard shortcut for enabling and disabling Do Not Disturb mode.
You can set any keyboard shortcut you want for this purpose, just make sure it’s unique and does not overlap with another keystroke combination or feature. Applying modifier keys like Shift, Option, Control, FN can be an easy way to avoid conflict with other keyboard shortcuts on the Mac. Whether FN SHIFT F10 works for your particular situation is going to depend on your individual Mac setup.
How to Toggle Do Not Disturb ON or OFF by Keyboard Shortcut on Mac
Once the keyboard shortcut for toggling Do Not Disturb mode is enabled, you can use it at anytime by pressing the keystroke combination you set in the above steps. In the example here, that would be pressing SHIFT FN F10, so therefore toggling the feature would be as so:
Press SHIFT FN F10 to enable Do Not Disturb mode instantly
Press SHIFT FN F10 to disable Do Not Disturb mode immediately
When Do Not Disturb mode is on, all notifications and alerts will not show up on the Mac, but they will still be contained within the Notification Center.
When Do not Disturb mode is off, all alerts and notifications will come through to the Mac as usual, showing up as pop-up alerts in the upper right corner of the screen.
Do Not Disturb mode is one of the most useful features available on the Mac and on the iOS side of things too, where using Do Not Disturb mode on iPhone and iPad can offer some peace and quiet when you’re on the go as well.
If you find yourself toggling this feature on frequently, you might want to set a schedule for Do Not Disturb on Mac to be automatically on at times of your choosing. And if you don’t like the annoying notifications at all then you can precent all notifications on the Mac by setting Do Not Disturb mode in perpetuity to be always enabled using a scheduling trick, which will make it so your Mac is never harangued by the alerts and notifications from everything under the sun.
If you’re a Mac user who relies on iCloud Drive for data syncing and cloud storage, you might appreciate knowing that you can enable an optional iCloud Status indicator in the Mac Finder.
The iCloud Status indicators in Finder can tell you if a file or folder is only in iCloud, on the local Mac, ineligible for iCloud, waiting to upload, transferring, and more. Note these iCloud Status indicators are different from progress indicators, though you can also check the progress of iCloud file uploads and downloads in Mac OS if desired.
How to Enable iCloud Status Indicator for Mac iCloud Folders
Go to the Mac Finder
Navigate to an iCloud Drive folder, or if you use iCloud Desktop and iCloud Documents to there *
Switch the folder to List View (click the List view button, or go to View menu > As List)
Pull down the “View” menu and choose “View Options”
Check the box for “iCloud Status” to enable the iCloud Status indicator for the iCloud Drive folder
Close out of View Options
Once the iCloud Status view option has been enabled, it will be visible as a column in List view. Like other sort columns, you can move it around as desired.
You can also right click on the file list headers and choose to toggle “iCloud Status” from there, which is quicker than going to View Options preference panel.
Note if you disabled iCloud Desktop and Documents folders on MacOS so that your desktop and documents aren’t uploading into iCloud, then this iCloud status indicator feature won’t be available for those directories, and instead will be limited to iCloud Drive. This is signified by the iCloud Status option being grayed out and unselectable.
With the iCloud Status indicators enabled, anytime you are copying files to iCloud Drive from Mac or moving files to iCloud from Mac OS you will see the indicator change for those files. Likewise if there is other activity within the iCloud folders, that will show with the iCloud status indicator as well.
If you frequently put data into iCloud Drive or an iCloud enabled Documents or Desktop folder, you might want to think about adding iCloud Drive to the Mac Dock for quick access. It can also be helpful to watch upload progress of files and folders that are transferring to iCloud from the Mac.
Want to change the tracking speed of the cursor on a Mac? Maybe you want your mouse to move around on the screen faster? Perhaps you want the Mac trackpad to move the cursor slower?
You can manually change the tracking speed of either a mouse or trackpad connected to a Mac, and you can even have different tracking speeds for a mouse as you do for a trackpad, a handy trick for users who have both input methods in use on their Mac.
How to Change Tracking Speed of Mouse / Trackpad Cursor on Mac
Go to the Apple menu in the upper left corner of the display
Choose “System Preferences”
Select “Trackpad” or “Mouse”, depending on which you have or want to adjust the cursor tracking speed for
For changing Trackpad tracking speed: Under the “Point & Click” section, look for “Tracking speed” and adjust the slider on the scale from “Slow” to “Fast” as preferred, the tracking speed changes immediately so you can test the change right away
For changing Mouse tracking speed: Adjust the “Tracking speed” slider on the scale from “Slow” to “Fast” as desired
Close out of System Preferences when finished
What tracking speed you use is almost entirely a matter of personal preference. Some users really like a fast tracking speed, while others prefer a slow speed. You should try out different settings and see which works best for you. Often you’ll find somewhere in the middle of the tracking speed slider options offers a good compromise.
Remember you can change the tracking speed of the cursor for input devices independently from one another. For example, you could have the internal trackpad of a MacBook Pro set to fast tracking speed, but any connected mouse could have a slow tracking speed, or vice versa. To independently change the cursor speeds of different input devices, just connect each input device to the Mac and then go to the “Mouse” settings and then the “Trackpad” settings and adjust each as needed. (Side note; you can also independently control mouse and trackpad acceleration speeds with a third party tool, but that’s a different topic)
Note a separate preference setting exists so that you can also change the scrolling speed of a mouse or trackpad on the Mac, which applies to either gestures for scrolling or to scroll wheels.
Some related helpful tips may be changing the size of the Mac cursor, and if you notice the cursor randomly getting big when you move the mouse or trackpad suddenly and you don’t like that, then you might want to disable Shake To Find on the Mac.
Need to delete a virtual machine from Parallels or Parallels Desktop Lite? Removing a virtual machine can be necessary when you’re finished using a particular environment, operating system, or VM for any reason, and it’s also common to remove unneeded virtual machines to free up disk space.
Here’s how you can easily delete a virtual machine in Parallels and remove it from the Mac (or Windows PC).
How to Remove Virtual Machines in Parallels & Parallels Desktop Lite
Launch Parallels or Parallels Desktop Lite, but do not start any virtual machine
Select the virtual machine you want to delete from the Control Center (if Parallels launches immediately into a VM, exit the VM and go to the main screen first)
Go to the “File” menu and choose “Remove”, or alternatively right-click on the VM and choose “Remove”
Select “Move to Trash” to delete the virtual machine without saving anything, or choose “Keep Files” to be able to use the VM again in the future if needed
Repeat with other virtual machines you want to delete
Now go to the Finder and empty the Trash as usual (or right-click the Trash icon in the Mac Dock and choose “Empty Trash”)
Emptying the Trash is necessary to actually delete the virtual machine from the Mac and free up disk space on the computer.
It doesn’t matter if you use the File menu or the right-click menu to delete the virtual machine, the steps are the same afterwards.
Note: if you’re deleting a virtual machine from Parallels on Windows, you empty the Recycle Bin instead of the Trash like on the Mac.
Note that if you simply move the virtual machine to the Trash but don’t empty the Trash on the Mac, that VM can be recovered anytime before the Trash is emptied by simply going to the Trash, locating the vm file (usually labeled as the OS with the file extension “.pvm” like ‘Debian Linux.pvm’) and adding that VM file back into Parallels.
Virtual machines offer a powerful way to test out and use other operating systems by running them in an application layer atop an existing operating system, and this capability is not limited to Parallels or Parallels Desktop Lite. You can use virtual machine software like VirtualBox or VMWare for running Windows 10, Windows 8, Windows 7, Windows 2000, NT, 98, 95, 3.11, Windows with older versions of Internet Explorer ranging from IE 7 to IE 9, Ubuntu Linux, ParrotSec Linux, or just about any other Linux distribution, BSD, a variety of versions of Mac OS and Mac OS X including MacOS Mojave and macOS Sierra, BeOS / HaikuOS, and many other operating systems too. And of course you can delete virtual machines from VirtualBox and VMWare too if needed.
