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.
