Every so often I find that my preview thumbnails through my Mac finder disappear. They don’t disappear entirely, they just stop displaying the preview of the file and show only the generic jpeg icon. It’s a fairly bothersome problem, especially when so much of my work is visual. Fortunately, there’s an easy fix for this, however the fix isn’t always easy to locate when searching the web for answers. So, I thought I’d share it here for you (and for me the next time I need it.)

Note: You may see some previews and not others. if it seems that your Photoshop file preview thumbnails are fine, this could be because Photoshop saves a preview intentionally where as other applications are showing previews differently. https://herbalpotent.weebly.com/wemo-app-displaying-mac-address-incorrectly.html.
- If your Mac struggles to juggle multiple apps, lessen its load by closing apps you aren't using instead of leaving them running in the background. No laps, no sun.
- Dec 13, 2018 I have quite a lot of new files on my desktop computer that have not synced recently to Dropbox. The folders are checked in Settings and as far as I can tell should be syncing. But the names I give most of my data files end with a date in the format YYYY-MM-DD.
May 22, 2017 So now when I log into my account, it lets me open any applications, so I open up say, safari and mail. Then after working on those apps for like 5 minutes, I can't open any other applications, like they just bounce once then won't open. And then, if I close safari or mail, then they won't reopen until I log out then in again.
2 other things to try to fix missing file preview thumbnails:
- Make sure “Show preview” options is selected. If the problem is only affecting a specific folder, look at your folder’s “View Options” (finder > view > show view options) then select “show icon preview. Close the options window. This problem could be due to a corruption in the “.DS_Store” file that contains these settings
- Change the default application associate with your file/s. To render certain file types, the Finder uses “Preview” by default. If you have changed to a third-party application, it is possible the switch is causing problems with your previews. You can fix this by selecting one of your mis-displaying files and choosing the Preview application as the default handler.
- Right click the file
- Get info
- Under “open with” choose the application “Preview”
- Optionally you can then choose “change all” – however I wouldn’t recommend this unless you’re certain you’d like all similar files to open with Preview. Otherwise you’ll end up with another bothersome problem. everythin opening in Preview when you’d rather it open elsewhere.
If your Mac goes to sleep unexpectedly
Make sure that Energy Saver is set up the way you want: choose Apple () menu > System Preferences, then click Energy Saver. Adjust one or more of the following controls to affect when your Mac goes to sleep. Some of these controls might not be available on your Mac.
- 'Turn display off after' slider
- 'Display sleep' slider
- 'Computer sleep' slider
If a slider is set to 'Never,' sleep is disabled for that feature. - Schedule button
Make sure that you aren't putting your Mac to sleep accidentally:
- Pressing the power button can put your Mac to sleep.
- Moving your mouse pointer to a hot corner can put your Mac to sleep, depending on your Mission Control settings. Choose Apple menu > System Preferences, then click Mission Control. Click the Hot Corners button, then see if any of the corners are set to 'Put Display to Sleep.'

If your Mac doesn't go to sleep when you expect
Check your Energy Saver settings as described above, and be aware that your Mac won't automatically go to sleep unless it's inactive:
- The same network activities that can wake your Mac can also keep your Mac from sleeping.
- Any app or other process that's running on your Mac could also be keeping your Mac awake. Check the Energy Saver pane of Activity Monitor to identify apps that need your Mac to be awake. If 'Yes' appears in the Preventing Sleep column for an app, your Mac won't automatically sleep while the app is running. Other apps prevent sleep only when doing certain things, such playing music or video, printing, or downloading files.
If you started from macOS Recovery on a Mac notebook, automatic sleep is disabled as long as the Mac is using AC power.

If the previous steps don't work
These additional steps may help identify or resolve the issue:
- Reset the SMC.
- Reset NVRAM.
- Disconnect external devices other than your Apple keyboard, mouse, and display. If that resolves the issue, gradually reconnect your devices, testing each time, until you find the device that is interfering with sleep. Then check the documentation that came with the device, or contact the device manufacturer.
- Start up in Safe Mode to see if the issue is related to non-Apple startup items, login items, or kernel extensions.
- Try to isolate the issue by using another user account.
If you still see the issue, contact Apple Support.
