Enable Image Thumbnail Icons in Mac Finder

Method 1 – Using the Mac Finder to Enable Image Thumbnails

The default display of the Mac Finder icon in previous versions of OS X was just a simple icon, not the actual thumbnail image. However, image thumbnails are enabled by default in newer versions of OS X. Follow the below-mentioned steps to turn it on or off:

Open the Finder on your Mac and press Command + J or go to Show View Options from the View menu.

In the View Options section, check the ‘Show Icon Preview’ box.

Then, close the View Options panel, and look for the thumbnails for each image.

(Note: If one of your folders contains a large number of images, opening the folder may take a long time because each image requires a thumbnail to be generated.)

Method 2 – Regenerate Finder PLIST file

In the Finder on your Mac, press Shift + Command + G

Next, look for and delete com.apple.Finder.plist.

Now, right-click on the Finder icon in the Dock and choose Relaunch from the pop-up menu.

If Step 3 doesn’t seem to be working, try this:

Hold down the Option key.

Right-click or control-click Finder in your Dock while holding down the Option key.

You can now choose the Relaunch option. If Relaunch doesn’t appear in the pop-up menu, make sure you’re holding the Option key while right-clicking Finder.

Method 3 – Via Activity Monitor

If you are unable to perform the above-mentioned steps, follow the steps :–

At first, go to the Applications and then navigate Utilities

Now, open Activity Monitor on your Mac.

Then, select View and then click on All Processes from Activity Monitor’s menu bar.

Type com.apple.quicklook.ThumbnailsAgent into the search field in the top-right corner of the Activity Monitor window and press Enter.

Select the process from the list, then click the Stop icon in the taskbar

After that, in the menu bar, select Force Quit by clicking the Apple symbol

In the Force Quit Applications list, select Finder and then click the Relaunch button.

After relaunching Finder, your icon thumbnail previews should be restored in Finder windows and on your desktop.
