Description

Area:
Finder

Summary:

File Previews/Thumbnails are unreliable/not shown on macOS Mojave. It happens on the Dock and on Finder. I think something is crashing iconservices or another process like that.

Steps to Reproduce:

None, just use the Mac as usual.

Expected Results:

Finder/Dock show the previews reliably on file types that support it.

Actual Results:

Finder shows the previews rarely and Dock fails at it most of the time.

Version/Build:

10.14 Beta (18A371a)

Configuration:

Macbook Pro Retina 15-inch w/ Touch Bar, 2017 model

Attached a sysdiagnose of the system while the bug was occurring.

Product Version: 10.14

SatoshiBTC, please elaborate. What are the steps involved?

Also, on a side note, I tried clearing ~/Library/Cache didn't work, tried deleting finder.plist from ~/Library/Preferences and rebuilding it but didn't work.

@rdastartupguy You just need to run 'First Aid' on your boot disk using Disk Utility. This worked for me (without a restart) although it breaks again as soon as a new file is downloaded.

I also tried this plus the usual PRAM / SMC and had no luck. However - The first time I tried zapping the PMC my finder started to work for a brief time and then reverted back to the situation described in this thread.

I tried this with the support but in my Mac sometimes display the thumbnail and another sessions not, my system is unstable.
And I can not find the error yet.
I did the next:
0. Check if the thumbnails display in safe mode. In my case in safe mode was ok.

  1. Remove those task from launching when you boot up your Mac. you’re going to want to remove all those apps in the list.
  2. reset and do the NVRAM/SMC resets.
  3. then test and see if that resolved the issue.

Remove tasks. From laughing: Go to:  > System Preferences > Users & Groups. Select your name on the left, then click on LOGIN ITEMS. Then deactivate all the apps You’ll want to select each app in that list, then hit REMOVE or the minus sign at the bottom. It just removes those task from launching when you boot up your Mac.

#For resetting the NVRAM, we would just want to go through these few steps. 1. Shut down your Mac. 2. Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4. 3. Turn on the computer. 4. Press and hold the Command-Option-P-R keys before the gray screen appears. 5. Hold the keys down until the computer restarts and you hear the startup sound for the second time. 6. Release the keys. Resetting the NVRAM usually resets settings such as Speaker Volume, Screen Resolution, Startup Disk selections, Time Zone information, and a few other settings.

#How to reset the SMC on Mac notebooks 1.Shut down your Mac. 2.Using the built-in keyboard, press Shift-Control-Option on the left side of the keyboard, then press the power button at the same time. Hold these keys and the power button for 10 seconds. 3.If you have a MacBook Pro with Touch ID, the Touch ID button is also the power button. 4.Release all keys. 5.Press the power button again to turn on your Mac.

In the safe mode my thumbails works ok and is very fast, but in normal mode the system is unstable for display the thumbails.

The actual cause of this problem appears to be Sketch.

Removing Sketch (and using the beta version for now: http://sketchapp.com/beta/) solved the problem for me after a reboot.
