hi, since updating to macos 15.4 are the thumbnails in the preview windows black. this is only the case in column view. if I change the column size, the image appears, but only the marked image. When i click on the next thumbnail it is black again.
if i open the image in quicklook (spacebar), then appears it normal. just in column view is it black.
Mac mini, macOS 15.4
I don't know how soon it will be, Certainly not before Sequoia 15.5.
Feel free to send Apple a bug report.
FWIW, if you are viewing RAW files, there is a known issue with certain cameras that were supported before Sequoia 15.4.
Hi, I have same problem since Sequoia 15.4 update. But with space bar quick view is black pictures all the time. The NEF file comes from Nikon D750. We need sequoia update to fix the issue. thanx
I am not seeing this on my mac.
Does it also occur if you do this is in a new user account on the same mac?
If not, then the issue is restricted to your usual account. You could try deleting Finder preferences:
To delete Finder preferences: 1) In Finder, press Command-Shift-G and paste ~/Library/Preferences/com.apple.finder.plist 2) Drag the file to the trash 3) Press Command-Option-Escape to open the Force Quit window. Select Finder in the list, and click Relaunch.
Me too. Ugh! Quick Look appears broken in 15.4 when trying to access CR2 files. (So much for the old workflow.) Problem persists when testing in a new account. Am still able to view and edit files within Lightroom.
Prior to finding this thread, tried a variety of steps--none of which helped.
Relaunched Finder
Force Quit Finder
Force Quit Quick Look Processes
Cleared Cache
Rebooted
Tested in Safe Mode
you are right, these are NEF data, so Nikon Raw files. I hope there will be a solution to the problem soon from Apple
Thanks Dialabrain, It's also funny that if I resize the window, the thumbnail is visible.
FWIW, You might want to try the free XnView XP
It's certainly possible it will show the RAW thumbnails correctly in Sequoia 15.4.
You're welcome. Whatever the issue is that is introduced in 15.4, it doesn't affect RAW images from all supported cameras.
thank you, i have Adobe Bridge. These works fine too.
You're welcome.
quicklook (preview) thumbnail is black in column view
