Image thumbnails not displaying in finder since updating to sequoia on my m1 MacBook pro
MacBook Pro 16″, macOS 15.0
The issue of missing icon previews began in Ventura, but there was a plist workaround, which offered a temporary fix. However, this workaround was removed in Sonoma, and it appears they have doubled-down in Sequoia. This change significantly impacts my workflow as a long-time Mac designer. They must really want to get rid of us. If any Mac engineers are reading this, unless you want a mass-exodus... DO BETTER!
I also noticed the icon resizing workaround. BTW, Automator has a built-in Action to change the icon size in Folder Views (see below). This can be used in an Automator workflow to change multiple (or even all) folders.

Interesting. For myself, it's only PNG files that have a generic thumbnail image, whether they're on my local hard drive or on an external drive.
Don't do this with a PSD file, it will merge all the layers. Luckily I have a backup of the file.
NO, I'm running 15.3.2 and the problem is still here !!!!!
Reported. But not holding my breath until Apple resolve the problem.
Not fixed for me. And I have also reported it via the Official Apple bug report page.
Upgraded to Sequoia 15.4 and no change. Thumbnails still not showing. Tried qlmanage -r but no luck with thaty either.
Update : the problem also disappears when the thumbnail icon size is 192x192...
Thanks for your interest and willingness to help.
Finder wasn't displaying thumbnails anywhere, not in any folder. I chatted with Apple support and the theory was the new system hadn't fully indexed the drive. I'm a photographer and have 8 thousand images on my hard drive, some of them quite large. I ran the update to Sequoia iOS 15.0 late in the evening, (foolishly without running a backup first), and gave it a couple of hours before logging off and putting it to sleep. The thinking was it didn't have enough time to index the drive. Seems like that might be the case. It's still slow in some folders, and has been, especially reading camera memory cards. But I'm on the other side of the issue now.
Separate issue, the integration between Apple devices resulted in a weird outcome when I got a call on my iPhone at the same time as I rebooted my MacBook and I lost the call. Not likely to happen very often, but still.
Same here - jpegs and pngs. What I've tried is opening the image in Photoshop and then saving it as a copy. The new version shows the preview icon and then I delete the one that doesn't. It's not ideal but it seems to work and all of the metadata is preserved.
I doubt it is as much as Apple blocking third-party Quick Look code as the software may not have been recompiled to work with the current operating system and any Apple Frameworks that may have changed since the third-party plug-in was originally released. That is on the developer, not Apple.
I used to have a Markdown QL engine that was written several years ago that has not been updated or worked since macOS Big Sur because the original developer never stayed engaged with keeping it current.
In that Finder Window that you just provided a screenshot, press cmd+J to open the Show View Options panel. Is the Show icon preview selected, and if not, by selecting it do the generic icons change to their respective image?
When those PNGs were produced, was there an option to include an icon image that may have been overlooked?
Indexing is definitely an issue with Sequoia. Since 15.1, it’s better, but there are still folders at times in which thumbnails do not show, just the image icons. Also, I can’t airdrop files anymore to my wife’s older MacBook, which I was able to do without issue before Sequoia. When I try, it responds with a failure message.
Since the update to Sequoia 15.1, I'm getting thumbnails for my Canon raw files .CR2, TIFF files and JPEGs, BUT NOT my .DNG files, which are ironically produced by my iPhone 15 Pro Max and are displayed as thumbnails in Photos.
Immediately after updating from 15.01 to 15.1, the battery on my Apple M1 MacBook Pro drained much faster than previously, but that seems to have slowed down. The launch-at-startup antivirus comes up almost immediately when logging in, which is also a change. It came up much slower before the update to 15.1.
So there's been progress with this issue, but there's still a ways to go.
Unfortunately not. I am updated and it's not fixed. In fact, I have new images that are solid white thumbnails now. If I click on the image and have the preview sidebar open it shows the image in the sidebar, but not the thumb.
Most of them with issues (if not all of them) are on the local HDD and not on external drives. So it's definitely a localized system issue.
