This seems to happen periodically with new MacOS releases. Note that the Quicklook preview does work, just not the icon preview.

Yes, I do have the same exact issue!!
Restart did nothing.
Any help?
i can confirm that having upgraded to the monster tree os recently, i like it actually like that, the thumbnails where crap anyway. unfortunately the file size still is the same exorbitant for almost zero geometry. in windows you get to store them in the 100kb range, while on mac these buggers need 5 mb. i was told that was the thumbnail being produced that needs so much space, i argued that not even a super highrest image if compressed acordingly would need such a large file size. and now after these fail finally the prove is there that the large file has zero to do with thumbnails… i am afraid developers have no clue themselves why that is so…
also please dont fix it, there are so many other things which make rhino unusable which still dont work which need much rather attention.
The same issue is also bugging me, but I am still on Rhino 7.
It would be great if this version could get this little fix, too.
I am also using the Affinity suite, and thumbnails behave similarly (here, the Quick Look preview is not working with Affinity anymore). I also find that this problem with the new macOS might be linked to some new API or something that Apple changed in system directories.

This is still broken and needs fixin’.

Thanks, Mary. I had some time yesterday and tried reinstalling MacOS 15.1. Unfortunately, my Rhino thumbnails and the Quicklook previews are still not showing up. May just need to wait for Apple to fix this. Grumble.
(Edit: typed 18.1 instead of 15.1)
I’m just following this I have the same issue for EVERY app that I use. That includes rhino 7
Sequoia 15.1
Mac mini
I use the thumbnails in finder pretty extensively to distinguish between iterative saves on complex projects, so this issue has me feeling pretty hamstrung. I happened across some info HERE and HERE that may be of some use in solving the problem. Bottom line: this is the result of a change in how Apple handles the generation of thumbnails and previews, but it is the developers’ responsibility to implement the changes in their code - which should have happened for Catalina way back in 2019.

Great job with your research!
As it stands, we users still using Rhino 7 deserve an update on this. It’s quite annoying; I returned to check if there has been any response from the developers yet.
Any news anyone?
Hi Miroslav -
The issue report is public:
RH-84357 Mac on Sequoia 15.0.1 Missing Thumbnails
This is currently on the Rhino 9 list of things to look at. So far, nothing that the developer has found points to this being caused by code in Rhino.

Thank you for your reply, and yes, Apple changed something, the problem was present in other apps as well, however to this day every app with this issue has been updated and now Quick Look is working as before. Rhino remains the only app without fixing or I should say n aupdate the app to be fully compatible with the new macOS.
I know I am on a version 7, I am not asking for a new features, just for a fix for the issue and compatibility preservation until I upgrade to a new version of Rhino.

I don’t know if this information helps at all, but ever since I bought R8 (which was when it came out), in addition to the thumbnail issue, the preview when the file opens is stuck.
New files don’t show a preview, and one old file shows the preview from a very early iteration of the model.
(By ‘preview’, I mean the splash screen as the file is loading.)
I’m on macOS Sequoia 15.3.
