This seems to happen periodically with new MacOS releases. Note that the Quicklook preview does work, just not the icon preview. [Screenshot 2024-09-18 at 8.34.41 AM]

RH-84357 is fixed in Rhino 8 Service Release 17

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.

BUMP< This is still broken and needs fixin’.

This is on the list as RH-84357 Mac on Sequoia 15.0.1 Missing Thumbnails Thanks, -wim

See the fix here: [image] Thumbnails Not Generating Rhino 8 Mac Rhino for Mac Hi @scroggin, Sorry for the issues you are having with your file previews. They are tough and this is what I found out today from our developers. This is what we know: This seems to be related to the Sequoia 15.0.1 update. The thumbnail preview is not the responsibility of anything provided by the Rhino for Mac. Mac OS’s Quicklook generates these. Some of our developers here have also seen the indexing get out of sync. The thumbnails go away for awhile…a restart of the Mac helps and sometim…

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?
