Rhino 8 crashing on my 2023 Mac Book Pro running Tahoe (26.5.1)

Elise M. (with help from Elise’s dad).

Hello. I can use some help. Have issues with Rhino 8. It was running fine since we loaded it back in the fall of 2025. But after a recent update to my Mac Book Pro M2, running Mac OS Tahoe, Rhino will not open up any longer. Tried to de-install, then reinstall Rhino, no luck. We do get a crash report which I will attach below.

The crash happens directly after trying to open Rhino,tforced quit, then goes straight to crash report. The trouble started after an Apple upgrade to Tahoe 26.5.1. Then Rhino would not run.

We then downloaded the latest version of Rhino, “rhino_8.32.26160.13002”. After install it locked up again. Tried to clean up the system, throw out prefs, Rhino app, McNeel folder. Then tried again. Nothing.

Here is the error report.

@dan can you help with this issue?

Does Rhino Beta (9) work for you?

Did you install any 3rd party plugins? Datasmith perhaps?

Hi Elise and Ed-

I think this is a known bug with Apple’s ScopedBookmarkAgent. It’s probably snagging you because of the Splash Screen that Rhino shows at startup which shows your recent files list. A quick way to verify this would be to try double-clicking a 3dm file from Finder to launch Rhino - this ought to bypass the Splash Screen and avoid the crash. Try that. I bet it’s that.

If my suspicion is correct, we can probably limp along until Apple fixes this. Then try this:

  1. Quit Rhino (or Force-Quit if it’s stuck).
  2. Launch Activity Monitor (the macOS built-in utility). Search for ScopedBookmarkAgent. Select it and Quit it. It will restart automatically.
  3. Clear Rhino’s macOS recent-files list: In Finder, Go (menu) → Go to Folder… (command+shift+g) and paste in this exact path: ~/Library/Application Support/com.apple.sharedfilelist/com.apple.LSSharedFileList.ApplicationRecentDocuments
  4. Move com.mcneel.rhinoceros.8.sfl3) - the extension might be .sfl2 - to the Trash.
  5. Restart your Mac.
  6. Try launching Rhino as you usually do.

Any better?

No 3rd party plugins installed.

Thanks Dan. I will try those two suggestions today. Thanks everybody.

Also Dan, I did try launching Rhino from a desktop file. No response. Just froze.

Thanks for trying that. That’s a bit confounding.

Please try the second set of steps anyway. I can see from your crash report that the hang is happening when attempting to load that recent files list, so I’d still like to see if clearing that cache helps or not.

Hi Dan.

That worked perfectly! We are back up and running. Thanks again for your clear, concise instructions. Easy to follow and very helpful. Thanks again.

Glad that worked! Did you have an external drive connected now or before? Or perhaps an iCloud Sync’d folder that has changed?

10

Yes. I was using a external drive on this laptop recently/yesterday. Not too sure about a new icloud question. I don’t think so, but not 100% sure.

11

Were any of the 3dm files on that external drive?

12

I do not believe so. I tried to open a desktop file that failed.
