When I drag and drop rhino (3dm) file into rhino (latest rhino 8 release, mac) and press cancel, file still opens.

Thank you for your report. I couldn’t reproduce this issue in Rhino 8.35 Mac. I’ve sent the download link via DM, so pls feel free to test it when you get a chance. Thanks!

Just tested on 8.35
Still happens..

Could you please reset Rhino for Mac to factory settings using the Reset command, and then see if the issue persists? Thank you.

It is the first time i am resetting rhino to defaults. And what i did not expect, is all my gh user objects being deleted one by one, without being able to do anyhting. Is there any chance i can restore them?..
It did not give any warning, i had over a hundred user objects

I found backup folder.
‘/Users/user/Library/Application Support/McNeel/Rhinoceros/8.0backup 2026-08-06-10-02-00/Plug-ins/Grasshopper (b45a29b1-4343-4035-989e-044e8580d9cf)’

Thank god

Full reset did not fix that for me, cancel still does not do anything

After testing further, I found that I can reproduce this issue on my MacBook Air as well. I have filed a YT with our development engineers. Thank you again.
