Hello!
I recently updated my Mac (M2) to Sequoia 15.3.2, and I have had a specific issue in ChimeraX since then (though I cannot be 100% positive the two things are linked). 

Basically - whenever I try to save (anything) in ChimeraX, the application stops responding and I have to quit it. 

I downloaded the newest version 1.9 of ChimeraX as well as the daily build version - but this problem persists.

I read about issues with the graphics driver - but these seem to be limited to Intel chips...

Hoping you might have some insight as to why this is occurring, thank you!!!

Sincerely,
Juliet
