Hi everyone,
I recently updated to MacOS Tahoe,
Since then I encountered several issues with Chimera, ChmieraX and python.
I installed and removed and reinstalled the apps but I still get the same error.
For chimera I get this error:

FOr ChimeraX, when I try to open a session, it complains that the session was created with another version of python. I opened that session successfully several times before to the update of MacOS and I have never seen this error before.
Failed opening file /Users/x/x/x/x/x/x/x/x.pyc:
Python code was compiled for a different version of Python
Can you please help me fix this?
Best Regards,
Othman
