On macOS 11 Big Sur, there is one noticeable difference in behavior between the two. The principal difference between the 3.9.1 and 3.10.0a4 versions I tested with is that the 3.9.1 is linked with Tk 8.6.10 while 3.10.0a4 is linked with the just-released Tk 8.6.11. Now just to make things a bit more complicated - sigh: I also tested with the recent installer for the 3.10.0a4 pre-release.

I believe this entry from summarises my issue best: Other posts online suggested this could be an OS issue I tried upgrading to Monterey but the issue is still present. Unfortunately, I have already checked System Preferences> Privacy settings and I can see Python is granted access to documents. I have seen similar issues online but I am yet to find a solution that works. However, when IDLE is not already open, I get an error message saying “The document could not be opened.IDLE cannot open files in the python script format”.

Hello, whenever I have IDLE open, I can right click a python script in finder and open with IDLE.
