Any MAC OS version at or "above" Catalina can no longer run 32-bit programs.

11.0.1 > 10.15

Well I am running wineskin and I am running a few 32 bit programs. However anything in steam just wont run. Do you think steam will update and allow those to be run again even though 32 bit isnt support by mac osx?

Wine re-packages Windows apps to run on Mac. Native Mac apps must be 64-bit. Steam won't be updating the apps unless the developers do.

so... there's no way to play my 32-bit games anymore? I found that if they were already downloaded to my Mac before the update it functions the same and doesn't have any trouble opening (Undertale does at least), But there are games I would like to play that are 32-bit. No luck for me or can anything be done to fix this?
thanks a lot Apple :steamsad:

Revert to an older version of mac that was released before Catalina (like Mojave 10.14 for example)

Or use BootCamp, which might be a more difficult process.
