What Mac OS operating system do I need to open the launcher

I'm sure this has been answered at some point but I can't find the thread.

I'm on Catalina 10.15.3 and it's not launching, which version do I need to downgrade to?

Thanks

with Catalina = you can NOT use 32 bit app.

With Mojave = you can play by changing just 1 file ( you need to use this one: https://mega.nz/#!w953AThS!IujGFBQPL...Sgpr4RAsYgiNtk )

With High Sierra = you just need to do this to make the app run: http://forum.warmane.com/showthread....=1#post2609459

Hey, I saw this thread and was wondering if the game client got updated to support MacOS Big Sur or Catalina recently?
