Im curious if anyone from the dev team can comment on the state of the 64bit Mac client. Currently a large subsection of Mac users are out of luck when running the game due to some tricky bits with Catalina, Direct X 11 translations, and 32bit sub programs (of which Catalina will not support at all.) Anything not running a AMD graphics chip is incapable ATM. Sad, considering that over 80% of Macs run an Intel graphics chip, most being better than the minimum requirement if your MacBook is post 2013.
Right now the official statements are to downgrade to MacOS Mojave in order to play.
