Yes, currently on the beta is crashes the system but not the entire computer. It basically makes it go from where you were to as if you just logged into your Mac. Might be related to the beta and how it handles encountering a 32bit app. Any other app that is 32bit will just show an alert it can't be launched but since GW2 is 64bit but loads the 32bit UI thing it seems to freak out Catalina. Like others said the ball is in Arena's court. @DrMORO.4627 I dont think you should hold off getting a Mac just because of GW2 not working on Catalina, also Catalina doesn't come out till September I think, so it wont ship with it installed (Mojave instead)
