Cannot launch game on macOS High Sierra

[ne0dym]

Update: Since the Mac client didn't work, I decided to simply try and install the Windows client using Wine instead. It took a lot of trial and error to figure out how to solve some DirectX errors I was getting but eventually I managed to get the game to launch perfectly. It runs as well as the native Mac client did, maybe even a little better, which means it's not completely smooth but should be playable. It's funny that the official client wouldn't work but my own Wine wrapped version does lmao. When the game goes on sale again I will definitely buy the Windows license. If anyone has the same issue and would like to try what I did, I'll be happy to (attempt to) explain my solution.

Eh, not really that odd. Crossover is a tweaked, optimized version of Wine, and moreover probably one derived from a version of Wine later than installing wine-stable from Homebrew on High Sierra will get you. In particular, Crossover (and Wine in general) needed a bunch of changes to support running 32-bit Windows executables on a 64-bit-only operating system (i.e. Catalina), so they did all kinds of stuff to make the graphics pipeline theoretically more powerful while in there. Unfortunately, all those upgrades also bumped the base version of MacOS required, presumably because (as witnessed above) some of those changes didn't work right on older systems.

Wrapping it in the base version of Wine that you did is basically like taking the current client and stuffing it into an older build of Crossover; on an old system, wholly viable. On a 64-bit-only system like Catalina or Big Sur, though, running the old version would simply fail. And I'm guessing they came down on the side of Catalina and Big Sur support being higher priority to them than continuing to support anything prior to Mojave.
