Currently there are several problems with a) 64-bit clients b) new Catalina-compatible CrossOver wrapper.
We have some progress (in the last release we fixed the sound loading) but the fact that all my attempts to install the hackintosh didn't succeed slows down the progress.
By the way, for macOS versions prior to Catalina, there is workaround to use generic Wine instead of Wargaming wrapper to launch World of Tanks.
@fsdgsg You also have various other mods, such as mod_calculator_rankings_battle, which may be incompatible with macOS because of differences in the working directory for Windows and MacOS. We fixed this for our mod, but other mods usually do not contain this fix.
It will be fixed in the vanilla WoT no earlier than 1.7.0 (end of November, I think).
