Help with 1.3 update for Mac

[Mudbill]

If you're running macOS 10.14 Mojave (and I think also High Sierra) then you'll get a warning about compatibility because Amnesia is 32-bit which is being discontinued in 10.15 Catalina. They should still run despite the warning though, unless you're running on Catalina already, in which case it won't run until an update to Amnesia is pushed.
If you can run it despite the warning, go ahead. It won't actually cause any issues.
