Valve has discontinued support for Counter-Strike 2 on Macs and older PCs.
Future Counter-Strike 2 will exclusively support 64-bit Windows and Linux operating systems. Players who can’t run Counter-Strike 2 on current hardware will be able to access an outdated version of CS:GO. This is a frozen build of the game that has all the features except Valve’s official matchmaking.
The game will be available on 64-bit Windows and Linux.

Support for this version of CS:GO will end on January 1, 2024, after which it will still be available, but some features that depend on Game Coordinator compatibility (such as inventory access) may degrade and/or not work.
