The honest reason 303 games won't run on your Mac.

It is not your Mac. It is not the graphics. Every game on this page is blocked bykernel-level anti-cheat — software that must run deep inside Windows itself, at a level macOS does not expose to any compatibility layer. No tool can honestly work around it, and anyone who claims otherwise is selling something. Whether these games ever run on Mac is a decision that belongs to each publisher.
