Hi, I was looking for a bit of clarification on the rules. I see PC as an option but not Mac. Is the Steam version on Mac accepted?

Also, it shows my version as 2.4.2 but would there be a way to run on the Legacy 100% leaderboard? Would it have to do with enabling Glitchrunner mode to be able to do glitches from past versions?

Thanks in advance!

I'm very late to this question, but Mac falls under PC, as does Linux! The Steam version is the most up-to-date (official) release of the game, and to run Legacy you need to downgrade to version 2.2 through the archived version under betas on Steam.
