I don’t run Parallels to achieve ‘native’ Archicad support on M1 and M2 and I don’t bunk that would work anyway. However, I do run it for accessing the older versions of Archicad for Archive projects and I also use it for checking bugs in the latest version between the Mac and PC versions. Archicad running through Parallels is much slower due to the emulation. I would imagine you’ll get better performance running Archicad on the M1/M2 Macs making use of Rosetta. As I understand it the native version is coming soon, maybe later this year.
