@tristan-k I recommend using the regular amd64 version with rosetta. The native build still has a lot of problems that make it pretty unusable (crashes when switching audio devices, no hotkey support, …)

Thanks for the heads-up. I guess will have to wait then. If you need someone for testing just holler.
