ArtRage Vitae (and ArtRage 6) work well on M1 Macs. Currently the support isn't native M1, but ArtRage has always been well optimized so you wont see performance issues.
The top of my 'to do' list for ArtRage Vita is add native M1 support for MacOS. (well, that and address the bug reports we always get on major update. )
The cool thing about being the App store is ArtRage Vitae owners will get the updates, features and fixes automatically without having to mess with installers and serial numbers.
