Ok, native Metal 3d viewport is ++++. Tested on a Macbook Pro M1 32 core 62gb ram Ventura.

- In Properties > Render Properties > Cycles => set device to "GPU Compute"

- In Preferences > System set Render Devices to Apple M1*, GPU Backend to "Metal"

- If you have a scene open it will black out for a few, mine was about 20 sec

Very much faster and better
