Running a 14" 2023 M2 MBPro (OS13.5.1) and just installed Diablo4 and was very surprised that it worked after I changed the Windows Version to 11. No other settings were touched.
I forgot that I needed a mouse but it worked with the trackpad. Trying fighting while switching between left and right mouse click. NOT FUN.
I checked the settings and everything was set to high and it ran fine with no issues.
Was very impressed. Now I need to go give them my money so I can play the game for real.
