Fallout 4 is now DRM free on GOG and it works very well under Crossover 23.6. Create a new Windows 10 bottle and install the core fonts, MSXML3, the Visual Runtime setup, and DirectX for modern games. You still need to add the tweaks from AppleGamingWiki for the mouse and sound to get it up and running. Also, use BethINI to configure the graphics settings. You need to make sure godrays and ocular occlusion are turned off. I'm running it with D3DMetal enabled. It works really well. Not quite to five stars, but I'd rate it 4 stars. None of the quirks with the Steam version are present for the GOG version and sound works great.
BTW, I'm on a MacBook Pro M1 PRO with 16gb of RAM. I'd love to see this run on the Max chip with more memory.
