I actually spent my first week back playing with a 15' Macbook Pro from 2018, with i7 and intel graphics.. Lets just say it worked -well enough- to be on and communicate, but not well enough to where I considered it playing long term, so I bought a laptop that's more built for the requirements of running GTAW smoothly. I wouldn't recommend it, but it's a good backup if your main PC ever fails or something.
I used Parallels Desktop, and it works as if it's a Windows computer, very neat. If you're playing the steam version I've found that on either one of the computers, you have to close Steam via the task manager.
