A quick look at my Steam library shows that out of the last 20 PC games I played, only five are available on Mac. Almost no one uses a Mac as their primary gaming machine because neither the hardware nor software are there. Another shortcoming is Apple’s inflexible hardware strategy, as the company often goes for pedestrian GPUs and unpopular experiments like the MacBook Pro’s Touch Bar without offering other options.
The games that do come to macOS often run better when booted into Windows on the same machine. Even though Steam came to the Mac in 2010, Windows remains streets ahead in terms of the number of games released. When you think about the weaknesses of the Mac platform, a couple of obvious areas spring to mind.
