The Mac died, but long live the Apple Silicon Mac. With the advent of the Apple Silicon based MacBooks, the hardware has had a fundamental change bring excellent power/performance. With Metal 3/MetalFX, I expect that a number of exciting titles with fantastic performance will come to the Macverse.
Will it supplant PC gaming? Of course not, and I don't expect that the article writer implied that either. But for those that have purchased the new Apple Silicon series of MacBooks (which has been a surprisingly phenomenal market success for Apple), a number of select AAA titles will become available "natively".
It's more reborn and in its infancy.
I'm not saying one should run out and purchase an Apple Silicon MacBook for gaming, but it's not dead. It's got more legs than Google Stadia 😉
