I disagree. When OS X went to Intel, there was an explosion of Mac games on Steam. Valve went all in with big ports of TF2 (complete with exclusive era-appropriate in-game items like the earbuds), and all their other games soon followed.

Apple self-owned themselves by slowly killing off support for this, culminating with the transition to the M chips and the upcoming removal of Rosetta to put the final nail in the coffin. Their negligence to support a major market is their downfall here. The hardware is more than willing, the software and company are causing the fumbles.

It could be argued that was a "right place at the right time" situation. macOS supported OpenGL at the same time as Valve was pushing for the original Steam Machine and native Linux ports. Writing a macOS port was a much easier job back then.

Apple's pivot to Metal and mobile-first distribution was the beginning of the end. The iPhone's revenue potential eclipsed the value that Mac gaming could ever provide, and Apple made sure to capture it with the App Store. Once Tim Cook showed everyone how easy it was to make service revenue, the execs probably realized that they could make bank off of a captive, game-deprived customerbase.
