There are, sadly, many games still available on the Steam store that will only run on pre-Catalina versions of the macOS, and we recently had to delete dozens of old games from our list of the best Mac games. And, just to make things worse, the arrival of macOS Catalina (10.15) a few years ago – which moved the macOS to 64-bit software and no longer supported older 32-bit software – killed off a lot of popular Mac games too. Apple has never been very interested in games on the Mac, and this has meant that Macs have never enjoyed the same range of A-List games titles as owners of Windows PCs or games consoles like the Sony Playstation or Microsoft’s XBox.
The Mac games scene is – not to put too fine a point on it – a bit of a mess these days.
