Steam dropped support for PCs running Windows 7, Windows 8, and Windows 8.1 earlier this week.

Now, the games store and platform is preparing to cut off older macOS releases as well.

Valve also says 98% of Steam users on macOS are already running macOS 10.15 or newer.

Unfortunately, this change also means most older macOS Steam games will be completely unavailable from Steam.

In some cases, like with SimCity 4, updated versions are available only through the Mac App Store.

Intel-based Macs can still play the Windows versions by installing Windows throughBoot Camp.
