Apple has a page for each release that in older versions of the OS describes the features required in Macs to handle it, and in newer versions lists the oldest models supported or spell out every model. You can track it down, but you have to work in reverse. That is, how do you find the last version your computer is compatible with? And some people keep older systems running indefinitely, as I noted in a recent column that started with people’s love of 10.6.8 Snow Leopard, now over a decade old.īut Apple doesn’t provide a guide as such as to the “terminal” version of its operating system you can install on any given computer. Apple has generally avoided that with Macs, letting many of its models receive OS X and macOS updates for five to seven years after the computer version’s initial release.
People accuse electronics manufacturers of built-in obsolescence: that hardware is designed to stop working or not be useful after a relatively short period of time.
