Mac OS X: Versions and Names at a Glance

The "X" in Mac OS X stands for the roman 10. Only behind it, in the decimal range, follows the respective version number. We show you which version number listens to which proper name.

Mac OS X has even changed its spelling over the years.

Creative proper names are nothing new in the software scene. Google benennt Android nach Süßigkeiten, Apple setzt lieber auf Tiere, wenn auch nicht ausschließlich.

Mit dem Release von Sierra hat Apple übrigens die offizielle Schreibweise geändert: Anstatt „Mac OS“ heißt es nun „macOS“. However, since the old spelling has been around for so long, it is still very common. This will probably only change in a few years, when the successor versions of Sierra have long been on the market, and also as macOS.
