Apple just unveiled the next version of its Mac operating system: MacOS Sierra.

That's right: Confirming earlier rumors, Apple announced today during its WWDC developer conference that it is renaming its desktop operating system from OS X to MacOS.

Here's an early look at the new features coming to Macs with MacOS Sierra. The update is available now for Apple Developers, and it will open up to everyone in "public beta" form next month.

Apple first debuted the Mac operating system in 1984, and at the time it was simply called Mac OS. Mac OS X came out in 2001, and in 2012 the Mac part was dropped from the name with the release of OS X Mountain Lion. The OS X name reached the grand old age of 15 earlier this year, but with the pending release of iOS 10, a parallel OS X operating system could be confusing. Hence the rebrand.
