MacOS Sierra (version 10.12) is the thirteenth major release of macOS (previously OS X), Apple Inc's desktop and server operating system for Macintosh computers. The successor to OS X El Capitan, it is the first version of the operating system issued under the June 2016 rebranding as macOS. I have a Mac Pro 5.1 mid-2010 (2.4ghz eight core) running El Capitan that I use in my music home studio. I have Logic Pro X installed on this machine, and plan to use it exclusively for music recording and production.
