The use of a
macOS compatibility checker enables users to know which versions of operating systems their computer supports. To begin, find out your specific Mac model and year using "About This Mac". After that, go to System Settings > General > Software Update to see what is available for installation and upgrade. Your computer will provide you with information about the software that it supports according to its hardware and OS. In case you want to do a detailed comparison, check the models supported by a desired version of macOS.
