You may want to reinstall macOS for a variety of reasons. Perhaps your Mac is acting differently and you believe a fresh installation of the operating system can solve the problem.
Alternatively, you may be thinking about selling your Mac or giving it to a family member.
It’s also possible to reinstall the macOS version that came with your Mac, which might enable you to go back to an older version of the operating system if the current version is causing you problems.
