Mac OS 10.13 or later
How can I get Mac 10.13 or later on my Mac Air? I can't watch movies or much anything else without this.
MacBook Air 13″, OS X 10.10
Back up your data, check your applications for compatibility, and if your MacBook Air model is recent enough, click on High Sierra, Mojave, Catalina, Big Sur, or Monterey.
