                      Frequently Asked Questions

                      Where do I check for macOS updates?

                      Apple publishes major macOS versions and smaller updates over time.

                      To see which update your Mac can install, open System Settings > General > Software Update. Availability depends on your Mac model and installed version.

                      What should I do if I experience issues after updating macOS?

                      Restart your Mac and check System Settings > General > Software Update for another update.

                      If the issue continues, read our guide to a slow Mac after an update or contact Apple Support.

                      What if my Mac is not compatible with the latest macOS?

                      Use About This Mac to identify your model and installed macOS, then compare it with Apple’s current compatibility list.

                      You can keep using the macOS version already installed, but check Apple’s security releases to see whether it still receives updates.
