What are the differences between a macOS update, upgrade, and reinstallation?
The following describes the differences between a macOS update, upgrade, and reinstallation:
- macOS update: Installs an incremental update of macOS but doesn’t upgrade it to the next major version.
- macOS upgrade: Installs the next major standalone version.
- Reinstall: Installs the same major version of macOS on a disk that already has macOS installed. (This overwrites the existing system files but leaves apps, user home folders, and other files in-place.)
