Mac OS X versions (builds) for computers

Learn which Mac OS X versions (builds) originally shipped with or are available for your computer via retail discs, downloads, or Software Update.

Learn more about the builds available for your Intel-based Mac. If you have a PowerPC-based Mac, see Mac OS: Versions, builds included with PowerPC Macs (since 1998) instead.

Tips

  1. Some computers shipped with different Mac OS X versions at different times. When a computer is not bundled with a later version, a "-" appears in the "Later Mac OS X included" column.
  2. The build information is available in the About This Mac window when you click the word "Version".
  3. Some Macs may include a slightly later build version (but same numbered version) of Mac OS X on the Install or Restore discs than was preinstalled on your computer.
  4. Do not use a Mac OS X version earlier than the one included with the computer.
  5. If you're using the Recovery Disk Assistant, you can only use the external recovery drive with the computer that created it.
