Mac OS: Versions, builds included with Intel-based Macs

What version(s) of Mac OS X are included with Intel-based Macs?

Important: You cannot normally use a Mac OS version earlier than the one included with the computer.







Notes

  • "Some computers shipped with different Mac OS X versions at different times. When a computer was not bundled with a later version, a "-" appears in the "Later Mac OS included" column.

  • The build information is available in the About This Mac window.

  • 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 the computer.
