Summary

What is a "Reference Release" of the Mac OS?

Products Affected

Mac OS X 10.4, Mac OS X 10.3, Mac OS X 10.2, Mac OS X 10.1, Mac OS X 10.0, Mac OS X 10.5, Mac OS 9, Mac OS 8

The phrase "reference release" means that the software is distributed as a stand-alone system software package that can be installed regardless of the version of Mac OS currently installed (assuming the Mac is compatible with the reference release). Note: You should not install Mac OS versions that are older than what came with your computer.
