Mac OS X Installation Documentation 

I was recently digging around a bunch of old Mac OS X installers, and thought it would be fun to share Apple’s installation documentation for a bunch of releases.

All of these links are to PDFs. Right-click to download. The entire group can be downloaded as a .zip here.

OS X Lion was the first version of Mac OS X purchased and downloaded via the Mac App Store. It and all later versions do not include this type of documentation.
