I’ve posted a few old links in my time (as I near 4,000 posts it would be hard not to have some that are broken). But Apple App Store downloads seem to do better with not breaking links. So here are some to old versions of macOS and OS X, in case like me, you always seem to need some old thing for testing:

Download Os X Mountain Lion
The ninth major release of Apple’s server operating system is as big a change as the change from OS X Server 1.0 to OS X Server 10.0. In many ways, Mac OS X Lion Server (version 10.7) succeeds. OS X Mountain Lion is the ninth major release of Mac Operating System, Apple's desktop and server operating system for Macintosh computers. OS X Mountain Lion brings a lot of great things from iPhone, iPad, and iPod touch to the Mac. You can send iMessages. Get your Mac in on Game Center. Receive notifications.
