I own old versions of Mac OS X, Mountain Lion in particular. The old versions are listed in the "Purchases" list within App Store app on my Mac.
But when I hit the "Download" button a message appears refusing to start the download because my MacBook Pro is too new and does not support that OS.
Other Questions are similar to this but not quite the same.
- Others say to use the App Store to download, but no mention of the App Store refusal that I encounter.
- Others suggest using developer.apple.com, but even with a paid membership that download page no longer offers old versions. The Download page offers only 2 versions: the current version (Yosemite) and the future beta (El Capitan).
My goal is to install Mac OS X on a virtual machine, Parallels.
