How to download old version of Mac OS X that I own and App Store lists, but App Store refuses on newer Mac 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.
If you go to developer.apple.com/downloads you will find all downloads that Apple has available.  Limit your search to the "OS X" category and you'll see downloads for all versions of OS X from version 10.3 to 10.6. 

I'm guessing that 10.7 and up are missing because starting with 10.7, the OS was only available via the App store. Unfortunately, that means that you'll only be able to get the installer from the App store, and the only way I know of getting older version from the App store is if you have previously "purchased" that version and wish to download it again.
