Because i have to test my os x app with an older mac os x version (to make sure it is still compatible) i would like to setup a vm with an older os x version (el capitan or yosemite) using parallels desktop. in order to create the vm a need the installer package.. Ok, i discovered that if i go into the app store and dig through my purchaces, i can re-download the os x 10.7, 10.8, and 10.9 installers, transfer them to another system, and install them there.. 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. how to download old version of mac os x that i own and app store lists, but app store refuses on newer mac the problem here is that a 2013 macbookair will refuse to download a 2010 os x lion.
How to download an old version of mac os x. as long as you have not installed mojave ($99) a year to join the apple developer program and you have to sign a non disclosure agreement.. Without app store: download mac os version as apple developer if you are signed with an apple developer account, you can get access to products that are no longer listed on the app store. if you desperately need a lower os x version build, consider creating a new developer account among other options.. This development suggests apple is intentionally rendering recent mac computers obsolete and not because there is anything wrong with older hardware: install os x mountain lion developer preview on old unsupported macs..
