Beware installing macOS Mojave ! Apple appear to have completely take away the power todownload the installers of older versions of macOSand Mac OS X from the new reading of the Mac operating scheme .
Previously user could go to the Mac App Store , tap the buy tab and see a tilt of all the apps they had ever download .
This was particularly useful if a Mac user wanted torevert to an older version of Mac OSX , orrun more than one version of the operate system(perhaps for testing , or because they were run old software ) .
It was previously possible to turn up an older version of Mac OS X in the Purchased tab , re - download its installer , and then follow various steps(outlined here ) to make a bootable installer on an international drive . This bootable installer could then be used to do aclean install of the earliest variant of the MacOSon the Mac .
Now that Apple has updated the Mac App Store in macOS Mojave , there is no longer a Purchased tab key . Users can see some of their previously purchased items if they tap Store in the Apple Store and choose : View My Account . However , this will no longer show any older versions of MacOS , though it did antecedently .
In 2017 , when Apple introduced MacOS High Sierra , the company did remove Sierra from the buy inclination , which made it more hard to revert to that earlier interpretation , but it was still potential to download the Sierra installer via thislinkthat Apple offer
The link still withdraw you to a page for macOS Sierra , but if you are run Mojave you will see an “ Update not find ” error subject matter if you seek to download it .
We have check the same link to the Mac App Store on a computer that had n’t get down Mojave install and can confirm that it is still possible to download the installer .
We also tested the tie Apple provide to download El Capitan back when High Sierra launched ( here ) . But that download also no longer is likely valid if you access it in Mojave , with the message “ Update not found : The requested version of macOS is not available ” appearance .
Again , we were capable to corroborate that El Capitan installer could be downloaded on a Mac run High Sierra and on one running Sierra .
To reiterate , it is possible to download the installer for an senior versions the Mac App Store but only if you are lam macOS High Sierra or older . If you are run away macOS Mojave this will not be potential .
In fact , Apple even states as much on its Sir Frederick Handley Page about make a bootable installer , here . It say : “ To download macOS Mojave or High Sierra for this purpose , download from a Mac that is using macOS Sierra 10.12.5 or later , or El Capitan 10.11.6 . ”
This have in mind that we have to recommend that you download the installer for High Sierra , and any other installer you finger you may need in the future tense before updating to Mojave .
To chink to see if you have the installer you take on your Mac , perform a Spotlight search , for Sierra or High Sierra for example .
as luck would have it , we already have the various installers on our Mac . If you do n’t have them available on your Mac then we advocate retrieve a Mac that has n’t got Mojave instal , log on with your iCloud ID and viewing the purchase tab in the Mac App Store where you should be able to download the installer you need .
