I'm trying to follow the directions on the Apple Support Page regarding Mass Deployment

Step 2 of the process says

On the server, install the app named "Install Mac OS X Lion" from the Mac App Store (a network connection is required for this process).

The problem here is that when I do a search for Install Mac OS X Lion in the App Store, I get no results found.

Where can I find this app in order to enable me to do mass deployment of OS X Lion across my network?


What you're probably looking for is a copy of the OS X Lion installer. If you saved a copy when you first installed Lion, great. If not, you'll need to re-download it from the Mac App Store.

  1. Launch the App Store and -click the Purchases tab. An "Install" button should appear next to Lion. Click it to re-download the installer.

  2. Once the installer finishes downloading, go to your Applications folder to find the installer itself. It is called Install Mac OS X Lion.

Further steps to get the DMG image:

  1. Right-click the installer and choose Show Package Contents from the contextual pop-up.

  2. Navigate to .../Contents/SharedSupport. There you'll find a disk image called InstallESD.dmg.

  • So maybe their language is wrong on the tutorial? I was looking for an app called Install OS X Lion where you're saying I should install an app called OS X Lion... is that right? – Chase Florell Jan 9 '12 at 19:09
  • Yes. The confusion is that the download is called Install Mac OS X Lion.app whereas the name in the Mac App Store is OS X Lion. – gentmatt Jan 9 '12 at 19:20
  • Nope, the App Store does not show the installer when searching for "Lion", "OS X Lion", "OS X Lion.app", "Install Mac OS X Lion", "Mac OS X Lion", or "Install Mac OS X Lion.app". I am choosing "App Store…" from the Apple menu on a Mac running Sierra. – Basil Bourque Nov 22 '17 at 7:18

I still see "Mac OS X Lion" on the homepage of the Mac App Store. Can't you see it there?

Did you try to search Mac OS X Lion or Lion?

You can re-download Lion from the App Store by clicking on "Purchase" with the alt key pressed. Only then will you be able to download. Otherwise, it's just noted as "installed".

Do you use the Mac App Store app and not the App Store from iTunes?
