How to check your Install OS X app's version (Guide + App)

[shilohh]

Here is a walk through of how to check the exact version of OS X to be installed when you run the "Install OS X" app from the AppStore or create a USB installer from it. You can also do this for old installers that you may have collected over time.

Right click “Install OS X [OS Name].app” and choose “Show Package Contents”. Navigate to Contents/SharedSupport and mount InstallESD.dmg (double click it).


Terminal:

open /Volumes/OS\ X\ Install\ ESD/BaseSystem.dmg

Terminal:

open /Volumes/OS\ X\ Base\ System/System/Library/CoreServices/SystemVersion.plist

To Eject the previously mounted volumes using the Terminal:

diskutil eject /Volumes/OS\ X\ Base\ System;diskutil eject /Volumes/OS\ X\ Install\ ESD

If you prefer a automated approach, download the attached "Show OS X Installer Version.app" and double click to run it or drag and drop your Install OS X app on to it.

You're welcome. I've been meaning to make the app for a while now and it's definitely coming in handy for me. Enjoy
