Where to find the build number INSIDE an install DVD of Mac OS X

Question

It's not written on the DVD itself and I don't have the DVD sleeve anymore.

Answer 1

Not exactly through the DVD as you asked, but Apple provides a list will all the build numbers for the Retail installation disks.

Once you've run the Installer, you could always go to the Apple Menu () and choose About this Installer, which should provide the build number.

Answer 2

Check the SystemVersion.plist file that is on the Install Media.

Within the install media is the file containing the Build number, it is located at /System/Library/CoreServices/SystemVersion.plist

The string value for the Key ProductBuildVersion is the information you are looking for.

Note: This tip is useful for getting the Build versions on any OS X bootable disk, regardless of install ability.
