Please help!

I'm trying to find which version of OSX is installed on an old MacBook Pro which won't boot up.

I can see the hard disk and all its files from another Macbook Pro when the broken one is in Target Disk Mode.

Is there any system file I can search for that will give me a clue??

Click to expand...

Write this in a Terminal-window:

defaults read /Volumes/YourDiskName/System/Library/CoreServices/SystemVersion ProductVersion

Click to expand...

Drag the disk icon from the desktop or from another location to the Terminal window, to obtain the correct path for the disk.

Many thanks Mr. Retrofire.

You won't believe how difficult it is trying to do a search for an answer to this question. 🙂

You can also "get info" on the disk and it will show you the version there.
