How to tell what version of Mac OSX?

Hello;

I am a person who works for a university here in the US. Alot of the times, I have macs that dont boot, but I can see the data from the hard drive, via an external dock. Is there a way to tell what version of the OS is from a strictly file level? Without being booted into the OS?

Thanks,

Brian

iMac (27-inch Late 2009), Mac OS X (10.7.5)

If you have access to the disk drive from another computer, then you can do a Get Info on the drive. It should display the version of OS X installed on the drive in the upper panel.

If the computer's booted into an OS which doesn't support that(not all Mac OS X versions do), open the file /System/Library/CoreServices/SystemVersion.plist in any text editor.
