How to find Which Version of Mac OS I Have?
Article by: Amit Chawla
“I want to know if I have System 7, OS 9, OS X, or what. How do I tell which Macintosh operating system I have?”
Resolution:
At the top-left corner of the screen, you can find a little Apple logo. This is known as Apple Menu.
You’re in OS 9 or earlier, if it’s rainbow-colored.
If it’s blue or gray, you have some version of OS X (“X” is for “ten”, like the roman numeral).
Click on that Apple to open the Apple menu, and choose the first item on the list: it will be About This Mac, or About This Computer, or About This Macintosh.
A window will open letting you which version of MAC you have. That’s it!
Not at the computer?
If you know the nickname of your Operating System, you still be able to figure it out. Such as, Panther, than you have some version of OS X.
Ø Cheetah is 10.0,
Ø Puma is 10.1,
Ø Jaguar is 10.2,
Ø Panther is 10.3,i
Ø Tiger is 10.4
It has OS 9 or earlier unless you’ve bought and installed OS X, if your computer was made before March 2001.
It has System 8 unless you’ve bought and installed a later version, if your computer was made before October 1999.
It has System 7 unless you’ve bought and installed a later version, if your computer was made before January 1998.
Then you had better hope it’s been upgraded to System 7, or you’ll have a real hard time getting on the internet, if your computer was made before 1991.
You can download Mactracker (onto a working computer, of course) and look up your model, if you have bought a used Mac Computer.
