Determining the Current Mac OS Version
If you're not sure what version of the Mac operating system you've currently installed on your computer, you can use the Startup Disk utility to find out. If you're upgrading from Mac OS 9, you can access the utility from the Control Panel on the Apple menu. If you're using Mac OS X, you can access the utility from System Preferences on the Apple menu. A quick visual way to determine which operating system, either Mac OS 9 or X, is installed on your computer is to check the Apple icon on the left side of the menu bar. If a six color apple appears, you're using Mac OS 9.2 or earlier. If a blue 3-D apple appears, you're using Mac OS X or later.
