Switching Between Operating Systems
Your computer is set to use Mac OS 9. You can switch between Mac OS 9 and Mac OS X.
Once you’ve set your computer to use OS X, it will always start up using OS X until you set it
to use Mac OS 9.
To set your computer to start up using Mac OS X:
1 In Mac OS 9, choose Control Panels from the Apple (K) menu, then choose Startup Disk.
2 In the Startup Disk control panel, double-click the hard disk that contains your operating
systems and select the Mac OS X System folder as your startup disk. You can click the
triangle to the left of the hard disk icon to see the System folders installed on it.
Restart your computer.
Note: Because Apple frequently releases new versions and updates to its system software,
the version number of the Mac OS X and Mac OS 9 operating systems in this manual may be
different from those installed on your computer.
