How to Install Mac OS Panther

When Mac system software increases by a full decimal point (from 10.2 to Mac OS Panther 10.3, for instance) it indicates that up to several hundred new and revamped features are included in the upgrade. Mac OS Panther is a very capable and fully modern Mac Operating System that is used by millions of people worldwide.

Difficulty: Moderate

Instructions

Things You'll Need:

• Mac OS Panther installation DVD
• Mac hardware that meets the minimum requirements

Check Your Hardware

1. Ensure that your Mac is capable of running Mac OS Panther by checking Apple's upgrade requirements (see Resources below).

2. Back up all of your important data. In a regular, problem-free OS installation, none of your non-system data should be altered or erased, but be prepared for the unexpected by backing up.

3. Check to see if your peripherals are compatible by consulting the Apple Device Compatibility Chart (see Resources below).

4. Make sure your older G3 doesn't need a firmware upgrade by consulting the Apple Firmware Upgrade Chart (see Resources below).

Begin the Process

5. Shut down your Mac and all peripherals, and disconnect any non-Apple devices from your computer before restarting.

6. Start up your Mac and make sure no other applications are active so that you can run "DiskUtility" (to ensure there are no drive problems that will prevent a smooth installation). This application is located in the "Utilities" folder, which is in the "Applications" folder.

7. Insert the installation DVD and start the upgrade process by opening the DVD icon and double-clicking on the "Install" icon. The installer application will cue you when the Mac needs to be restarted. This is required for the installer program to finish its work.

Install Panther

8. Follow the instructions on the screen, and choose one of the two upgrade methods: "Upgrade" will install the new system resources and leave your files and preferences alone, while "Archive and Install" will place existing system files in a folder named "Previous System" and install Mac OS Panther. Either way you can retain user and networking settings, as well as import multiple user profiles and associated "Home" directories.

9. Restart your Mac after the process is complete. If you opted for "Archive and Install," you can now customize the installation by manually copying any preference files or user settings from the "Previous System" folder to the same location(s) in the new system. Most of these items will be found in the old "Preferences" and "Application Support" folders (located in the old "Library" folders in "Previous System").

Tips & Warnings

• Have your administrator name and password ready.
• Don't be in a hurry with this or any other system-altering operation. Read all dialog boxes carefully and keep a printed set of these or similar instructions handy at all times (a good Mac reference book will do the trick, too).
• If you attempt to install Mac OS Panther on a Mac with a newer OS already installed, the entire drive will have to be reformatted. Make doubly sure that all of your important data is backed up first or you will lose it.
• If you are upgrading from OS 9 for the first time, you will need to confirm that your peripherals are compatible with OS X.
• If you are installing to a laptop, plug it in to AC power so that it can't power down during the installation.
