Dumb Switcher question:

How do I best uninstall OS 9 Classic. I don't need Classic, I prefer an OS X-only machine.

My guesses:
a) delete OS 9 folders in Finder
b) format machine, reinstall OS X from DVD
c) ?

Thanks for your advice.

The best option is (b), rebuild the machine from the DVD installing OS X only.

Obviously, option "b" is the ideal situation, but you can do option "a" as well if you don't want to format the machine. By the way, I believe there's a folder called "My documents" or some such thing that is for MacOS 9. Just make sure it doesn't have anything you want to keep in it. I assume you have no installers that require MacOS 9? Some older apps require MacOS 9 to install and then have a patch for OS X.

Since OS 9 is completely self-contained in the System Folder, it's as easy as removing that folder (and the Documents and Applications (OS 9) folders if you want... these are both OS 9 specific) from the root level of your hard disk. There is really no need to wipe and do a restore off the CD. Since the Finder won't let you do it by dragging them to the trash, you'll just have to do it manually. In case you don't know how to do this:

1. Open Terminal
2. Type "sudo rm -rf " (note space after -rf) but DO NOT press return
3. Select and drag those three folders into the Terminal window
4. Press return and and enter your password

Easy!

Be careful with the sudo rm -rf command. It has the power to delete any folder without any warning whatsoever. Even your OS X system folder! So make sure you know what you're doing before you delete anything! I take no responsibility for anything you may accidentally delete by using this method.

Hope this helps!
