The Apple-approved method of removing Classic Classic
There are older tips on removing Classic, such as this one, but I've found the official (Apple sanctioned) way to remove Classic (which is different from prior hints). I found the following method in the Tiger Security Configuration Guide (3MB PDF) -- and the rest of the document is also quite interesting.

Read on for Apple's recommend procedure for removing Classic...

This is taken verbatim (except for some formatting changes) from page 32 of the above-linked PDF...

Warning: Incorrectly entering any of the commands described in this task can erase critical data. Pay particular attention to correctly entering single quotes. Misplacing these single quotes can result in the removal of Mac OS X or applications.

To remove Mac OS 9 and Mac OS 9 applications and files:
  1. Log in to Mac OS X as an administrator who can use sudo to remove files. By default, all users who are administrators can use the sudo command to remove files. If you modify /etc/sudoers, you can choose which users can use sudo. For information about how to modify the /etc/sudoers file, enter man sudoers in a Terminal window.
  2. Open Terminal.
  3. Enter the following command to remove the Classic icon from System Preferences:
    $ sudo srm –rf '/System/Library/PreferencePanes/Classic.prefPane'
  4. Enter the following commands to remove Classic folders and files:
    $ sudo srm –rf '/System/Library/Classic/'
    $ sudo srm –rf '/System/Library/CoreServices/Classic Startup.app'
    $ sudo srm –rf \
    '/System/Library/UserTemplate/English.lproj/Desktop/Desktop (Mac OS 9)'
  5. Enter the following commands to remove Mac OS 9 folders and files:
    $ sudo srm –rf '/System Folder'
    $ sudo srm –rf '/Mac OS 9 Files/'
  6. Enter the following command to remove Mac OS 9 applications:
    sudo srm –rf '/Applications (Mac OS 9)'
  7. Restart the computer.
I haven't tested it, but since this is from an official Apple document, it should work just fine. [robg adds: I can't find anywhere on Apple's site where the above PDF is linked; I even checked their Security Page, but no mention there. I also think we're OK reproducing the above verbatim, as the document's licensing page states: "No part of this publication may be reproduced or transmitted for commercial purposes, such as selling copies of this publication or for providing paid-for support services." Since we're not selling it, nor providing paid-for support services, I think we're OK to use it.]

robg-- It's on this page at apple.com:

[link:]http://images.apple.com/server/documentation/

The Link name is "Mac OS X Server Security Configuration Guide"; the same file is linked as "Mac OS X Security COnfiguration Guide". The link itself is:

[link:]http://images.apple.com/server/pdfs/Tiger_Server_Security_Config.pdf

which can be found by doing a "Get Info" on the downloaded PDF.

My guess is that since you're posting on a commercial site (one that accepts paid advertising), that counts as "transmitted for commercial purposes". Then again, I am not a lawyer.

Yeah, that's exactly what I was going to say.

Apple can't copyright the "recipe" (the commands needed to remove Classic) but they can copyright their embodiment of the recipe (the supporting text and the text as a whole, the commands wrapped in the support text). To avoid infringing copyright the text would need to be rewritten.

None that this will not fully work with international versions of Classic since the system folder may have some other name than "System Folder" in int'l Mac OS 9 versions.

removing OS9 syst folder this way takes 3 hours!
Authored by: Herve5 on Sep 12, '06 01:49:51PM

Is it normal that the sudo srm -rf command with the system folder takes ages to complete?

I've left my poor mac alone in the dark for almost 2 hours tonight, and the syst folder only has decreased from some 20 Mb (seen from the Finder).

Would a basic authentified drag'ndrop to the bin have taken the same time?

Other than recovering disk space, is there any benefit to this?

This entire process took me roughly 4 hours and 30 mins to complete. I have a G4 Powerbook, 667 MHz, 512 MB RAM, 30 gig HD, and I'm running 10.3.9. Perhaps it wouldn't take such a long time on a faster machine.

A glitch when trying The Apple-approved method of removing Classic
Authored by: riktexan on Oct 10, '06 06:02:05PM

I have tried this method to remove Classic and have a problem right off.
After I enter the first command to remove the Classic icon is System Prefs I get this response.
tcsh: $: Command not found.
What does this mean and what do I do about it?
Thanks

Rick in Maine

You're not supposed to type the "$". That is a symbol that represents the UNIX prompt (whatever it might actually look like on your system).
