Can I trash my OS 9

Posted:
in Genius Bar edited January 2014
Do I need OS 9 for any reason? I don't forsee or have had to use OS 9 for the last couple years. Can I, should I, how do I trash it?

I have the Quicksilver G4.

Another thing. When I go into System Pref and Startup Disk, I have two OS 9 options, 9.1 & 9.22

If I can't totally trash OS 9 how would I get rid of one of the two OS 9's

    poor OS 9 I miss it so much sometimes.



    anyhow, click on finder and open the root of the hard drive. trash "System Folder" Folder (not the "System" Folder -- that's OS X) and "Applications (Mac OS 9)"



    that's all there is to it. if you've got the room (~ 300mb) i'd recommend keeping them on there though...you never know when you'll need a gopher client. seriously though, occasionally you might run across some OS 9-only program you'll want to run.

    Why didn't you relocate the OS 9 System Folder to a better location a while ago?

    When I drag my OS9 system folder to trash it says "The operation cannot be completed because the item "System Folder" is required by the System



    I don't think I get the "root" bit

    it turns out my advice was wrong for tiger (any reports for Panther/Jaguar?)



    I found these pretty good instructions online about how to do it if you're getting the warning you had:

    Thanks progmac, the only difficult bit now being that my Mac won't boot in single user Just tried 3 times, twice as restart and once as a full shutdown and power up from button. Held down "s" and OSX booted in every time I have had this Mac in SU when I had some troublesome video drivers, but it was a techy mate who did it. Any ideas why it won't go into SU ?



    Would it be possible to boot off the X install CD and trash OS9 from there, or will "System" still need "Classic" ?

    OK, so it's Cmd-S



    Rebooted in SU, and the command prompts on the link weren't recognised



    I presume that you do not type the "$" and the " /" signifies a return.

    $ mount -uw /

    $ cd /

    $ rm -rf 'System Folder'



    In SU it appears as.....

    Quote:

    Singleuser boot -- fsck not done

    Root device is mounted read-only

    If you want to make modifications to files,

    run '/sbin/fsck -y' first and then '/sbin/mount -uw /'

    localhost:/ root#



    Where am I going wrong, as single user is scary

    you should indeed be typing the " /" -- it is pointing to the root level of your hard drive. otherwise, you wouldn't be specifying a location. any luck?

    Right, when I type...



    localhost:/ root# mount -uw/



    ...I get...



    mount: illegal option -- /

    usage: mount [dfruvw] [-o options] [-t ufs | external_type] special node

    mount: [-adfruvw] [-t ufs | external type]

    mount [-dfruvw] special | node

    localhost:/ cd/: No such file or directory
