How to unistall OS9?

macaficionado · February 5, 2003 4:45PM

Sorry if this has been posted before, and I've seen similar posts, but do not seem to get it.

I have a DP867 and would like to erase, uninstall the OS9 partition on the HD.

What is the best way of doing this, is it doing a clean install of Jaguar or can I just drag something to the trash?

I have not used OS 9 since I got my machine and would like to take the excess off of the HD.

Thank you

MA

I don't know how to unistall os 9 but I have a similar question so I figured I should say it here rather than a new topic. I want to know about uninstalling regular applications. I am on my first Mac (Powerbook 867 15") and am doing my best to play around but do I just delete the folder with the contents and then it is deleted or is there a special way to delete programs?

To uninstall OS 9, drag the OS 9 System Folder into the trash. Then empty the trash. Then delete any OS 9 applications you don't want.

OS 9 is nothing like OS X. You can just drag system folders around and it causes no problems.

Luca's way will work, but the way I have always done it is I just backed up my OSX files and apps on a firewire hd, then I just did a complete wipe of my computer.

Inspired by this thread, I gave the OS 9 System Folder and my Applications (OS 9) folder a righteous "heave ho" a couple of hours ago.

I ain't lookin' back either!

Cool thing, I freed up over two GB, so that's nice. Down to OS X only on this iMac. I couldn't boot in 9 or Classic even if I WANTED to!

There is absolutely no need to reformat your HD. There really isn't. OS 9 doesn't scatter stuff about. It's all in that system folder. Delete it and any apps you don't want and you're done. No muss, no fuss. I haven't used 9 in I don't know how long. Even classic. Thank god.

Go heels.

Exactly. I think I've booted into OS 9 TWICE since last March because of some - at the time - printing issue. I've never launched Classic from within OS X. Everything I have and use is OS X-native so there was no need for me keep an OS on board that never got used.

My iMac feels lighter already!

troubleshooting a fairly new Mac today... a co-workers' which has been around since November. I selected OS 9 from startup disc to see if the hardware problem showed up there also (which it did)... it booted into the OS 9 registration screen 'cause it had NEVER been started up in 9 in its 4 month life (although Classic has started up a few times)

Hey Guys,

I'm not too seasoned in Mac OS yet, and trying to do this only shows me this :

"The operation could not be completed because it is owned by the root"

What's up with that?

Select the folder in the Finder and choose Get Info from the File menu. Click the disclosure triangle by "Ownership & Permissions" and then click the little padlock to allow access to change it (you must be the admin user of the computer to do this). In the menu by Owner, change it to your current username. You should then be prompted for your admin password. Once the new owner is set, also click the "Apply to enclosed items" button. This step may not be necessary, but it can't hurt either since you are just throwing away everything in it anyway.

Now you should be able to successfully trash it.

Hope this helps.

I get a different message....

The operation could not be completed because item "System Folder" is required by the System.

I was able to delete some things but I see classic stuff all over the place and I did not succesfully delete the OS 9 partition in the HD, so the question is:

Exactly what do I have to backup, aside from the obvious(Quicken files, video, MP3's, etc), so as to not loose the apps as they are, before I reinstall OS X?

Thank you

Ok, can I just copy the whole contents of the hard drive and then reinstall without the OS 9 partition and then restore the old OS X harddrive?

macaficionado · February 15, 2003 10:26PM

So I was never able to delete everything of OS 9 and Classic, I deleted some things, but there was a whole lot of stuff left that I just did not want.

Whatever I did even created a folder that is still unknown to me as to what it was. It was named "sw" and had some files with a .lib extension that I have no clue what it was.

It just got too cluttery for my taste, so when I finished an editing job that I was doing, I decided to give it a go and install OS X from scratch. First I copied the contents of the HD into an external HD, I then made a disk image of the HD just in case.

Intalled OS X, the first OS I ever install, without a problem, as a matter of fact it was too easy. Having heard the nightmares of installing other operating systems, I was a bit nervous.

My concern was FCP3 with all the preferences, and all the work I went through, but It is unbeleivable how this worked. I just copied the folders from the bakup that I had made and there it was FCP running without a true installation as I knew them.

So everything is back to normal, but I still needed to upgrade OS X from 10.2.1 to 10.2.4, because it was the only choice, I was skeptical, since I've been reading horror stories about 10.2.4 but I've been running it without a problem, it actually feels snappier.

So now my Hard drive is as clean as can be and I am one happy Machead.

Thank you for all the suggestions.

Where are you hearing all these horror stories?

The /sw directory is installed by either <a href="http://fink.sourceforge.net"; target="_blank">fink</a> or Virex 7.1

The reason you were left with the OS 9 partition is because you cannot delete partions without reformating your drive.

I went X-only yesterday: I've kept a .dmg of my old OS 9 installation kicking around, but I can't see it getting any use...

I used Terminal, though: gotta love that sudo rm -r
