So there was an Apple rep on my campus today. He didn't say much we don't know. In response to an ssh question he said it would be in the update which should come out soon. He made it sound like "this week" kind of soon.


More interesting.

He said that when OS X ships on new boxes this summer there will be an AppleScript to uninstall X. So you get your new box. Boot into 9 and run the AppleScript to delete of all of X.

How do uninstallers usually work? I guess I've never given this much thought. I mean, what's the difference between creating a small classic app that uninstalls X after you've booted into 9? Less code overhead with the script?

I'm clueless.

Either way, it's good to know that (a) the update will be out soon and (b) there will be some kind of uninstaller. Wiping the drive gets annoying if you have other stuff on there. Not very "user friendly" either.

And as for the app vs script thing, I don't know why they chose that. The functionality would be the same either way.

I don't see what the big deal about needing an uninstaller is. I "uninstalled" DP4, Public Beta, and build 4K17 manually with a little bit of help from ResEdit. And erasing the disk that OS X is on is TOTALLY unnecessary.

If you've installed Mac OS X over Mac OS 9.1 on a drive and want to remove the Mac OS X items from the drive:

- reboot into Mac OS 9.1
- paste this script into a new script window in the script editor and save it as a classic applet. quit script editor.
- run this script

All Mac OS X items will be placed in the trash.

BEFORE YOU EMPTY THE TRASH, MAKE SURE THAT IT DOES NOT CONTAIN ITEMS YOU WANT TO KEEP!

God, I love you guys that write AppleScript!!!

This applet worked great! I can't thank you enough!!! Where do i send the check

You can't include "Users" because it uses the OS 9 multi-users "Users" folder. Much more safe to leave that one out.

[Lord Kronos]

One little mistake: it's 'mach_kernel' and not 'mac_kernel'. But it sure is a nice script .

Edit: you may also add '.Trashes' and '.vol' to the list.

Here's a version with your suggested changes. The script will now ask if you want to delete the Users folder.

Code:
property root_items : {"bin", "dev", "Network", "private", �
	"sbin", "usr", "Volumes", ".DS_Store", ".hidden", "cores", �
	"etc", "tmp", "var", "Applications", "Developer", �
	"Library", "mach", "mach.sym", "mach_kernel", "System", �
	".Trashes", "Users", ".vol"}
property systemfolder_items : {"Classic", "Classic Support", �
	"Classic Support UI", "ProxyApp"}

tell application "Finder"
	activate
	try
		set this_version to the version as string
		if this_version does not start with "9" or �
			this_version is not greater than or equal to "9.1" then �
			error "This script requires a Mac OS 9.x system greater than 9.0.4."
		display dialog "This script will move Mac OS X items from the startup disk to the trash." with icon 2
		display dialog "Should this script delete the Users folder?" buttons {"Cancel", "Yes", "No"} default button 3
		set the users_flag to the button returned of the result
		repeat with i from 1 to the count of the root_items
			set this_item to item i of the root_items
			if this_item is not "Users" or �
				the users_flag is "Yes" then
				if exists (item this_item of the startup disk) then
					delete item this_item of the startup disk
				end if
			end if
		end repeat
		repeat with i from 1 to the count of the systemfolder_items
			set this_item to item i of the systemfolder_items
			if exists (item this_item of the system folder) then
				delete item this_item of the system folder
			end if
		end repeat
		beep
		display dialog "The Mac OS X items have been placed in the Trash."
	on error error_message number error_number
		if the error_number is not -128 then
			beep
			display dialog error_message buttons {"Cancel"} default button 1
		end if
	end try
end tell

I used the revised script and it seems to have worked fine -- up to a point.

When I rebooted my g4 there's a blue folder with a blinking questionmark. It stays on screen for a few seconds and then everything goes over to 9.1 and everything starts up fine.

What's THAT little drama about?

Some points:

(1) Did not delete the User folder
(2) Could not locate the mach_kernel file anywhere before going through the script and didn't see it in the trash.
(3) The problem I was having was that the startup disk feature in 9.1 suddenly vanished -- meaning I couldn't find any way to launch OS X. That was the thing that made me determined to get it off my computer. If I could have it there and update from time to time as apple releases something and eventually move toward using it, I suppose I would. But having it there without any advantage is senseless.

Anyway, that's my situation. Any answers are GREATLY appreciated!!

Open the startup disk control panel in Mac OS 9 and select the startup disk with the Mac OS 9 system folder. That should solve the problem of the blinking folder.

Hello Schmoo

Can I post your AppleScript on my Mac OS X-Site (http://www.thinkmacosx.com/)? There are a lot of german users asking if there is a simple way to remove Mac OS X. An Your script is a really nice and simple way to do it...

Thanx, Mathias Nater

And the other little mistake is that he left AppleInternal in his first list

Thanks to all for the email and help -- one problem remains, however, and it's the one that sent me down the rabbit hole to begin with!

When I go to control panel and select Startup Disk, I have only two choices up there -- File and Help. Under File there is only CLOSE and QUIT. There is no way to change or direct the startup. I noticed that happened out of the blue, I'd always been able to switch over to OS X via that control panel. I tried downloading the file again from apple but got something involving a "shrink wrap" error, as I recall.

So, I think I've got OSX off -- except for the USER folder , and I suspect there's a way to prune that! But I don't seem to have the option to stipulate that 9.1 is the system to start with.

Argh!

If you are booted into the 9 from the harddisk you should see you own HD icon in the startup disk control panel. Just highlight it and close the window. That should take care of any flashing "?". If the icon is not there ...???? You may want to do a restore in place install of OS 9.


The "User" folder is where OS X puts all the folders for the users. OS 9 uses the same "User" folder for OS 9 multi-user. If you are not using OS 9 mutli-user AND there's no files in there you want you can trash the whole thing. It not going to cause any trouble either way.
