How to Delete a Previous Systems Folder in Mac Os x

[Flicker]

Hi,

I have a Previous System folder left over from my install of Leopard. It's nearly 3.5 gigs. Any suggestions ? how to get rid of it? Is it safe to remove it ?

When you do a clean install of Mac OS X, it creates a new system folder, then it renames the old System to Previous System folder.

To delete it simply launch Terminal and type:

sudo rm -rf

and drag the Previous System folder on the terminal to complete the path. Press enter and type your password. Wait a while, it deletes the old system and you've got all that space back.

If you've done a Archive and Install of Mac OS X, a folder with the previous schemes has created with his earlier Mac OS X system folder. Once you are satisfied that your Mac is working properly after an Archive and Install, you can delete the folder of the previous systems as follows:

Mac OS X 10.3 Panther or later:

1. Using your account manager, drag the folder of the systems prior to the Trash.
2. Enter the administrator password when prompted to authenticate this operation.
3. Empty the Trash.

Make sure you have copied everything you want to keep from the Previous Systems folder, including Shared folder contents. Follow the steps below as per KB TA22302 :
1. Log in with an administrator account.
2. Click the Finder icon in the Dock.
3. Open the Mac OS X volume. (This is usually called Macintosh HD, but could be named something else if you renamed it.)
4. Select the Previous Systems folder.
5. Choose File > Get Info.
6. Click the disclosure triangle next to Ownership & Permissions to expand this section.
7. Click the lock icon to see the owner and group options. Enter your password if prompted.
8. Choose the account name from the "system" pop-up menu.
9. Enter your account password if prompted.
10. Close the Get Info window.
11. Drag the folder named "Previous Systems" to the Trash.
12. Choose File > Empty Trash when you are ready to delete the folder.
