How do I get rid of a Mac user acct w/o losing files?

July 21, 2009 4:35 PM

I have a MacBook Pro running Leopard. It has two admin accounts. Some time ago I stopped using account "A" in favor of new account "B" (the reason behind the creation of account B isn't relevant to this question, however). If I delete user account "A," what precautions must I take to ensure the preservation of the files created under "user A," and what automatically happens to the ownership of those files?

When you delete a user via the Accounts option in the System perferences, you are given three options

- archive the user stuff as a disk image in a "deleted users" folder
- do nothing, save all the stuff where it was
- delete it all

These are three very clear options and you can pick one if you go this route for deleting the user. Since you're an admin on both accounts, you can easily copy those files to the B account before deleting, or you can still access them if you go the second route.

what the screen looks like when you try to delete a user.

Jessamyn- Thank you. I am still not sure what happens to ownership under those circumstances, though. if I don't change the home folder, the files are just sitting there "orphaned." Do I have to give Account B read/write permissions for all of these files?

I believe the files that were owned by A will be orphaned once you delete the account, but as long as you have account B, you can modify the permissions as necessary after the fact.

As an admin user, you can change the ownership of those files either before or after deleting their current owner. Just open the Terminal and type "chown -R `whoami` /Users/userA" (replacing "userA" with whatever user A's short name is).

Yeah, if you're an admin you're essentially root and can change the permissions to whatever you want. I usually go to the main directory, choose "get info" and then change all the permissions and make them recursive down the file structure.

You might also try using find plus chown to locate and re-map the ownership to B. The command you need is something like this:

$ find / -user userA -exec chown userB {} \;

The backslash before the colon may be unnecessary. This will find all files anywhere owned by userA and change their owner to userB. Obviously this will only work when run as an administrative user.

I would say do not delete the other Admin account. It can be used to verify problems with the current account.

@axiom: you do need the backslash before the semicolon, or else the shell interprets it as separating the find command from a subsequent one.

@Cogito: Thanks. I suspected it would be, but not having a Mac I could try this out on, wasn't sure if maybe those kooky apple people decided to use some other character as the escape or something.
