After I changed my ID # as described above I used:

$ sudo /bin/ksh # this is the shell I prefer
# find -xL / -user 56290 -print0 | xargs -0 chown 121826

This is much, much faster than having find exec chown a zillion times. Note, 56290 is ID # that I changed to 121826.

There’s more to do to avoid problems. I wrote an article covering the whole procedure:

I can’t believe that no one also added doing a ‘find / -uid 501 -exec chown 1000 {} \;’. Leaving that step out just leads to other problems.

I changed my uid to 1000 in this fashion and upon doing so, it no longer appears among the available accounts in the login window. Instead, there is now an “Other…” option that I have to click through and manually enter user name and password. Hassle, but I’ll live unless someone has an idea to fix it.

I’ve encountered some unexpected problems while following the above instruction in Snow Leopard (10.6.3).

Prior to the changes, my account was the only active account (root and Guest Account were disabled, no other accounts exist) and therefore my account was the Admin account. After changing my UID from 501 to 502 (really, I have a good reason for doing this) @cj’s instruction did not work and I could not back out the change.

I booted from the DVD and enabled the root account. Using root, I was able to execute @cj’s instructions and everything appeared to be fine.

Everything was fine until I tried to unlock the System Preferences. I get the message “You must type an Administrators name and password to make changes to System Preferences”. I also found that I cannot execute “sudo” commands. I expect that this is because I am not recognized as an Administrator.

My user name still has “Admin” underneath it, and “Allow user to administer this computer” is still checked.

I’ve logged in with the root id, and unchecked and rechecked the “Allow user to administer this computer” box. I have also run Disk Utility | Repair Disk Permissions. None of these has fixed the issue.

Any suggestions?

Thank you for this informations! Many of my NFS-problems are solved now. But I still miss the “Linux/Ubuntu-way-of-configuring” if I’m using snowleopard…

chown -R /Users/username is not sufficient: 1. It misses symlinks, and 2. If your main account is admin, your filesystem will be full of stuff owned by you. This should cover everything:

find / \! $ -fstype hfs -or -fstype ufs $ -prune -or -user 501 -exec chown -h 1000 {} \; -print

(replace 501 and 1000 with appropriate ID’s, and don’t forget the backslashes, they are important)

Remember to run the chown command afterwards, or you will not be able to access your home directory. Finally, log out and log in.

I use NFS to access files from two other Linux boxes and on each server my UID (unique id) is set to 1000. In order for me to easily have full access to my NFS shares from OS X I changed my UID to match
