Hello all! Yes: I stupidly changed the short name of my home directory oblivious to the consequences. I have searched the internet high and low and have found a few threads already posted (including an Apple support article) that relate directly to this issue. However, although the root of the problem is the same in that I changed the short name, the outcome is slightly different and I can't restore all my preferences in the manner detailed in these articles. I have a Mac OS X 10.4.11. Here is exactly what I did and what is going on: 1. I went into Get Info. in the home directory icon in Finder. Say the original name was john, I changed it to Fred. 2. Since then, when I open any applications such as Skype, iTunes, iCalendar etc. all of the settings have been reverted to default making it appear as if I've only bought the Mac. -- However all my documents and music files are still there and can be accessed normally in the newly named directory. My desktop and widgets are also fine. 3. Now when I go to Macintosh HD and click into users there are 3 things: 1. The newly named home directory Fred with the house icon 2. A folder with the old home directory's name, that being john. Inside there are Documents, Library, Music and Pictures folders but only the Library folder seems to contain anything important, which I hope are all my preferences. The other three are effectively empty. Like I said I can access my music files etc. normally. 3. Lastly the shared folder. I haven't turned off or restarted my laptop because reading on threads it appears as if I can cause damage or end up not being able to access my mac. The two solutions I've found online are these: 1. http://www.thexlab.com/faqs/renamehomerecovery.html The problem with this one for me is that I can't rename the new directory with the old name - it just won't let me. 2. http://support.apple.com/kb/TS1876 The problem with this solution and another I found is that I think they are assuming the old directory - john - is in fact still a directory but in my case it is a folder. Apologies that I'm resurrecting a frequently posted issue but I'd rather be safe than sorry and I'm not exactly sure how to revert everything back to normal! Can I simply copy and paste the library folder from 'john' into a newly created user? How do I simply restore all my settings etc.? Any help would be greatly appreciated. Thanks!
