OK, I scored on a Refurb and it's a 27" iMac... RFB IMAC 27"/2.8QC/2X2GB/1TB/5750/SD-USA Refurbished iMac 27-inch 2.8GHz Intel Quad-Core i5 processor The file transfer could not have been easier. I restored from a Time Machine external drive back-up. SO EASY!!! Anyway, here's where I need help. The 21.5" I am keeping for my spouse. I've decided to not wipe out the hard-drive and to just change the name. I've figured out how to change account name, the mouse name, the keyboard name, etc. But what I am having trouble with is the home directory. I found this: http://support.apple.com/kb/HT1428 But when I got to step 4 it wouldn't let me change the name "just like you would rename any folder". I select the home directory and hit Return but it just beeps and doesn't open the name for editing. ANY IDEAS???
