Cassandra: Apple Serial Numbers - The "O" is a Zero
By Graham K. Rogers
One major part of my preparations was of course multiple backups of the MacBook Pro using Time Machine, separate disks for the photographs in Aperture, and copying some data to the Mac mini that is doing sterling work as stand-in.
About This Mac (with some identifying data removed)
On Tuesday evening (just before uploading this file to my site), I was phoned by iCare: the Mac is ready. That took just 5 days, including the weekend. The screen itself has been replaced: another good argument for AppleCare. Without that, the computer would have been several months out of warranty.
You can find your serial number for your Intel-based iMac (Mid 2007 and later) in OS X, on the base of the computer, the product packaging, or on your original receipt or invoice.
AppleCare registration numbers and Apple hardware product serial numbers sometimes include the number "0" (zero), but not the letter "O".
This is something that often confuses me when registering software or other products, but as far as Apple is concerned, there is no letter "O", only a zero.
