When I saw the new Apple keyboards I knew one had to be mine. I'm a huge fan of my MacBook's keyboard, and the new Apple keyboard is a MacBook keyboard you can attach to any number of Macs, what could go wrong?
Once I got my new keyboard in the mail I set it up on my iMac. I downloaded the Keyboard Software Update, restarted the iMac, and plugged in the keyboard. All the special keys worked as they should, with the exception of the Exposé key and the Dashboard key (F3 and F4). Press as much as I would, these keys did nothing. I thought that it might be the iMac, so I repeated the steps on a MacBook Pro and a MacBook with the same results (I also tried using different accounts on those machines, to no avail). Luckily, this isn't a hardware issue since the buttons actually work (I assigned some shortcuts to the F3 and F4 keys to make sure they were actually working) so it would seem the devil is in the software.
TUAW reader shak forwarded a link to this Apple Support Discussion in which several other people are encountering the same problem. Do not be fooled by this discussion's 'Solved' status, as reading through the discussion makes it clear that this problem is being encountered by many folks.
TUAW readers, is anyone else out there seeing this behavior? As I wait for Apple to fix this issue I'll be reading the comments here hoping someone has a solution.
