I am not sure if this is in the right area. Anyways, I just got a new iMac (Core i3) which came with the aluminum bluetooth keyboard. I installed Boot Camp, and wanted to use the Option key at startup to choose my OS. I found this doesn't work with the supplied keyboard. I tested this with an older plastic bluetooth keyboard and a USB keyboard. Both of those allowed me to use boot keys. Is this a known issue or perhaps something defective in the aluminum keyboard?
