Just a quick question..I have a apple wired keyboard hooked up to my iMac through a USB extender cable. I have some problems with it however. They are: 1) When I boot up my mac, I have to plug the keyboard directly to hold option so I can choose what disk to boot into. Is there anyway I can fix this? 2) When I use a wired mouse connected to the keyboard through the extender. I have to unplug and plug the mouse back in for OSX to recognise it.. Any thoughts? Thanks.
