Okay, so here are the issues (all of the following happened with both apple pro and third-party hardware): - About 70% of the time when my mac boots or comes back from sleep it won't recognize the first (and sometimes second) letter I press on the keyboard. (Makes typing passwords a real pain in the butt ) - It also goes through brief periods where I will have to unplug and plug back in the keyboard and mouse or the mac won't recognize that they're there. This happens mostly when booting and returning from sleep. - Finally, sometimes when I boot from a CD the mac won't realize that the keyboard or mouse are there at all and I have to hard restart. On a separate note (maybe related, I don't know), my apple pro keyboard has issues with double typing all the time. BTW, I know that it's not me, since it only happens when I am on this computer. Any thoughts on what could be going on with this would be greatly appreciated. - reaper BTW, I have a MDD D1.25 FW800, 10.3.3 (let me know any other specs that would help). Thanks again!
