I live in a part of Greece where there are a lot of earthquakes, and it frightens the crap out of me since I have never experienced one before I moved here in June of 08. The other night, I was sound asleep, as was my iMac, then a earthquake started, and my iMac woke up, and at the same time, woke me up too with the bright screen flickering on. It was a minor earthquake, but it gave me enough time to get out of bed and get to the front door, just in case. Given the such superior thinking power of my iMac p), I have a question. Is there any way that the iMac can also play a sound when it wakes from sleep, so it can really be beneficial to me?
