This happened a little before work this morning so I've not really had time to check it, pull out batteries or the usual bits and bobs. It's a Macbook Unibody 13" about 6 months old. I'm assuming this is unrelated, but I applied the Safari Update this morning, restarted and now my Macbook won't boot. The Mac reboots, plays the welcome / boot tone thing, and on the grey screen (prior to apple symbol) starts beeping continually; 1 second beeps (approx) Can anyone help me out? Going to go home via the apple store but didn't have a chance to pic up my macbook before I ran out to work.
