So I learned the hard way (the hard way being my MacBook Air locking up right before when I get on stage to present), that .Mac and the UK just don’t mix. The SyncServer process seems to run the CPU cycles up, taking up to 99%. I kill it and it would keep popping back up. So far it has locked up my MacBook about a half a dozen times in just three days.

Daniel (who is UK-based) mentioned that he has suffered from the same problem on his G4 PowerBook. I wonder if there is an issue with connecting to the .Mac servers while overseas?

Note to self: turn off iDisk and .Mac syncing before heading to the UK again.
