Hi guys, My macbook is driving me mad tonight, the fans on them are going crazy up around 6000rpm when it's not doing anything and no apps are open. I tried repairing disk permissions but that doesn't seem to have done anything. For some reason about 50% of my cpu is being used for nothing. I tried resetting the PRAM but that hasn't done anything either in fact now it won't even pick up my wireless network. I thought it could be linked to the latest update to leopard as i read some other posts about that but it's been happening for a few days now. I would really appreciate it if anyone can help at all, i'm due to go to austria next tuesday for my wedding and want to take it with me. thanks for any help in advance.
