There are other reports of the same problem (I think in MacFixit) and it has been mentioned in the Apple Discussions. Open the Activity Monitor and see if something is taking up a massive amount of CPU cycles. Some have reported 100% (I think Update is one of the logical suspects here). Quit it and see if things return to normal. jg On 19-May-05, at 3:19 PM, J wrote: > I thought it was going to be OK but now the Ti/500 is overheating > and smells funny.......with little in the way of applications running. > > Files are backed up, now what???????? >
