In the film 1988 "Childs Play" there was an evil doll call Chucky who kept coming back to life even after being killed... Mac problems seem like that sometimes. A quick read of any Mac troubleshooting forum and there are stories of a problem that went away for a couple of days and then came back. As a Windows technician primarily, bar the odd recuring Blue Screen of Death - a "fixed problem" usually stayed fixed. Not so with Macs. Sometimes they will give the appearance of being "fixed" but then start playing up again maybe 4-5 days after. This is one aspect of Mac troubleshooting which I have not been able to figure out. Can anybody explain this one?
