Slow start-up, loud fan, programs not working.
My mac suddenly would not start-up as usual. It was extremely slow and the fan kicked in on high. Diagnostic check passed everything, so I don't think it is a memory issue. I have 80 GB left of hard drive space. Do you think I need a new battery? My hard drive icon is different also, as is the cd icon when I backed up files.
Is this a good question?
