I've been using Mac's for over 25 years. Had all sorts of problems. Most I lived with until I got a new machine, as I didn't feel like going to a mall to the Mac Store, which is a lot like Starbucks without the whipped cream. I also need my Mac back sooner than a month.
I just had something major happen to my main machine, and spent nearly two weeks getting things back in order. Replaced both hard drives, reinstalled system software, restored files, etc. It was a combination of a hard drive going bad, corrupt files, and I think a virus. It came on quickly.
