I keep getting this message on my MacBook. The DVD drive doesn’t work, the battery doesn’t charge, the hard drives crashed twice and I had to settle with a 60 GB replacement drive, which would be great if it was still 1997. We’ve been through a lot together, but I think it may be time to put you to rest like a dog with a severe eye infection. Four and a half years is more than I ever imagined. I’m still going to squeeze every last bit of your processor. I love you computer.
