I own a 2006 Black Core Duo Macbook, and I'm planning to sell it and buy a new Macbook Air this month for grad school. I've kept it in good shape, the Memory has been upgraded to 2GB, the hard drive has been upgraded to 160GB, and I bought a new battery recently. Unfortunately, about a month ago it started getting Kernel Panics pretty regularly. I brought it to the Apple Store, and after testing it overnight they concluded that it was most likely an issue with the video card. It will cost at least $150 to send it away and fix the issue. At this point, would it be better to send it away to get fixed before selling it, or to drop the price a bit and make it clear in my ad that there is an issue and include the report from the Apple Store when selling it? As is, the computer is usable, but depending on what kind of work it's being used for, it needs to be restarted pretty often. Aside from that, I'm planning to erase the Hard Drive and install a fresh version of Snow Leopard. Is there anything else that I should do before selling it?
