I am looking for a screwdriver or a bit that works to remove the battery in a mid-09 15" Macbook Pro. Instead of the typical tri-wing that Apple has used in the past, this screw is a 5-pointed torx with a post, requiring a special driver to remove it. It is a size-6 (TX6) bit, bit with the 5 points and the post, I cannot find a driver to remove it. Has anyone had success with this? If so, please share.
