screw came out of the bottom of my MacBook pro
One of the short tiny screws on the bottom of my MacBook Pro came lose and is now gone. Since 2011 (when I got my mac) I've had to periodically check the bottom screws to make sure they were secure and now one has come out and is lost. My question is where can I buy new screws and what size are they? I already have and use a #00 Philips screwdriver from a sewing machine to screw them in.
