I changed computers so I am selling this lock which is no longer used. The lock is great for when you want to leave your MacBook unattended in a crowded or public space. It works with 15'' older generation retina models. It is as good as new, and it comes with two keys, screwdriver, and cable. I am asking for 30 but will end up selling to the best offer.
