SET 1: This is a set of base screws for a MacBook Late 2009 – Early 2012. If your MacBook is white polycarbonate and has a big rubber base rather than four feet then these are the right screws.
SET 2: This is a set of base screws for a MacBook Air 2010 – 2015.
SET 3: This is a set of base screws for a MacBook Pro Retina Models A1398, A1425 and A1502.
SET 4: This is a set of base screws for the non-retina MacBook Pro. They have the optical drive and MacBook Pro on the glass at the bottom of the screen.
If your MacBook or MacBook Pro has a split base with user removable battery then we do not have the screws for those. If your MacBook Pro has silver keys these are not the right screws either
You can get the age of your computer model by clicking on the Apple logo in the top left corner of the screen and selecting “About this Mac”.
You need to have a P5 Pentalobe screwdriver for the Air and Retina screws. The MacBook and Non Retina Macbook Pro are small Phillips
These are great if you are missing some screws. I have seen people holding their machines with masking tape, electrical tape, sellotape and even bulldog clips!!
It is certainly way better than a having a loose base.
