This is a UK format keyboard for the 15" MacBook Pro Retina.
This does not include the back light sheet
Please Note:These keyboards are primarily held in by metal lugs instead of screws. This means the keyboard must be carefully 'prised' out of the top case unit before fitting this replacement keyboard. Where the lugs are removed, a keyboard screw set can be used to attach this replacement keyboard.
All the lugs can be removed, but it is not always a straight forward task.
you can find the screw set listing
