Genuine Apple, version 2, UK three pin, 3A fused mains lead for white block power supply units/chargers originally shipped with the 2010 MacBook Airs and 2011 MacBook Pros, but compatible with earlier MacBooks, MacBook Airs, MacBook Pros, white iBooks and aluminium PowerBook G4s. This is interchangeable with version 1 cables but has a low profile mains plug and rubber-like cable. The modified figure of 8 connector forms one corner of the power supply block and completes its shape when connected. This lead is NOT suitable for the silver plug versions of the 45w iBook/PowerBook adapter as this contain the traditional figure of 8 mains socket which will not accomodate this lead.
