Hello all, I've just fitted a new 500Gb Samsung hard drive into my Oct 2008 unibody Macbook, formatted the hard drive and then restored snow leopard from a recent time machine backup. Everything went fine except that there now seems to be a problem with the trackpad. I've lost the right click and 2, 3 and 4 finger commands completely. I tried unticking and then re-ticking these functions in system preferences but it hasn't made any difference. Does anyone know why this has happened and how I can fix it? Cheers, Don.
