Macbook multi-touch functionality with LION OSX
I know that some of the older MacBooks (2006-07) have multi-touch trackpad. Are some of those models only one or two finger touch? I am wanting to upgrade to Lion OSX and want to make sure the trackpad will support three and four finger gestures. And which is the oldest macbook model that supports multi-touch and will support all the functions on OSX LION?
MacBook, Mac OS X (10.7.4)
