But 13" MBP mid-2009 have same spec with 13" MBWU late-2009, and higher end model have better cpu with higher clock rate
Why apple drop support on 13" mbp mid-2009? Its more expensive than late-2009 mb![]()
They dropped support on both the mid-2009 and the late-2009 MBP. Again, at a guess, because the 2010 MBP was the first one that didn't have the broken two-GPU-but-not-at-once architecture.
