Up until yesterday Apple stated that PowerNap would work with MacBook Air models from 2010. Now all of the sudden it's 2011 MacBook Air or newer. Something ain't kosher here...
You're right !!! I am the owner of a MacBook Air 11'' Late 2010 and I am 100% sure that Late 2010 MB Airs were supported by PowerNap until yesterday, f...k you Apple !!!
