Yeah, OSX is good but it still has problems.
. chooses 2.4 over 5
. not automatically connecting to my mobile wifi even though I use it all the time
. simply tries and fails to connect over and over and over .. I have to stop wifi and start it, and then it just works.
My 2013 Air has had three updates including firmware that mention wifi fixes but it still has problems.
OTOH, my Fedora 20 install has been behaving beautifully (though to be said in far less challenging environments)
