I would like to thank everyone that has contributed information to this thread (especially eng_mat, the OP).
Because of you I have a fully working Mac OSX 10.9 (Mavericks) installation going.
Can't get the 540M to work but that's allright.
I learned a lot along the way, when I started didn't even know what kext files were. Without this thread I would have been hopefully lost.
For everyone that needs the Wifi drivers for Atheros AR9002wb-1ng, look here: http://www.osx86.net...less-half-size/
Can't thank you guys enough, Mac OSX rocks!
@flitskikker I have an N53SV - SZ404 and 10.9 is rocking solid so you can try too I guess.
FYI I didn't use the Kext the OP provided but used the Intel 3000 ones that were installed with Mavericks.
