Toe said:Judging by the picture on the description page, it sure looks like this is a basestation update. however, under system requirements, it lists "Mac OS X 10.4.3 or later and AirPort Extreme Card" which implies that it is an airport card update.
I just ran it on my iMac G5 (which has no Airport), and it did install... but it didn't change the Airport Admin Utility, nor does that utility offer any updates to my basestations.
So I guess it is a card update. As best as I can tell, it is for compatibility with AP cards under 10.4.3 and some 3rd party wifi stuff.
Software Update showed the update but it wasn't ticked.
Installed fine on my old iBook with the original (802.11b) AP card.
Also, you think they could have waited a few hours or so and rolled this into 10.4.3? You know, for all the uptime nazis out there.
