(Mac Pro) Tip for OS X 10.9 Installer Fails - No Drives Found
2 recent threads in Apple's forums from a couple 2009 Mac Pro owners (Mac Pro 4,1) said they couldn't upgrade/install OS X 10.9 because the installer couldn't access the hard drives for the install. (Failed on installer restart.) One affected owner reported removing the Wifi/Airport card solved the problem. (An EFI update to Mac Pro 5,1 didn't help.) No info there (yet) on what WiFi card model/chipset they had installed, but their comments reminded me of a similar problem with the OS X 10.8 installer on 2009 Mac Pros if an older (802.11a/b/g) Atheros WiFi card was installed. (Not very common since most use a Broadcom based 802.11n card (a/b/g/n) like Apple OEM'd with the Mac Pro. 2009-2012 Mac Pro Airport card is mounted on the motherboard behind the removable CPU tray, as shown in my 2009 Mac Pro article.)
If any readers had this problem, let me know what WiFi card was installed. (Check System Info.)
   The Tips page, OS X section has a link to the Oct. 2012 post on Mac Pro OS X 10.8 Upgrade problems due to (old) Atheros WiFi card conflict w/SATA. I'm guessing (from the 2009 Mac Pro/10.9 installer post) that the same issue is seen with OS X 10.9 for anyone with that older card installed. (And this may affect some other WiFi/Airport cards, not just the older Atheros (a/b/g) card noted in that earlier post. But again I suspect most 2009+ Mac Pro owners have the 802.11N Broadcom card, even those that did their own card install.)
