Tip for No Drives Seen in Mac Pro by OS X 10.9 Installer
Saw 2 recent threads in Apple's forums from some Mac Pro owners (2009/Mac Pro 4,1) that said they could not upgrade to OS X 10.9 because the installer couldn't access the hard drives to complete the install. One affected owner said removing the Wifi card solved the problem. No posts there (yet) listed which WiFi card model/chipset they had, but this 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. Rare since most use a Broadcom based 802.11n card (a/b/g/n) like Apple OEM'd with the Mac Pro. (The 2009 Mac Pro Airport card is mounted on the motherboard behind the removable CPU tray.) Here's a link (from the Tips page, OS X section) 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 installer if that older card is installed. (But again I suspect most 2009+ Mac Pro owners have the 802.11N Broadcom card, even those that did their own card install.)
