Had an interesting issue trying to install\/upgrade to Mavericks on an Apple 4,1 Mac Pro Desktop.<\/p>\n

It was running Snow Leopard, but if I tried to install Mountain Lion or Mavericks it would give a disk error on reboot into the installer.<\/p>\n

I made a USB installer, booted off that, and could see that disk utility couldn’t see any drives inside the installer.<\/p>\n

As the equipment was working fine on Snow Leopard, this wasn’t a hardware issue.<\/p>\n

I updated the firmware on the machine to the latest version, but still the same issue.
\nCleared NV ram, same.
\nCompared SMC revisions, AHCI firmware revisions against a good machine, everything was the same.
\nChecked dmesg on the machine during a Mavericks installer boot, and could see that it was having issues with wifi, then with SATA.<\/p>\n

\"Boot<\/p>\n

I checked the other machine, and saw that it had a different wifi card. Bingo!
\nI removed the wifi card from the non-working machine, and rebooted back into the installer, and it could suddenly see the drives again.<\/p>\n

My conclusion is that the Intel ACH10 drivers, and the Atheros ARB5X86 drivers conflict with each other in 10.8 and above. I tested in the 10.10 beta too to be sure, and had the same issue.<\/p>\n

Something apple needs to sort out, I guess..<\/p>\n

Interesting issue, it took me a little while to troubleshoot.<\/p>\n","protected":false},"excerpt":{"rendered":"
