  1. Sierra 10.12 on HP XW8600

    Hello Blaggah, thank you for responding. As I said, I followed the guide as close as possible and used the kexts and DSDT.aml from the first post. Still, my disks are not recognized in the Sierra installer. I don't understand why my xw8600 behaves differently than yours. In the meantime, I have successfully installed Sierra with Enoch. Could the BIOS version make a difference? Does the DSDT.aml possibly not fit my system?
  2. Sierra 10.12 on HP XW8600

    I also have a HP xw8600 workstation currently running El Caption with Enoch. When I discovered this thread, I immediately thought I'd give it a try and switch over to Sierra. I followed the OP's guide very close and made a USB installer with a certain tool from a freshly downloaded MAS version of Sierra. Everything seems to work fine, except I cannot see my disks neither under disk utility nor diskutil. I changed the SATA emulation mode to RAID+AHCI and installed AHCIPortInjector.kext, but still no luck. Under El Capitan, my disks are recognized in AHCI mode. I'm using the OP's DSDT.aml and my BIOS version is 1.46. Any help would be appreciated.
