Hello!
first of all, thank you for writing up your guide, It has been a haven during my struggle of making my T5500 behave well.
QUESTION: do you have your video card in the PCI (upper) slot by any chance?
It seems my T5500 will comply best with the PCIRootUID=1 ....
although i'm still not sure if this is key to a successful install...
I think I have as much chance of succeeding
with or without:
PCIRootUID=1 kext-dev-mode=1
I'm using an nvidia Titan X in pci slot n:2. Second from below.
it is a maxwell card so its very friendly to macos x
(these were the ones that were supported before the 1080 etc. Pascal series)
I am doing a High Sierra install with apfs ssd format...
(apfs: because you have to move on at some point anyway.)
only the audio does not seem to work at all.
I got the LAN to work once.
I have done many reInstalls because sometimes my EFI partition was unaccessible...
I would advise to unplug every USB device and use your installer USB in the
rear ports, as the front ports are connected through a flimsy cable, and feel
like they are more likely to cause problems.
I also noticed, which might help people with trouble installing on this T5500;
that the drive system switched back to RAID from RAID/AHCI at some point.
Also, do enable hyperthreading, and speedstep, and everything! (except from VT-d of course)
because I only had 12 threads to my disposal before I realised this.
afterwards, a glorious 24 threads.
I use it for video editing. it is a bit faster than my i7 but i prefer Xeon stability
(the i7 on an asrock z97 board crashed on me a few times, also has no Ecc ram,
which ticks me off when converting big batches of video
)
anybody else golden tips for audio?
is the appleHDAdisabler supposed to go in the EFI partition or S/L/E?
is the latest version of voodooHDA (2.9d10 instead of 2.8.8) also good?
i just want it to function!! i'm using a usb audio thing and my OCD doesnt
like that workaround
