I installed Yosemite 10.10.5 and Clover using a different system, because I think that's necessary for X99 with >7 cores. I can't get it to boot past the Clover screen. Here's what I've tried so far:
- BIOS enable EHCI handoff
- Add FakeSMC and VoodooTSCSync to the EFI partition, and also to /S/L/E. Change IOCPUNumber to 19 to match core count.
- boot args: -v npci=0x2000 kext-dev-mode=1
- set fakecpuid=0x0306F2
- replace VboxHfs-64.efi with HFSPlus.efi
- Brumbaer's IOPCIFamily patch
- PikeRAlpha's AppleGraphicsDevicePolicy patch (this seems to have no effect)

When booting from Clover, the screen goes black after AppleIntelCPUPowerManagementClient: ready. If I set nv_disable=1, then it boots to Yosemite.

Update: It doesn't always fail in the same place. Sometimes, the last line is AppleIntelCPUPowerManagementClient: ready, and sometimes it's something successful about Bluetooth. But in either case, the screen goes black and does not reboot.

Hooray! Changing SMBIOS profile to Mac Pro 5,1 allows me to boot with nvdrv_enable=1, and the performance is much better.
 
llamafilm, I don't suppose you could take the time to put together a really brief bullet point list of what you used in the end to get your system installed? I too have a Designare X99 board but with an i7-6900e, really having trouble getting to the OS install stage!

Actually, the posts in this thread pretty well document what I've learned so far. I'll put together a more detailed write up when I'm finished.
You can't install OSX on this machine. You need to install it using another Mac, then move the SSD over.
What's a 6900e?

Oh I see, I actually have my previous Yosemite install already on an SSD (this is an upgrade anyway), I can just plonk that into the new machine and update EFI/config as per the top of this thread?

Oh and sorry I mean a Broadwell-E i7-6900k! :)
 
That might work, but I suggest doing a clean install, because if anything goes wrong, it will be easier to figure out what has changed from the defaults.
 
Ah, installed the hdd on a different machine. I thought by "system" you meant technique :)
