Leoppard, I don't think the cpu issue can be solved, the cpus are not supported by the macos kernel. I swapped out the xeon 'e5-2367 v2' for xeon 'e5-2680 v2' as the cpu has worked in other builds. I did managed to boot to full macos gui but only sometimes, mostly it gets stuck at or just before the login screen, mouse pointer is very slow/laggy. I'll try a fresh install of High Sierra

cheers, I'll give it a try tomorrow, were there many edits/issues?

I picked up a server on ebay with 2 x e5-2680 v2 cpus (including a 1u case, intel motherboard S2600GZ, 16gb ddr3 1tb and 500gb hd) for £210 I installed the 2 new cpus in the Dell T5610 and the good news is there is no instant kp It was the e5-2637 v2 cpu causing the issue. I've attached the clover f4 dump with the new cpus, does the new extract need any edits to get it running nicely? origin.zip Doug

I did a search to find out if the Dell T5610 has had any successful installs, seems it has been done before, there is a write-up on insanelymac https://www.insanelymac.com/forum/topic/331372-write-up-installing-os-x-1012-sierra-on-dell-t5610-dual-xeon-uefi/ Next I searched for installs using the e5-2637 v2 cpu, didn't find any but did find people are getting the same 8 threads should have 9 type issues so I think it's a cpu issue. I planned to get a pair of e5-26xx v2 xeons anyway so will research known working builds for the e5-26xx vs series. Once I get the install usb booting and mac os installed I might need some help with getting is running nice, eg renesas usb3. Doug

I used the clover files from the x79 series, i'll reformat the usb drive and try the options you suggest. The macos version I used is yosemite as I thought it should give less issues. Do you think the version of clover could be an issue? I'm sure this must be fixable as the chipset is very close to mac pro 6.1 Will try tomorrow Thanks again

Thanks again for your help. Still counting the wrong number of threads see pic attached. Added in 7 minutes 29 seconds: The chipset used in the Dell T5610 is c602, which is an upgraded version of the x79, the mac pro 6.1 from 2013 used the c602j chipset. IMG_6092.JPG.zip

Thanks for your help. I did a fresh dsdt extract (f4 from clover), dissasenbled with refs.txt and opened dsdt.dsl in rehabmans latest maciASL, pasted in your code fix, compiled with no errors, saved as aml. I copied over the file to the boot usb. Booted but still get kp I took a video as it flashes past too quick to read. kp is "x86_validate_topology() 8 threads but 9 registered from MADI"/BuildRoot/...." Here is my clean dsl extract from F4 in clover origin.zip

I have the same issue, kp tho I only have 4c/8t, panic is "Should have 8 Threads, but only found 9 for die....." Back story...I have been using my Dell T5500 workstation (dual xeon x5675/64gb ddr3 triple channel/gtx680) for a while with no issues, but it's now 10 years old. Recently I got a newer model, the T5610, it can take 2 x xeon E5-26xx V2 CPUs (Ivy bridge era) x79/c602 chipset, USB3. I only have one cpu, the E4-2637 v2, 3.5GHz, 4core/8thread, Win10 runs fine. So I tried a clean install with your clover x79 series but get the kp. it seems to be counting 9 threads instead of 8 and you have 33 instead of 32, others have 17 instead of 16 so seems like a math issue, always one extra. see pic below: Capture.zip I plan to buy 2 xeons for a dual setup, not the E5-2690 V2, they cost $450 for 2.
