Thank you! Here it is. https://www.dropbox.com/s/1y4o48agmz02av8/Send me newbillys-iMac-Pro.zip?dl=0 And this one. https://www.dropbox.com/s/bz2cdgf00jbikh9/newbilly’s iMac Pro.ioreg.zip?dl=0 And the original DSDT in case it matters. dsdt-from-bios.aml.zip

Now you have a minute of laugh. For tests I’ve redone the efi with your SSDT. Being tired of patching the whole DSDT for s3 mode (any bios setup change makes it crash) I made a binary patch replacing “_S4” to “_S3” and the data from 0x06 to 0x05 in DSDT. The latter was made with a typo and I had the hac fall asleep into S4! )))) of course it did not wake up, just started over. With S3 I have the very same behavior: sleep, then instant reset (in 1-2 secs) and BF post code (memory error)…

Sure Sir. It worked fine but there was no freq-on-demand power mgmt available (all the cores working on 1200MHz instead of 2200-2900), so I moved towards FakeSMC and some SSDT patches. In any case, was it your folder, or was it mix-salad, I could find no way to put the mobo into S3 sleep, it does not even declare it. However, as I said above, I could inject it into DSDT and only then get finally stuck... :)

Hi there. Quite a challenge that I gave up; maybe (hope!) you win. Ventura here, Asus z10pa-d8 (plain old C612 aka x99 chipset). NO SLEEP, EVEN NO OPTION IN BIOS. Only S4, no S3. What I've done. Sniffed around a lot, found out that some people do have bios hacks on Chinese x99 dual-cpu boards to have S3 working. Being a little not too brave to take a chance to brick the mobo, I tried to add this via ACPI. Extracted DSDT and put the _S3 part into it. That's all I've done, no sleep/wake routines patched due to lack of knowledge. The board now DOES go asleep but resets immediately, and the post code says Memory init error (0xbf). The question is: should I try Runme and post here, or there's guaranteedly no way in hardware (no refresh from 5Vsb etc)? I tried to boot windoze: S4 works as it should...

I had no serious success with files posted, went an own (roundabout?) way, now everything's working besides sleep (no idea yet, why) and wifi (intel ax201 board, no driver except pre-alpha itlwm kext which still fails to load). Can attach my /EFI if interested.
