Hi everyone, thanks for all your input and feedback, I've been reading your replies with attention. Warm thanks again to RehabMan for sharing his work, early on!
With the update of Mojave 10.14.4 available on Monday, I decided to risk and do an exercise, as the NUC8i7BEH (or BEH2? not sure) that I have, is still under "setup mode" and experimentation for learning.
I hope I can get
@RehabMan to comments on this, I know he's busy, but it's an interesting find.
So I was OK under the setup of RehabMan's repo and code; I had changed from his iMac16,2 to Macmini8,1 to see what happens with CPU power management, last week. I saw spikes that I didn't understand in Intel Power Gadget (latest=v3.5.5) while monitoring "idle".
This Monday, I updated to 10.14.4 without hiccups. Rebooted like 3 times. Using NUC8i7BEH with 2x8GB HyperX RAM and a test Kingston SSD 128GB. No NVME yet (I see the 970 EVOs are disappearing and getting expensive, whie
Plus is staying; got to get my hands on one, fast).
BIOS was thankfully
downgraded last month to v56 after catastrophic update to v64. But I read v66 or newer works again, please confirm?
So I decided -for learning- to remove all kexts, all Clover stuff (including
all AMLs from patched folder) and make it totally vanilla.
Guess what? With 2 kexts and
basic Clover config.plist, the system boots, is fast and with a surprise. No audio installed yet, all WiFi/BT/SD-Reader
internally disabled etc. Don't have Thunderbolt to test, set it to "Legacy" in BIOS as advised in another NUC forum.
So I removed everything and left the following:
The needed LAN driver
IntelMausiEthernet.kext and plain
FakeSMC.kext (no plugins) to /Library/Extensions/ and a
basic config.plist (including renames of devices) in Clover EFI. For kexts in Clover, just left a copy of FakeSMC to be sure I can boot. Rebooted system. Seems the
Intel 655 Iris is now natively detected, did
not need Lilu or WhateveGreen kexts!
I ran Geekbench... the IGPU scored
55402! CPU was around 19820. On Idle, temps are around 37-38ºC
The moment I installed Lilu.kext v1.3.5 and the
just released WhateverGreen.kext v1.2.7 and rebooted, the Geekbench for IGPU (without any modifications to config.plist, just let it auto-detect)
fell to 34532!
I still have to keep adding stuff up to get HDMI and Realtek audio via FakePCIIDs but so far, system is amazing stable.
-No sudden reboots after 10-15 minutes.
-Still under Clover_v2.4k_
r4895 and SMBIOS as
Macmini8,1.
-On 10.14.4, the 300-series SATA is still not recognised, shows "Generic".
-Booting again gets stuck mid-way, with a seemingly pause, I just don't get it. High Sierra is so much better.
-The HDD LED, despite set active in BIOS, just works intermittently. What the heck.
-USB ports in IORegistryExporer are all shown, no evident need for USBInjectAll (yet). BIOS at default settings for USB.
-Without WhateverGreen, I get a temporary pink flash when booting switches resolutions prior to entering Desktop, while with WhateverGreen 1.2.7 this doesn't happen.
What I must be sure of, is to get audio via FakePCIIDs and FakePCIIDs_HDMI to be injected, will gradually add them as at some point I had the “sudden reboot” and need to find the culprit.
BIOS settings are basic as mentioned in the thread (after defaults) I even removed "Legacy Boot" to test behaviour (and now still without Legacy Boot).
What I would like to get, and did not have even with RehabMan's code/files, is the HWMonitor.app stuff, proper temperatures, fan speeds etc. Not sure if the available old FakeSMC plugins work with this hardware
So for Audio, as a next step, need Lilu.kext and AppleALC.kext for detecting Realtek and FakePCIIDs and FakePCIID_Intel_HDMI_Audio kexts for HDMI audio. On my hardware, Audio ID=28 worked.
Will report back, but this is an interesting find. WhateverGreen slows down the IGPU... I have no idea why.
P.S. GPU Acceleration seems active, but playing YouTube HD video on
Safari (while running Intel's Power Gadget to see IGPU behaviour) showed issues on Safari and LIVE streams. Recorded ones played fine. Probably a
DRM issue already reported somewhere.
On Chrome v73, France24 or SkyNews both HD Live, for example, started straight away, while Safari was keeping trying all the time...
Hope RehabMan can comment on these findings, I post the
config just to show it's plain...
