[Guide] Intel NUC7/NUC8 using Clover UEFI (NUC7i7Bxx,NUC8i7Bxx,etc)

I used Leesureone's updated clover EFI on page 90.

I was able to get the install working. So far the obvious stuff works (keyboard, mouse, internet, display). However, when I put the computer to sleep it reboots on wake. I tested it with and without my eGPU attached so it does not seem directly related, but I do know that the eGPU can affect sleep. I also tested with and without "put drives to sleep" in the settings. Any tips or guidance is appreciated. I posted my computer specifications below, please let me know if any other information is required. Thank you again for your time.

Computer Specs
Intel Nuc8i7beh
i7-8559u
240 Gb SSD (Used for hackintosh)
1 TB M.2 (Used for another OS)
2 x 8 GB 2400 Mhz DDR4
RX 590 Routed through TB3 eGPU.
Sleep/ wake failure is usually a function of incorrect USB port limit configuration or a USB device plugged in that is keeping your computer from sleeping similar to your Egpu. There have been quite a few i7beh users reporting the same behavior that solved it by creating their own specific UAIC-SSDT.aml.
 
Thanks for the Quick Response, I hadn’t found anything either, it’s another NUC8I3BEK, same as the last one. The previous one I used your same EFI folder and did Mojave and that worked. Perhaps I’ll try your OpenCore install instead.

Thanks again for trying.
Did you download the latest clover version?
 
Hey @Leesureone your Post #90 worked very well for me, I'm now on 10.14.5. I tested it on a blank hdd, which worked on first try. Now on my main system, after every reboot or coldstart I get the message that the Mac was shutdown due to an error. The system is stable, but on every start I get that output. Thanks in advance and everyone stay save and healthy.

Did you download the latest clover version?

With the Bios 71 I used your EFI folder with Mojave, then Yesterday I saw you updated it again so I downloaded the new one for Catalina. Im working on downloading your Opencore one now. I'd respond faster but it seems Tonymac has blocked my IP from connecting to the Site for Some reason, the only way I can get to it is through a VPN, or on my Phone.
 
Hey @Leesureone your Post #90 worked very well for me, I'm now on 10.14.5. I tested it on a blank hdd, which worked on first try. Now on my main system, after every reboot or coldstart I get the message that the Mac was shutdown due to an error. The system is stable, but on every start I get that output. Thanks in advance and everyone stay save and healthy.

Hi @schlotterp, great to hear form you again. Question, did you update Clover, WEG and Lilu prior to the 15.5 (which is beta right?). I've updated everything to 15.4 successfully now but beyond that build I don't have any experience.
 
With the Bios 71 I used your EFI folder with Mojave, then Yesterday I saw you updated it again so I downloaded the new one for Catalina. Im working on downloading your Opencore one now. I'd respond faster but it seems Tonymac has blocked my IP from connecting to the Site for Some reason, the only way I can get to it is through a VPN, or on my Phone.
Okay cool. I got blocked before as well and I think it was because I linked to some content outside the site that didn't satisfy the forum rules. Not really sure the reason, no notice was given.

I'm still alive.

My mistake, I meant that I've updated successfully to 10.15.4 (Catalina). Clover Configurator is on 5.9.4, Clover Bootloader is 5108, Lily on 1.4.2 and WEG 1.3.7.

Okay. It looks graphic related, the backtrace seems to point to that, but frankly I really do not know. I have an EFI folder on page 90 that works on my nuc8 you are welcome to try. It doesn't have Fakepciid or intelfake hdmi kexts but I know you can add those if it works for you. I also found using Rehabmans original scripts still work as long as you update kexts, clover and remove kexts installed in L/E and also rebuild the kextcache. It did for me anyway.

OK, So we have some progress.

I started over... I set Bios to Defaults, I wiped the USB stick, re-ran unibeast, Put Catalina 10.15.4 on the Stick and overwrote the EFI folder with the one you provided. Still nothing worked, it froze at the exact same spot. I thought to myself I wonder if its the USB stick, It was cheap 32GB stick and only USB2.0.... The only USB stick I have thats 3.0 is a 256GB stick and Unibeast will not work with it because it's "Too Big".

So I created the stick manually, used the old createinstallmedia file from within the Catalina Installer, then manually put your EFI Folder onto the EFI partition on the USB stick. Now, THAT stick allowed me to boot into the installer! It ran through its initial setup after the 1st time, then 2 more reboots as per my usual experience with the Installer.

I am seeing a lot of the following errors during the bootup process which make me question the power settings (Even though It works great on my other Nuc's, but i never allow sleep for these systems)

"AppleBusPowerController: AppleBusPowerController: requestStaticServicePowerLocked: power supply unavailable, assuming successful power for SS01 of 750mWakePower and 0mwSleepPower
AppleBusPowerController: AppleBusPowerController: requestStaticServicePowerLocked: power supply unavailable, assuming successful power for SS02 of 750mWakePower and 0mwSleepPower
AppleBusPowerController: AppleBusPowerController: requestStaticServicePowerLocked: power supply unavailable, assuming successful power for SS03 of 750mWakePower and 0mwSleepPower
AppleBusPowerController: AppleBusPowerController: requestStaticServicePowerLocked: power supply unavailable, assuming successful power for SS04 of 750mWakePower and 0mwSleepPower"

Basically though, I WAS SUCCESSFUL in installing Catalina! It's been up for a whole 10 min and seems like its working pretty well.

EDIT:

It is up and running, but has Panicked a few times on me, and the Ethernet connection is super unhappy.

It's strange the system is MORE stable with the USB boot drive, than it is Using the files off the HDD.

The only thing I did was use Clover Configurator to Set the Serial number and UUID of the system, and copied your files directly.

If a USB drive is too big you can always partition it to 16GB and a second another partition of whatever size is left. I have a bunch of 32 GB drives I use that way all the time, the partition without the OS X installation files I use to store other versions of EFI folders, Clover Configurator, and whatever else. I have an M2 Sata Hard Drive that's 128GB I partitioned the same way. I put in a hard drive type case/ adapter and connect to it using a SATA to USB3 cable and it is 10 times faster loading it and installing.....I'm just saying drive size bigger than 16GB isn't a problem.

Meanwhile I have no idea why an identical box and configuration would be acting so differently. Bad install? Seems wired though.

This guy said he had the same problem:
