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

[Leesureone]

I can understand you're having difficulty with my confusion... So am I. I finally have an idea of what the EFI partition and folder do in the scheme of things. My problem currently is that I do not seem to have an EFI partition to mount with Clover Configurator. I mentioned using CC above. It did not list the EFI folder. I could not swap out the EFI folders as required. That is why I had put a Fat32 partition in one of my attempts to make a bootable drive. I since was able to re-partition it back to one partition. The

Well, I am almost good. The NUC8i7 is running Catalina with headphone jack sound, USBs, BT, and video etc. All is good except that it goes to sleep and upon me waking up the NUC with a bump on the mouse and keyboard, the desktop pops up and as I am typing in my password, the unit Re-Boots. It will reboot regardless of what I do. I put the EFI in a second time to hopefully ensure that I used the correct EFI. Nothing seems to work to stop the re-booting. I saw a post about USB configuration being necessary to fix a problem with sleep implementation. Should I do a re-config of USB setup? If so do you have the post or files? I am trying to find the post. The UUC seems to be running slow. It had a very difficult time expanding one of the Leesureone Zip files. I copied the file to the NUC sata SSD and it expanded in a flash. It took an unbelieveable long time expanding from the USB 3.0 TD.

So just to verify you are booting off the EFI partition on the hard drive now using Clover?
It does sound like your USB needs reconfiguring based on the sleep/ wake behavior. For some reason the NUC8i7s do not like the USBSSDT that works on the i3 or i5. Luckily it’s much easier to create your own and the link to the guide is below.

Important Update: June 2023 From Big Sur 11.3 on the built-in OpenCore XhciPortLimit quirk no-longer worked as described. This became a known "bug", though in reality it was Apple changing their internal code, making a simple "peek and poke" to keep it operating, a difficult task. However, with...

Hi Everyone,

I posted about this before but haven't really gotten anywhere with it. My Nuc8i7 works perfectly (airdrop, handoff, iMessage, everything) except for the fact that it just completely shuts off once in a while while I am working. It happens specifically when I am doing graphic intensive things, running flash sites, watching streamed content, or in a zoom meeting (happened this am in a work meeting). I noticed this start happening after upgrading to Catalina and it did not happen prior.

I thought maybe it is bad ram or something so I ran memtest and that checked out. Then I thought maybe it was a heat thing (fans are often really loud right before it happens) and read online about clearing out the fans. There wasn't significant dust buildup.

Right now, running one website with a flash-based form, and a couple browser windows open, here are my temps per HWMonitorSMC2. They do seem high. (90s C and sometimes I see 100 C). If I wait and dont do anything, I see the temps eventually drop to the 60s-70s.

Any thoughts?

Technical info:
Nuc8i7BEH
16gb ram
OC 5.7 using the folder from page 90. The only change is my serial number
SSD
Broadcom Airport WIFI card in M2 slot with the adapter (wifi works, dont have the cable for bluetooth)

Right now, just browsing the internet and with one flash-based page open.
Based on this, it isn't overloading the GPU that causes the problem.

This actually started happening on my computer and I got a replacement NUC from Intel and its still happening so I dont think its a bad processor/heat sink unless its 2 in a row.

Wow, that's hot, 100 degrees is supposed to be the maximum operating temperature for a i7-8559U CPU, no wonder its shutting down. Even 60 to 70 degrees is pretty hot and sounds like the CPU isn't throttling down like it should if power management is enabled. Are you sure you didn't change anything in the config.plist?

Question, do you have windows or another operating system installed you can compare operating temps?
You can adjust the fan behavior in the bios to run faster but that's a bandaid, its something else to cause to overheat like that.

Nope.. using exactly your config.plist and exactly your recommended bios settings. I just tried turning off the turboboost to see if that helps.
I have played with the fan settings but the thing sounds like a jet engine on the "Cool" settings.

I am thinking it is a hardware issue.
Dont have windows to compare.

You can run Linux off a flash drive, same for windows. Or swap out the sata drive temporarily...if it still runs hot then you know

Curious if you try Clover instead if it makes a difference...it shouldn't but it's another thing you can test. You can run it off a flash drive too.

I was running your clover install for a long time but recently switched over to OC.
The problems were actually worse with clover and are actually less frequent with OC. Now they only happen under load when I am using the computer but before just the screensaver would randomly trigger a shutdown.

I will try windows and see how it goes.

Dang. I'd like to hear what happens.

So I took the time to make a custom USB SSDT for the NUC8. I was preparing myself for a long evening but wow was that an easy job! The reading took longer then executing. I did it a second time and it took me literly 5minutes... And best of all it seems to work work very well:
- first of all, all usb ports still seem to function with a USB2 and USB3 drive (for test I copied a 2gb file from an external drive to the hack and it took 10seconds, so full speed)
- the hack goes to sleep perfectly fine
- when I woke it up (I let it sleep for about 10mins) all my BT devices connected fine
- after reboot BT devices working fine

what still doesn't work:
- I still have audio stuttering with my Bose BT headset sometimes (but I believe this is more linked to the headset, because in all honestely I had issues before on windows
- Tapp my keyboard/mouse/trackpad to wake it up from sleep (so same behaviour as with dongle), that's a bummer. But I'll investigate!

Attached:
- The sleepwake file, but I don't understand any of it.
- I've also attached the SSDT (both the dsl and aml, both can be opened with Maciasl). I guess it should work for everybody with a NUC8i7BEH(2)? Basically it limits your USB ports to 9 (so well below the 15 port limit)
HS01 - usb2 front right
HS02 - usb2 front left
HS03 - usb2 bottom rear
HS04 - usb2 bottom top
HS05 - usb2 internal1 (BT), internal2 not mapped
SS01 - usb3 front right
SS02 - usb3 front left usb3
SS03 - usb3 bottom rear
SS04 - usb3 bottom top

I have not yet enabled again the sdcard reader kext, which most likely is another port I need to map.

Let's see how the hack handles a full night of sleep!

I have been searching high and low to find your post. I have a NUC8i7BEH and it works fairly well including BT. I am listening to music on my BT speaker as I type. The Sleep/Wake ReBoot problem has been a fly in the ointment. I seem to suffer from USB dragging down the speed of the I/O also. My BT will drop out if I access the USB drive. It USB seems to be causing more than the ReBoot... I was wondering how it is going since your post is several months ago, which means you should have some experience or comments on the results of the fix. I am going to try the same fix and may see if I can drop your files into the appropriate spot. For me this has been a lot more than 30 minutes. I spent longer than that trying to find your post. Leesureone's EFI folder makes a good Audio result on my headphone jack. I haven't tried to hook up to HDMI yet. It works good except for the USB/Sleep/Wake problems. I am also assuming the fix will eliminate all my problems.
