My NUC8i7 has been working well with Leesureone's EFI folder. The only issue ever since upgrading to Cataline, I have been having times when it randomly fires up the fan on full blast and then shuts off completely. I have finally identified that I was having horrible overheating issues. I just installed HWMonitors and it looks like just opening a couple browser windows open or with VMWare fusion open the CPU temps are over 95deg C. Its a fairly new device so not like it would have a bunch of dust. Any thoughts on this?

Edit:
For reference, I have only 1 browser window open and CPU cores are at 100 or 95 degrees C. This is with tweaking the bios to limit heat by turning off performance settings.

The NUC's have a terrible reputation of running hot like ultrabooks. The i3's are not so bad but I have the i7 like you and in windows 10 the fans would spike like that. It is the turbo boost feature which gives high clock speeds for short periods of use. Thing is just browsing sets it off and I see 100 celcius regularly.
Go into bios F2 and click advanced. Then go to cooling tab and change dropdown from BALANCED TO QUIET as the option and it will keep the fan and cpu spiking like that. This is the official suggestion from INTEL btw. Search google "intel Nuc8i7beh high temps and fan noise" and you will find a LOT of posts on it.
The reason for the change in Catalina is I'm guessing turboboost was not working in Mojave as your CPU was not identified properly or something like that. The other reason is you might have updated your bios for the upgrade and they changed thermal and cooling defaults on the later bios'.
Now the other thing is every 12 months or so you have to clean the fan as it fills with dust.
IMPORTANT TEMP AND CLEANING INFO: The nuc's have a fault where dust gets caught between the fan and the heatsink on the cpu. Your CPU should be around 35 celcius when idle and nothing open. if you notice your base temps high all the time then you need to do the clean this post suggests. The NUC9's specs have been leaked and they have at least put TWO fans to cool the CPU's and better copper heatpipes so I hope they fix this.
You will start to have lockups and video stuttering etc when your cpu is too hot all the time.

They do but from what other users have said they had to rebuild their USB.SSDT so they would work. The weren't included in the build Rehabman started for us but Sakuri has these versions on his Github page. He runs the internal wifi/bluetooth in his M2 slot like you are. I've attached his ACPI\patched folder, just replace the contents of yours after backing up, hopefully it does the job for you.
I continue to be amazed at your knowledge.

My understanding is not without modifying the SSDT that patches which USB ports get used, Rehabman wasn't using them so they weren't included initially. I uploaded another users ACPI/ patched folder that should enable them.
I have downloaded your changed SSDT. I'm still getting my head about editing SSDT and config.plist very complicated. Trying to reverse engineer the files that make our NUC's work. Time consuming. I realise without the initial work and your keeping things updated when a patch breaks things we are in trouble.

Haha, said it before I'll say it again, you sir, are a scholar & a gent. Just used that patched file and replaced the contents with it and bang now my 2 port USB NUC lid is now working in Mac OS. Thanks!!
So it was the serial number causing the problem or was it the updated kexts that fixed things for you?

No help for my random shut downs and high heat? I took the whole thing apart and checked for dust buildup in the fan assembly (read about that on other threads) but there was none. I actually think it’s some kind of software issue. No one else is having this problem?
I replied to sakiv's post. His issue is to do with turbo boost. Way to fix it is change cooling profile from Balanced which is default to Quiet it makes the turbo boost and fan noise more conservative while not effecting temps. Do this Bios change first.
Boot your NUC. let it load everything and wait five minutes. Make sure nothing is open ie no triangles under your dock icons right click and close everything. Make sure to have rehabmans fakesmc hwmontioring kexts in the kexts/other folder so you can see cpu and other temps. download them from latest file here. Drag the hardware monitoring app into applications folder.
If your base temps are at idol 35 to 40 celcius then your temps are ok. You will get spikes in temp up to 95 celcius if browsing the web etc that's normal. If that is ok then your problem is possiblly hardware related ie memory related but worth making sure base temps are ok first.

Hi folks, yes I know, I'm probably going to catch some slack for this, but...
I couldn't get my M.2 broadcom wifi/BT card working in Catalina, nor the accelerated graphics. So...

I did a fresh install and went back to Mojave.

So, I used the EFI folder from this forum (latest from reposted #1582, Sevift package for NUC7) Got it to boot, but guess what? Same issues :O

No Wifi/BT, and no accel. graphics.

So, I guess I'm back to square one, but with Mojave. Just a note, when I used Rehabman's original process way back when, at least my wifi/BT card worked (don't remember if graphics worked). Not sure what the delta is, so maybe some help there would be great. I didn't run any of his scripts, etc for this new build, so I don't have any conflicts in kext locations. It's all clean.

Any help appreciated at this point.

Firstly the NUC7 EFI doesn't have support for the wifi/bt card that is something extra. Make sure to update your kexts that should fix your cpu identification.
Use Kext Updater it is very simple and puts the new kexts in a folder kext-updates folder on your desktop. Just copy them to your kexts other folder.
Here is the link for the kext updater software. Really easy to use.

Now @HedgeHog2k just got his NUC8 working for the M.2 wifi/BT working and the kexts and additions he should help you with. Wait for him to post. I think he used this guide but he might have updated info. He is using Catalina I know that.
Here is the Guide that for wifi/BT have a read to see if anything is of use until Hedehog2k posts. https://github.com/sarkrui/NUC8i7BEH-Hackintosh-Build or @Leesureone might be able to help.

Just to make sure you are using the NUC7 efi from this link:

iMessage is still not functional, i ran out of time last night to redo serial numbers.

HDMI issue - still to early to tell but after updating both kexts i've not had a repeat of the issue.

Extra USB ports - Now fully functional after using the PAtched file that Leesureone posted.
