I tried reinstalling and using other serial and data (with the coverage message too) with same result, can't log in the account. Too many problems and wasted time, I throw in the towel, but thank you very much for your help!

Yes sir, I got Serial, Board Serial, UUID and Appel ROM all from SMGenBios (for ROM I take the first three groups and replace the others with the last three groups from my own ethernet mac as described in dortania guide). I can start session with iCloud (new account). * Functional NVRAM -...

One week later I used a serial showed as 'unable to check coverage', I'm getting the same message :(

Yes, It's off and I have resetting NVRAM, but same occurs EDIT: after trying many times and started session in my microsoft account, it's shows like a nuc again.

Thing is I obtained the message from other computer after I started Windows from the NUC using Windows Boot Manager (with the Big Sur external disk disconnected). In any case, I am not concerned with the message itself, but with other possible effects in terms of security that it may have. I...

Hi again, I have seen some weird accesing https://account.microsoft.com/devices/ I got the 'system type' of my NUC shows as 'Macmini8,1'. I installed and run Big Sur in a external nvme deactivating the internal SSD (SATA port) in BIOS, and tried restoring a image of the disk but it always...

Thanks both, I will use one them, and I apologize for being so irritating... but out of curiosity, what's difference 'in practice' with: - The one I posted in english too: 'unable to check coverage' - The one you put 'serial number isn't valid' None of them are translatations, I have...

Sorry, just to clarify, there are two possible returned messages in english but both are really the same? - The one you put 'serial number isn't valid' - The one I posted in english too: 'unable to check coverage'

Thanks, but I tried using a proxy or through https://checkcoverage.apple.com/us/en/ and got the same text I put translated to english :(

Yes sir, sorry, because that I put the translation before, the message says: "Sorry, we are unable to check coverage for this serial number. Please check the information and try again".

Hi all ! I insllated Big Sur in NUCintosh about 10 days ago but I haven't used it because trying to get an 'invalid serial'. Thing is I tried about 100 serials generated with GenSMBios with no luck: i got 95% 'Sorry, we are unable to check coverage for this serial number. Please check the...

Finally I got today a nvme EMTEC X300 256GB today and a USB-C case, and installed Big Sur with no problem. it took half time this way, 2:15 hours in my NUC8i3BEH.

I have installed Big Sur in a Crucial MX500 SSD using a external usb 3 case (it took about 4 hours in a NUC8i3BEH!) and confirm that everything but the wifi works well. I used the 'NUC8i7OC7.3.zip' file (I didn't tried with the newer 7.4 or 7.5 OC versions). 1) Internal Bluetooth works (I have...

Ok thanks again, I asked because I have not the drive yet, but I will buy it and try :thumbup:
