I had my NUC stop working, but reinstalled Cat and maybe EFI. The Hacs don't seem to like having more than one drive running Clover on the NUCs (I had three installed). The Clover installs seem to write on each other's EFIs (and Win10's efi which I removed). This is probably half of my troubles with the Hacs. I got it working again and am trying to put the serials into it with SMBIOS and got a serial that is Invalid and one that is not activated/Validated. The problem is that the instructions say that you want number three (Validated) but in Note 2 it says that in the long term it may be better to use the invalid serial since someone may purchase and want to activate their serial. (Big Conflict) That makes sense, but I thought that the procedure was to get a Valid serial and activate it - but note two advises against it more or less. I find this a little contradicting/difficult. I could care less about iMessage etc. I am still running Yosemite on my UD5H which has been much less trouble. No iMessage and I guess you don't need the serials (on Yosemite). It works reliably, but is aged. The Question is: do I just use the Invalid serial to avoid hassle later which makes some sense, or use an invalid and not expect to call the support line with issues? I have my new (2018) mac mini which I can use if a problem arises. It appears that the issue is iMessage requires a Unique Serial to know where to send the messages, so you want a serial. Don't use the Valid one because of Later conflict, and the only real problem is Don't Bother the support line with your issues since they may object. Is this the bottom line? I am putting my serial operation on hold while I wait for your input.
I really appreciate and value your input and advice. Thanks,
