thanks Pilgrim, very clear guide. Followed with ease, tho have not reconnected internet and tested yet - thought I'd sleep on it, double check everything tmrw. Meanwhile, two questions, general, not help per se:
In several comments in this thread, I see references to SimpleMBL, but don't see this anywhere in the guide. Is this something that has been updated out, and does MBL created by "Generate New" in Clover Configurator now obviate what SimpleMLB previously did? or have I missed something?
Also, I run two Hackintoshes as music work stations, and don't use that many Apple services on these, including not using iMessage. But I also have legit MacBookAir, iPad Pro and iPhone, and I run all these and my Hacks on the same AppleID, mainly for iCloud syncing of Safari bookmarks/passwords, Notes, Reminders, etc.
Two-three times all my devices have suddenly gone nuts, rejecting AppleID logins (Apple ID or Password not correct"). Even using 2FA each time it was a major PIA to get all devices sorted with new password and all working. One such incident the other day prompted me to look at Clover SMBIOS and related stuff in one of my Hacks, and I found it all looked pretty messed up, which led me to your guide.
This got me wondering, do you suppose something like App Store OS updates or other non-iMessage Apple Service activity from a hack with messed up Serial Number, smUUID, etc, might have triggered AppleID/password rejections?
Thanks again
