iCloud Validation failing

[haralds]

I revived my late 2012 Mac Mini and installed Mojave, Catalina, and Sonoma (using OCLP.)

I cannot fully log into iCloud on Mojave and Catalina. I go through the series of prompts:

These work:
- Enter iCloud account and password
- Send FSA to Messages and enter
- Reenter iCloud account password
- Enter Mac Mini account password
This fails:
It then asks to enter the password of one of my other Macs that is running Golden Gate. I suspect the encryption scheme is not recognized.

Sonoma under OCLP asks for an iPAd code, which works.

Has anybody found a workaround?

Cheers,
-- Harald

iCloud on our family iMac isn't working,
but works fine on my iPod touch & iPad
...trying to turn on iMac Settings to turn on Cloud web access & just get "Something wrong" msg.
worked fine before.

It is now so secure, you cannot use it!

Similar situation on two MacBook Pro, one 2012 and one 2019. Mojave installed and since a while, AppStore asking to enter password but gives a « failed request ». Fortunately, I was already logged in to iCloud so my account looks to be working. I didn’t tried iTunes or other services tied to AppleID though!

I updated one of the two laptops with Catalina on a SSD testdrive but same result. I suspect something related to Apple Intermediate certificate PKI but I am not sure!
