other than that, im out of ideas.Ĭan someone explain how i lost my serial number, and explain the weird quirks (missing drm, unauthorized deregistering my mac from icloud) that are happening as a consequnce?

The other possibility, is that apples hardware and logic boards are flawed, and they can erase their oen serial numbers.

Assuming that apples technology is impenetrable, then you would have to assume that someone stole apples special software and one of their keys, and used it on my logic board remotely to deserialize my mlb.

Supposedly, once a certified apple technician burns a serial number into your logic board, it is impossible to remove unless you have specialized software that contacts apples servers with a registered signature and encryption key, and waits for apples servers to send authorization to write or remove the serial number from the logic board. After removing time machine drive, i opened the apps, and low and behold, all of them worked perfectly without asking me to sign into icloud, or log into the app store. Then, instead of importing my files with migration utility, i simply dragged and dropped my digitally purchased app store apps from my time-machine backup, onto my clean install. I concluded this, because after the clean install from internet recovery, I DID NOT SIGN INTO ICLOUD. One more strange quirk is that apparantly, this somehow also deactivated all of apples DRM (digital rights management) for any of the apps that i had purchased. I never signed myself out before erasing.

I had a botched filesystem runnig mac os Catalina 10.5.7, and so i decided to do a clean install, and then do an internet recovery.Mac OS No longer has a serial number and shows "Serial Number (system): Not Available" in system profiler.
