Unable to recover Mac OS on latest Macbook Air.
Hello everyone. My friend asked me to install Windows on his new Mac
Air. He was OK with swiping the mac os and reinstalling everything from
scratch. His Air was already linked to his apple id and had "activation
lock". To remove it, i asked him to remove this laptop from devices list
in "Find my iphone" area of his icloud account. I erased the disk
hoping to go through internet recovery as i've done many tiems before,
but here i was stuck in a loop: mac starts the internet recovery
(spinning globe) for about 10 min, then it boots into the recovery
assistant mode and suggests to enter the new apple id. After i do that,
the only option i have is to "reboot", and after reboot everything
starts over. This "recovery assistant" mode is very limited, too,
lacking usual disk utility, startup security utility etc etc. The only
options it has are to erase the disk or choose boot volume. So i decided
to avoid internet recovery altogether and made a bootable usb drive
with Mac OS Catalina. Now i get a different error - security settings
do not allow this Mac to use an external startup disk. And to fix it i
am suggested to - guess what - change settings in the startup security
utility which i have no way of accessing. So basically i have i laptop
without any kind of OS now and i'm completely lost.
