My Mac doesn't activate the Disk Utility
Hi.
I have Windows installed using Boot Camp and I believe it is related with the issue.
My Mac is a MacBook Pro 2018, model A1990 with chip T2 Security.
My problem is the following:
I went to Disk Utility and erased my hard drive, formatting it as APFS Encrypted.
Then I tried to install the macOS again, but it was not allowed, because the Disk Utility showed a message saying I couldn't install the app in the MacOS partition because it has a password. But it didn't ask me to type the password, it just blocked the SDD drive.
Then I turned off the Mac by the power button. And the nightmare started.
I already reseted the the SMC, NVRAM, used Command + R, Command + S, Shift + Control + Option, turn on the Mac holding Shift, and everything that is available on the forums.
The situation is the Mac doesn't show The Disk Utility or the Startup Manager anymore. The Mac cannot find the MacOS partition.
But I have no issues for starting the computer using the Windows partition (Boot Camp).
The Mac ask by default to make an Internet Recovery, but I tried it many times and it doesn't work, showing always the same message when it finishes: support.apple.com/mac/startup-2100F. This number after the dash (2100F) always change.
I tried a flash drive with a bootable installer, the Mac recognize the drive, but when I chose to install from the flash drive, it drives the Mac to use the Internet Recovery mode automatically, totally ignoring the flash drive. I am about 7 hours trying to fix it, but zero progress.
I attached here what happens step by step. I hope someone can help me.
STEP 1: adm password is required when I turn on the computer
STEP 2: bootable installer
STEP 3: redirect to Internet recovery
STEP 4: Error
