This all started because I was trying to clean install a Macbook Pro that someone sold me.
They gave me the password to log into the computer under their profile so I could clean install it.
I started the process of erasing Macintosh HD so I could reinstall macOS (Catalina).
While trying to erase, I was prompted for the previous user’s password for their Gmail so they could be logged out of Find My Mac. The profile password didn’t work for this.
I accidentally erased Macintosh HD – Data, and now the computer won’t let me log in at all.
Here’s what happens: I turn the Macbook on, it goes to the login screen like normal.
I enter the password that worked before, but now this happens.
And when I hit a key, I am sent back into the login screen.
And there’s no way out of this loop except to go into Recovery Mode.
When I go into Disk Utility, this is what Macintosh HD looks like.
When I try to mount the Macintosh HD, I get this error.
I tried resetting the NVRAM, I tried doing internet recovery on Macintosh HD – Data. Nothing changed.
Any help I could get would be greatly appreciated.
