I'm trying to reinstall MacOS Catalina on a second hand Macbook Pro 2019. I cannot access Disk Utils in any way specified on the web. Only option that is available is Internet Recovery and I face an "Activation Lock" window that I cannot seem to bypass whatsoever.
In Internet Recovery window I have the following options: shutdown, restart, activate using MDM key and Erase Mac. The last option is: Startup disk that won't allow me to boot on my USB. It gives the following error:
security settings does not allow this mac to use an external startup disk<
How can I format and reinstall this Mac? I do not know the Apple-ID used for this Mac and neither does the previous owner.
