Unable to Reinstall Mac OS when reset to factory settings
1. I am getting the operation cannot be completed Chunkeddownload error 5 while installing Mojave
2. I am getting unable to download installer information failed on target volume while installing Catalina
3. I tried installing with bootable USB Mojave but I get error saying you this Mac is not allowed to use external drive and can't even change the security settings as it asks for password and when I click on it it says No Administrator found. I am just stuck here. Really need help to Reinstall macOS again, right now my Mac is dead.
