I am trying to create a bootable installer for macOS Big Sur to use on a 2016 MacBook Air that cannot reinstall macOS in recovery mode. I am using an M1 MacBook air to create the bootable installer. I am using a 32GB flash drive and I have downloaded the macOS Big Sur installer, but when I try to use terminal to complete the process, I get an error that I haven't found a working solution to online. I have tried multiple times but keep getting the same error:
I have tried using the flash drive as both ExFAT and Mac OS Extended (Journaled), both times in GUID Partition Map Scheme. The MacBook I am creating the installer on came with Big Sur preinstalled, so it should be able to create an installer for it. Also, the reason the 2016 MacBook air can't reinstall macOS is because I get the error "The installer information on the recovery server is damaged." If there is a way to circumvent this without using the bootable installer, that works as well. Just anything to get macOS working on the MacBook would help!
