MacBook Internal SSD Not showing up in System Information or Disk Utility
Yesterday I had the same problem and solved it by creating a bootable USB with Mac OS Mojave.
Next you need to power on the Mac while holding Option, then select &quot;boot from USB&quot;. Wait and open Disk Utility and the SSD will be there.
This solution worked for me. I think disk utility in network recovery is limited or is a old version without support.
