@Sebastian-Roth honestly, I missed that part initially but found it right after my latest post. I actually just successfully got the partition to expand using some combination of gparted and disk utility. Now I’m trying to nail down exactly what made it work so I can streamline the process.
Do you have any insight on which imaging technique I should use? Is the RAW method still required now that I’ve converted away from Core Storage?
Thanks for the help and replies Mr Roth!
