I apologize if this has been answered elsewhere, but my keyword searches of the forums haven't turned up the answer.
I finally decided to upgrade MacOS by doing a clean install, but being overly cautious, I decided to install on an external HDD first, setup, and test it before cloning it back to my boot drive. When I got everything configured, I used Carbon Copy Cloner to copy the fresh install of Catalina (yes, I know... it's not all that new, but I'd like to stick to OSX 10 a little while longer) back to my NVMe boot drive. It worked as expected, and I was able to boot into Catalina.
However, my old Mojave volume appears alongside the new Catalina volume in OC's boot picker (using OC 0.9.3). I didn't rename the drive, so it is showing 2 "bootable" volumes with the same name, but if I pick the old Mojave volume, it gives an error (something about the pre-linked kernel... can't remember exactly). If I hit <space> to show all volumes, I also see the old Mojave recovery partition as well.
This "ghost volumes" do not appear in terminal, diskutil, or Disk Utility. Disk First Aid showed no errors on the protected or data partitions of the boot drive. Clearing the NVRAM or rebuilding the kernel cache did not fix the problem.
So far, it appears to be mostly cosmetic, but I'd like a way to fix it.
Any help would be appreciated.
