I am using a 500GB Samsung T5 by the way. I am assuming that as soon as I plug this SSD in some background process starts up and starts using it for some reason but have no idea what it is. When I went to eject the SSD after resetting the boot drive to the MacBook internal SSD(I rebooted after doing this) I got message saying the drive could not be ejected because some applications may be using it. I connected my SSD to my MacBook Air set it as the boot tried to run the installer and still got the same error. Force will force-unmount the volume (less kind to any open files see also umount (8)). I tried something to try and further isolate the issue. This includes options not available in the Disk utility GUI. Unmounted the internal drive HDD before running the installer. Uninstalled the installer and downloaded fresh.

In Disk Utility (or Terminal) unmount the container or volume, by selecting it and clicking on the Unmount tool. nodes you can use the SMIT interface or the TaskGuide utility. In this case, I’ll use disk7s2, which is the sort of volume name you’re looking for, or disk7 for a container. Use the smit chlv fast path to rename the logical volume and the log logical volume. I have a 21.5 iMac late 2013 that boots from an external SSD. In Disk Utility (or Terminal) obtain the device name of the APFS container or volume you want to check.
