My external SSDs are APFS and I've had no problems at all. One is a clean install of the current OS version and the other holds some large files I do no need to have on the boot partition, but still want to have on a fast drive (Game installs, mostly). Stay away from APDFS on rotational drives for now, and quite possibly forever as all the real benefits of APFS require fast drives. That said, snapshots and "virtual”partitions are brilliant. > That having been said, I have no idea why your external won't boot.

If a drive shows up as bootable in the Startup Disk CP, it's generally bootable. I'd probably try an over-the-top install of the current OS. Also, look at it in `diskutil list disk1`(command line) and see what its partitions look like. (Disk1 being the line in question, could be disk4, etc). This is what mine looks like: $ diskutil list disk1 /dev/disk1 (internal, physical): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *3.0 TB disk1 1: EFI EFI 209.7 MB disk1s1 2: Apple_CoreStorage DATA 3.0 TB disk1s2 3: Apple_Boot Recovery HD 650.0 MB disk1s3 -- My main job is trying to come up with new and innovative and effective ways to reject even more mail. I'm up to about 97% now.
