I think I once had hashcat with High Sierra on this MAcBook Pro with OpenCL running. Apple does not support OpenCL anymore, so maybe you try an older version of hashcat, I do not remember which one it was but for sure not 6.
Where might one find older versions of hashcat? High Sierra was 2017 to 2018, so a version from 2018 should do the trick if you are remembering correctly. As long as the 2018 version supports -m16700 aka filevault.
EDIT: found old versions, running 5.1 now and it does appear to be running on my GPU. I'll know more in a minute. The benchmark was about 26x faster than the CPU benchmark
Makes me wish I put two RX480's in this Mac Pro, which was my original plan 
EDIT EDIT: From 70 day ETA via CPU, to 3 day ETA via GPU. The fan volume is going to be annoying but it's also going to be very short lived so I can deal with it.
