BUSCO on MacOS/BSD
We know that the part of Augustus dealing with block profile in BUSCO has issues on Mac and FreeBSD. It affects, for example, versions obtained with conda and homebrew.
In this case, unless you manage to fix Augustus you cannot use BUSCO on a Mac. From v4, we recommend the Docker container instead that will work perfectly on a Mac. https://busco.ezlab.org/busco_userguide.html#docker-image
