Build sbndcode for OSX 10.12 (Sierra) instead of 10.10 (Yosemite)
Support for OSX 10.10 ("Yosemite") is going to be dropped by Fermilab on November 10, 2017.
We will not be able to build binary distributions for that operating system any more, which apparently does not matter since nobody is using it.
I recommend, given the user distribution from the poll, to prepare OSX 10.12 ("Sierra").
Building SLF7 would also be good, given that same poll.
