I'll also add that if you wanted to, you could build any version of AFNI using the github pull and an updated Makefile that I wrote specifically for 10.14 (probably 10.13 too) that uses homebrew for dependencies and Anaconda for Python. It's part of the distribution and a solid starting point. Let me know if you have questions should you decide to build other iterations.
