Make pdf fails, undefined control sequence error

[gcagle1]

Hello!

Thank you for the package, I'm really excited to start using it. I downloaded MacTex from homebrew casks with brew cask install mactex and followed the sudo commands in step 4 after getting the error described in the install instructions. My problem is that make pdf produces the message No pages of output. and a few other warnings and notifications but I can't find a specific error message.

Make html and make docx successfully produce output (yay!) The messages I get for make pdf are really long and I don't want to overwhelm this comment, so here is a subset I think might be useful.

! Undefined control sequence.
<argument> \c_sys_engine_xetex_bool

or this?

*** you should *not* be loading the inputenc package
*** XeTeX expects the source to be in UTF8 encoding
*** some features of other encodings may conflict, resulting in poor output.

I also wonder if the issue could be due to installing MacTex via homebrew. This is the return from which tex: /Library/TeX/texbin/tex

I would greatly appreciate help figuring out what the issue is with producing the pdf. Thanks in advance!
