I just updated to Mojave. I used to use emacs-mac from https://bitbucket.org/mituharu/emacs-mac/ but with Mojave I just get blank window for emacs. I also tried emacs-plus and building on my own both which had the same issue.
The installation from https://www.gnu.org/software/emacs/ and emacs in the terminal seems to work fine. But I need dvisvgm support which neither has.
Please let me know if you would need more information.
