You can also build the Graphviz GUI app using homebrew if you have Xcode installed:
brew install graphviz --with-app
If you already installed the graphviz brew, you will want to do this:
brew reinstall graphviz --with-app
At the time of writing, this doesn't appear to install a symlink to the app into /Applications like cask does, so if you want that you'll need to do it manually (or copy the application out).
To find the location of the app bundle, have a look at the build log, you should see a line like this:
If you don't have the build log anymore, you can determine this path by running brew list graphviz or brew info graphviz.
Open up the folder (replace this with the actual path you determined in the previous step):
open /usr/local/Cellar/graphviz/2.40.1
Inside here you should see Graphviz.app. You can move/copy it to /Applications or create an alias by dragging it to /Applications and holding the ⌘ and option keys.
As of 2018-12-21, for macOS mojave, there's an issue with using the
--with-app flag in the brew install command. See gitlab.com/graphviz/graphviz/issues/1445. Will update this when the
fix is working.
It appears as if there is an issue with Graphviz itself currently preventing builds on macOS Mojave. Please do not comment on this answer saying that it doesn't work, it will accomplish nothing. You may follow the issue above for more updates and we'll try to update this answer if/when the situation is resolved by the Graphviz devs.
If people want to help get this fixed, there is a partially implemented upgrade PR that needs some love to take it over the finish line (see comments.)~~
Update: build is fixed, but homebrew has removed GUI support
I'm afraid I don't have a new solution for how to do this other than manually building from source. If somebody has any ideas, please share them in the comments. I am going to keep this answer up as I think this should be the right way to do this, we just need more advocacy (and volunteer devs) to improve the user experience for Graphviz users on macOS.
New versions on macOS allow you to toggle the ability to view/work with hidden files.
For those developing on macOS - pressing down Command + Shift + Period (Command + Shift + .) in the file system of macOS will hide or show invisible files. This will allow you to toggle the ability to create and work with dot files.
For simple viewing or editing of dot files, this approach would probably work the best. Note that, while this toggle is active, seems to be a system wide switch, allowing other apps to access/open the dot files as you would any text file.
