I'm trying to run SlimerJS in headless mode so that it does not open a visible browser window on Mac OSX.
According to the SlimerJS docs, this can be done using xvfb which is "available on Linux and MacOS", using the command:
>> xvfb-run ./slimerjs myscript.js.
Although OSX comes with bundled with xvfb, it does not have the corresponding xvfb-run script.
How can I get the same functionality using the OSX xvfb version?
