How to thoroughly remove LMS 7.7.4 from Mac?

I have an issue that I think a reinstall should address, but it has so far survived my reinstall attempts.

I want to be certain I'm removing all remnants of LMS (especially related to plugins) from my Mac (Yosemite), do the instructions posted in the link below do so?
