It does work well, except when there's a macOS major version bump (10.9 -> 10.10 -> 10.11 etc.).
Then you update your system (maybe after a prudent 3 week wait) and everything works, except the GPG Suite, and you can't send encrypted emails for a while, nor can you read ones you receive, or old ones stored locally.
(For macOS 10.12 sierra, released 2016-09-20, there's now a beta of the GPG Suite, released 2017-01-23, 4 months later.)
There was also a bug (or feature?) a while ago where email drafts that you had open in windows would vanish after a while.
It is a good solution for the Mac, but this is something to be mindful of (and it sort of supports the main thrust of the article).
