MAMP with BrowserSync and Wordpress

Running local on MAMP got BrowserSync running because I get the dashboard overview with local:3001, however I'm having a tough time trying to get it to sync after any CSS changes.

Here's what I've got in the command line:

    > sudo browser-sync start --proxy genesistesting:8888 --files “wp-content/themes/genesistesting/**/*"
      [BS] Proxying: http://genesistesting:8888
