 <p><strong>Edit:</strong> This isn't working now after rebooting again. I hate this! :/</p> <p>I also ran into this issue with Sublime Text 2 as well as Guard (it started using a polling fallback).</p> <p>I believe I found a fix:</p> <ol> <li>Download <a href="http://www.macupdate.com/app/mac/11582/onyx" rel="nofollow">Onyx</a> and run it with all of the options under the automation tab checked</li> <li>After it's done shut down your machine and turn it back on</li> </ol> <p>At this point I was suddenly able to see new directories created using mkdir in terminal from within the Sublime Text 2 file browser. Guard was also working without the polling fallback.</p> <p>I hope this helps, it was really starting to get on my nerves.</p>
