OSX: What to do when Meteor build never stops?

When your app starts to get big, you may end up using more than 256 files. On OSX, the build process may never finish the build owing to this nasty bug: https://github.com/meteor/meteor/issues/6952.

If you hit this limit, simply increase your kernel capabilities by creating a file named /Library/LaunchDaemons/limit.maxfiles.plist with the following content and reboot:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN"
        "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
  <dict>
    <key>Label</key>
    <string>limit.maxfiles</string>
    <key>ProgramArguments</key>
    <array>
      <string>launchctl</string>
      <string>limit</string>
      <string>maxfiles</string>
      <string>524288</string>
      <string>524288</string>
    </array>
    <key>RunAtLoad</key>
    <true/>
    <key>ServiceIPC</key>
    <false/>
  </dict>
</plist>

You can check your new settings on the CLI:

$ ulimit -n
524288
