- Electron version: 1.2.6
- Operating system: osx yosemite

Do the autoUpdater objects on osx and windows have different properties? On windows, when i do `console.log(JSON.stringify(autoUpdater));`
I see the properties `domain`, `_events`, `_eventsCount`, and `updateURL`. However, doing the same thing on osx only allows me to see the properties `_events` and `_eventsCount`. 

I want to access `updateURL` in my code but I'm wondering whether that property is accessible. Maybe I should submit a PR for a `getFeedURL` method?
