- Electron version: 0.37.7
- Operating system: MacOS 10.11.4

Create a directory with the attached `package.json` and `main.js` files. The app just calls `app.makeSingleInstance` (code sample copied from the Electron docs) and then creates an empty window.

[package.json.txt](https://github.com/electron/electron/files/233556/package.json.txt)
[main.js.txt](https://github.com/electron/electron/files/233558/main.js.txt)

Type:

```
    rm -rf ~/Library/Application\ Support/Electron
    npm start
```

The app will display

```
    ### version 0.37.7
    ### shouldQuit:  true
```

...even though no other instance is running.

If you create an empty ~/Library/Application\ Support/Electron directory, the app runs as expected.

(Obviously, any established Electron developer will have such a directory and will not notice this bug. Their users will notice it very quickly indeed.)
