why does the OS X app try to connect to google?
plus.google.com TCP-Port 443 (https)
What makes you think so?
There are no references to any sites (except the default hub) in the source code.
because little snitch tells my that the app wants to connect.
Seems to be nwjs, the component used by Byteball. Maybe it means NodeWebKit.js and is the browser-bundled up.
Google is known for adding a bunch of shit in every source-code they touch to "resolve" something on their servers. This could be information leakage, especially when using it over Tor - who knows what it sends to Google even if it is the hostname and datetime its too much.
@tonych, maybe see if there is a default option which has to be turned off when importing/using nwjs?
edit:
https://github.com/nwjs/nw.js/issues/5343 just one issue, expect 100 more "accidents" by google. edit2: if using the chromiu-args proxy workaround, make it something else than 127.0.0.1, like 127.6.6.6 to avoid more other problems.
