Is it possible to sync Microsoft Word 2011 for Mac with Google Docs?
If so, how?
Doesn't look like it there is a way to do so just between Google Docs and Word 2010 for Mac via the official Google Cloud Connect for Microsoft. There may be a 3rd party app that can do the job though. However, that is also unlikely since there isn't any API that is for Mac's version.
