Mac­ness have released their final ver­sion of gSync. An app that allows bi-dir­ec­tion­al syncing of iCal and Google Cal­en­dar. I have been using it for most of it’s life through beta and can say it works per­fectly. As an added bonus, in com­par­is­on to the sim­il­ar Span­ning Sync, it is priced much more reas­on­ably at $20.
