Vemedio has released version 1.2 of Instacast for Mac with a new architecture for synchronizing podcasts between your Mac and iOS devices. By sending smaller bits of data, this new scheme ensures that all your devices are synced with the same state while also saving on network traffic, storage requirements, mobile data charges, and battery power. You’ll need to update to version 4.5 of Instacast for iOS to continue syncing your podcast subscriptions to your iPhone, iPad, or iPod touch. ($19.99 new from Vemedio and the Mac App Store, free update, 7.0 MB, release notes, 10.8+)
Thoughtful, detailed coverage of the Mac, iPhone, and iPad, plus the TidBITS Content Network for Apple consultants.
