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+)
Mac OS X Services in Snow Leopard
Mac OS X Services let one application supply its powers to another; for example, a Grab service helps TextEdit paste a screenshot into a document. Most users either don't know that Services exist, because they're in an obscure hierarchical menu (ApplicationName > Services), or they mostly don't use them because there are so many of them.
Snow Leopard makes it easier for the uninitiated to utilize this feature; only services appropriate to the current context appear. And in addition to the hierarchical menu, services are discoverable as custom contextual menu items - Control-click in a TextEdit document to access the Grab service, for instance.
In addition, the revamped Keyboard preference pane lets you manage services for the first time ever. You can enable and disable them, and even change their keyboard shortcuts.
