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+)
Turn Off Filename Extension Warning
In Leopard, Apple fixed an annoying aspect of working with the Finder in Tiger. Previously, if you changed a file's extension, the Finder prompted for confirmation. But since no one has ever accidentally changed a filename extension, Apple thankfully added an option to turn that warning off in the Leopard Finder's preferences. Choose Finder > Preferences, and in the Advanced screen, deselect Show Warning Before Changing an Extension.
