John and Dave have a great show this week, answering questions about setting Mail’s default sending account, enabling Photo Stream without a computer in the mix, understanding why OS X manages your Address Book the way it does, diagnosing both sleep issues AND runaway process issues, and much, much more. Plus, there’s another timely summer, lightning-related discussion thrown in, as well. Don’t miss this one, folks! Download and enjoy today.
