Mac Power Users is produced by Relay and built around a rotating set of co-hosts — David Sparks, Stephen Robles, and Stephen Hackett — who move between structured single-topic episodes and looser panel-style discussions. Many episodes function as long-form tutorials: one walks through Keyboard Maestro macros and its companion Field Guide, another covers iPadOS 26's new windowed mode and Stage Manager behavior, and another catalogs small AI-driven automations built with Claude and Apple Shortcuts. Other episodes bring in outside guests: Brett Terpstra and Christopher Gambre-Wellencheck of the automation consultancy Bear and Glass discuss keyboard remapping tools like Karabiner Elements and Hyper Key setups, while journalist David Pogue recounts Apple's 50-year corporate history, including the canceled Project Titan car project and internal Face ID testing. Recurring subject matter includes Mac and iPad productivity software, file-automation utilities (Hazel, CloudMounter, Raycast), hardware controllers such as the Elgato Stream Deck, iCloud data security, and smart-home troubleshooting with Home Assistant and HomeKit. Several episodes fold in listener-email segments where audience workflow tips and corrections get read and discussed on air. The tone is practical and instructional rather than newsy, aimed at people who already own Apple hardware and want to configure it more efficiently. Sponsor reads and pitches for the ad-free More Power Users membership typically appear in the show's opening minutes. Guests tend to be either app developers explaining their own tools or writers covering Apple's broader history rather than industry pundits. The format is conversational, often opening with a personal setup change or listener problem before settling into the episode's main topic. Listeners looking for workflow templates, automation walkthroughs, and detailed commentary on new Apple software features are the core audience.
