In tech, ‘dogfooding’ means using your own stuff in the way you intend for your users to, which is helpful to make sure your stuff lives up to your marketing claims. Apple dogfoods in a number of ways, but one particularly visible way it’s doing that is with the event video from today’s ‘Scary Fast’ pre-Halloween keynote, which introduced new M3 Macs, including the latest MacBook Pros and iMac. The entire pre-recorded event video was shot on iPhone 15 Pro Max – including the aerial drone shots – which is a flex for a company that can literally afford the best production equipment and gear available to anyone, anywhere.
