Someone has already found a way to run a Mac from Apple's new foldable iPhone Duo. The app is called Headroom, from a developer named MusicFlow. It lets you see and control your Mac from your phone, and the screen layout adapts as the phone opens, closes and folds in half.
What it does
Headroom connects to Screen Sharing, a feature already built into macOS. That means nothing extra to install on the Mac, no Headroom account and no middle server. Half-open like a laptop, the Mac shows on the top screen and a keyboard sits on the bottom. Fully open, the Mac fills the inner display. Controls stay away from the hinge. It also runs on iPad and Mac and supports 17 languages.
Cost and who it suits
The app is free to try. A one-time Pro purchase removes the connection time limit. The material does not give a price. It suits people who need to check a desk Mac or a headless Mac mini, which is a Mac with no screen attached. The developer first built it to watch an AI agent working on a Mac from the sofa.
What to know before using it
For access away from your home network, the developer recommends a VPN such as Tailscale. A VPN is a private, protected connection between your devices. The material does not say how the app handles security beyond that advice, or when Pro pricing will be announced.
