This app turns the iPhone Duo into a pocket-sized Mac

Headroom uses macOS's built-in Screen Sharing to let users control their Mac from the foldable iPhone, without installing additional software on the computer.

Headroom App on Apple iPhone Duo controlling a Mac — Headroom

The iPhone Duo has barely been out for a day, and someone’s already found a way to run their Mac on it. Well, sort of. Headroom, a remote desktop app from MusicFlow, lets users control their Mac from Apple’s new foldable phone, with an interface that adapts as the device opens, closes, and folds in half. Think of it as turning a pocket-sized phone into a miniature MacBook, minus the actual MacBook.

Headroom turns the iPhone Duo into a mini Mac

Headroom connects directly to macOS’s built-in Screen Sharing feature, so there’s no extra software to install on the Mac and no Headroom account or intermediary server required. Once Screen Sharing is enabled, users can access their Mac remotely. The app was originally built to let its developer keep an eye on an AI agent working on a Mac from the sofa, which feels like a very 2026 problem to have.

The clever part is how Headroom handles the iPhone Duo’s folding design. Half-open like a laptop, the Mac appears on the upper screen while a software keyboard occupies the lower one. Fold it fully open, and the Mac fills the inner display. Close the phone, and the outer screen works independently. The interface also keeps controls away from the hinge, so nothing important gets awkwardly sliced across the fold. Hardware keyboard users get a bonus, too: the lower screen can become a panel of large keys.

It works beyond the iPhone Duo, too

Headroom isn’t just a folding-phone party trick. It also runs on iPad and Mac, supports 17 languages, and uses Apple’s Metal graphics technology alongside ZRLE compression to keep remote screen rendering smooth. Users can interact through touch or a mouse, with support for gestures such as scrolling, dragging, and zooming. For access outside the home network, the developer recommends using a VPN such as Tailscale.

The app is free to try, while a one-time Pro purchase removes the connection time limit. For anyone who needs to check on a desktop Mac, manage a headless Mac mini, or simply poke an AI agent from the couch, Headroom offers a neat way to do it. The iPhone Duo may not replace a MacBook just yet, but it can apparently borrow its desk job.

PHP is the programming language behind roughly 70% of websites, and it just ran into a serious problem. Security researchers used AI to uncover a critical flaw called PHP2Shell, which could let attackers take over web servers, steal data, or disrupt online services. Since the discovery, websites worldwide have been hit with millions of attempts to exploit it.

Hackers moved fast once the flaw went public. Cloudflare CEO Matthew Prince said the attack attempts jumped from tens of thousands within 45 minutes to millions overnight, The Guardian reports.

Microsoft has begun rolling out Copilot Code for building apps with natural language

The workplace-focused vibe coding tool can pull context from emails, documents, meetings, and chats.

Microsoft introduced Code last month as one of the three core parts of its revamped Copilot app. The app was pitched as an easy-to-use coding agent that lets users describe what they want to build in natural language, like an app, a tracker, a dashboard, an automation, or a workflow, and Copilot would build it for them.

Essentially, it's a workplace-focused vibe-coding app that turns existing work into a functional app, and Microsoft has begun rolling it out through the Frontier program.

AI agents are acting like rogues and causing a huge headache for US banks

US banks block AI agents over fears they could make unauthorised financial moves

Banking

US banks are facing a new kind of digital headache: artificial intelligence agents attempting to access customer accounts and perform actions that may go beyond what users intended. As AI tools become more capable of navigating websites and carrying out tasks independently, financial institutions are scrambling to prevent them from crossing security boundaries.

According to a report published by Axios on October 22, major US banks have detected third-party AI agents operating inside customer accounts without authorisation. Some agents reportedly appeared to attempt actions independently of user instructions. The banks involved have not publicly detailed every incident, and there is no evidence that the reported activity resulted in widespread theft of customer funds.
