iOS 27 adds Lock Screen Focus toggle tailored to iPhone Duo

Developer pdfu, working from an iPhone Duo simulator, found a new control on the device's Lock Screen that lets users quickly disable and re-enable an active Focus mode without unlocking the phone. The toggle sits above the camera and flashlight icons, and the active Focus mode's name also now appears in the status bar near the clock. This follows other Duo-specific tweaks pdfu has uncovered, such as a relocated dock and new StandBy views.

macOS screen-sharing flaw CVE-2026-65400 exploited to plant crypto miners, Apple patches it

Dutch cybersecurity officials warned that attackers are actively exploiting a high-severity macOS vulnerability in the screen sharing feature, gaining root access on exposed systems and installing Monero crypto miners. Apple issued a patch last week for Tahoe, Sequoia, and Sonoma after the flaw, rated 7.1 of 10, was disclosed at the Black Hat security conference; the company credited security firm Bynario with the finding.

Open-source tool RemoveMacAI lets Mac users strip out Apple Intelligence files

A developer released an open-source command line tool called RemoveMacAI that disables Apple Intelligence features and deletes the underlying AI models from macOS, freeing up storage. The tool addresses the fact that macOS 27 removed the single toggle to turn off Apple Intelligence, scattering controls across multiple settings panes including Screen Time. It also includes a revert command to restore the features and re-enable model downloads.

Android Authority found a new lock screen customization page hidden in the Wallpaper & Style app on the first Android 17 QPR3 beta.

Currently, Pixel owners customize lock screens through a swipe-based menu with separate settings for clock, shortcuts, and notifications.

Report warns MacBook screen protectors can damage anti-reflective coating

A tech advisory highlights risks of using adhesive screen protectors on MacBooks, noting they can degrade display clarity and, more seriously, damage the anti-reflective coating when peeled off. Thicker protectors may also prevent the laptop from closing properly, risking further screen damage from the hinge mechanism. The report points to magnetic alternatives, such as Kensington's UltraThin Magnetic Privacy Screen Filter sold on Apple's site, as safer options.

Explainer: How V-Sync caps frame rate to match monitor refresh rate

V-Sync is a graphics setting that forces a GPU to hold back frames until a monitor's refresh cycle is ready, rather than sending frames as fast as it can render them. This prevents screen tearing, a visual glitch where a frame appears split horizontally because the display updates mid-render. With V-Sync on, frame output is generally capped to match the monitor's refresh rate, such as 60 FPS on a 60Hz screen or 144 FPS on a 144Hz screen.

Explainer: Why screen tearing happens and how to stop it

Screen tearing occurs when a GPU sends a new frame to the frame buffer before the monitor finishes scanning the previous one, causing two frames to appear on screen simultaneously. This happens because GPUs render frames at variable rates while most monitors refresh on a fixed schedule measured in hertz, such as 60Hz, 144Hz or higher.

NYC junkyard playground lets kids use real saws and hammers, unsupervised

A New York City playground called 'The Yard' gives children access to real tools — saws, hammers, nails, wheelbarrows — in an unstructured, screen-free environment, according to the Wall Street Journal. Adult 'playworkers' supervise from a distance but largely let kids direct their own activities, and parents sign liability waivers before enrolling their children, with the site carrying its own insurance.

New macOS app SCM offers local AI search across photos and video frames

A Show HN post introduces Screen Memories (SCM), a macOS application that lets users search photos and every frame of video using natural-language queries, OCR, and spoken-dialogue search via Whisper. All processing runs locally on-device through a local vision model, with no cloud uploads or accounts required, and the app auto-imports watched folders and re-embeds content when models change.

Samsung Galaxy Tab S12 Ultra and iPad Pro face-off in premium tablet market

Samsung's Galaxy Tab S12 Ultra, priced at $1,399.99, features a 14.6-inch display and aims to excel in screen size and battery life. Apple’s iPad Pro, with a starting price of $1,499 for the 13-inch model, emphasizes processing power and display precision. Both devices target professional and creative users but differ significantly in design philosophy and ecosystem integration.

9to5Mac writer tests iPad mini as stand-in for unreleased iPhone Duo

A 9to5Mac writer has been using an iPad mini, loaded with the same apps and layout as their iPhone, to simulate the experience of Apple's rumored foldable iPhone Duo. The experiment relies on an iPhone Wi-Fi hotspot for connectivity and notes that the Duo's rumored 7.6-inch interior display is only slightly smaller than the iPad mini's 8.3-inch screen. Colleague Ryan Christoffel's reporting on the Duo's screen size was cited as the basis for the comparison.

Apple confirms iPhone Duo's matte screen layer is replaceable

Apple vice-president Kate Bergeron told a TikTok creator that the iPhone Duo's matte display coating, which helps minimize the crease on its foldable screen, can be replaced over time. She did not specify pricing or whether users can do this themselves, but described significant engineering work to extend the layer's performance.
