WRITING
Notes from inside the hinge.
Still reads the lid angle sensor in a MacBook hinge thirty times a second. Building that meant learning a lot about how macOS handles lids, sleep, screensavers and screen capture — most of it badly documented. These are the guides I wanted while writing it.
How to get free Duo animation for Mac
Build Still's open source MacBook lid animation: compatibility, the free source download, installation and troubleshooting.
The MacBook lid angle sensor, explained
Which Macs have one, what it actually reports, and how to read it yourself over IOKit HID. Includes working Swift.
MacBook clamshell mode: the complete guide
Running a MacBook with the lid shut and an external display — what Apple requires, what it does to thermals, and the myths worth ignoring.
How to stop a MacBook from sleeping
Six ways, from a one-line terminal command to a lid-closed setup that survives a reboot. No third-party app required.
The best free Mac screensavers
Aerial, Fliqlo, Brooklyn and the built-in ones worth using — tested on macOS 26, with the security settings people forget.
Minimal clock screensavers for Mac
Fliqlo made the flip clock famous. Here is what still works on Apple Silicon, and what to use now that Flash is gone.
Taking one screenshot with ScreenCaptureKit
Why a single still image needs the Screen Recording permission, and how to capture every display in one pass. With Swift.
THE APP
Still folds your desktop
as the lid comes down.
Free, MIT licensed, and it never sends anything anywhere. Works on any MacBook with a lid angle sensor.
