Editorial interest 78/100 Selection signal · not a rating of the site

SoLID reads a MacBook’s hinge angle sensor and recalibrates the point at which the computer recognizes that its lid is closed.

Landing page captured for the 2026-09-19 issue.

For: MacBook owners replacing screens
Worth noticing: Calibration is voice-guided and takes about 30 seconds, but compatibility varies by MacBook generation.

Field notes

SoLID is installed through a shell command and runs from a menu-bar icon, reading the hinge sensor rather than changing Apple’s factory calibration. The page describes a live degree gauge, spoken readings during lid closure, optional battery and charger sleep behavior, and diagnostics for a missing magnet or unseated sensor cable. Compatibility is clearest for the listed 2024 M4 Pro MacBook Pro; other models remain conditional.
