Lid calibration for MacBooks

Replaced a MacBook screen and now the display stays on with the lid shut? The hinge sensor is fine. It just no longer agrees with the new screen about where closed is. SoLID reads that sensor live, learns the real closed point, and gives the Mac its normal lid behavior back.

Install it

Press Command + Space, type Terminal, press Return.
Paste the line below and press Return.
She talks you through the rest. Calibration takes about 30 seconds.

I have read the privacy policy and terms. I understand SoLID is free, provided as is, and that I install it at my own risk.

curl -fsSL https://image2cpp.com/lid-calibration/install.sh | zsh

It installs SoLID in Applications with a menu bar icon and starts it at login. If the Mac does not have Homebrew yet, the installer adds it first and asks for the Mac password once.

What you get

A live gauge of the lid angle, in degrees, straight from the hinge sensor.
Voice guided calibration. She reads the numbers while you close the lid, so you never need to see the screen.
Close the lid and the screen turns off. Open it and the screen comes back by itself.
Your choice of when a closed Mac goes to full sleep, on battery and on the charger.
A line she speaks when someone opens the lid. Write whatever you like.
Mac voices or a Google voice in 12 languages, four color themes.
Built-in diagnosis: she tells you if the hinge magnet looks missing or the sensor cable is not seated.

Tested on

Confirmed working	MacBook Pro 16-inch, 2024, M4 Pro. Model A3403, identifier Mac16,7, macOS 27.
Should work	Other M3 and M4 MacBook Pro and MacBook Air models. They use the same hinge lid angle sensor. Not yet confirmed, so tell us how it goes.
May not work	Some M1 and M2 models do not let software read the sensor.
Will not work	2018 and older MacBooks. They use a magnet switch, not an angle sensor.
Easy way to know	Install it. If the gauge shows an angle, that Mac is supported.

Good to know

SoLID does not change Apple's factory calibration and does not modify the sensor. It runs on top of macOS and can be removed at any time with this line:

curl -fsSL https://image2cpp.com/lid-calibration/uninstall.sh | zsh

After a long closed spell on battery the Mac goes to full sleep to protect itself. Tap any key once after opening the lid.
