Hey I’m working on a macOS app that wants to detect the MacBook lid / hinge angle (i.e. how far the screen is open) by directly reading the internal sensor via HID / IOKit (a private / undocumented API). I came across this project: LidAngleSensor — GitHub: https://github.com/samhenrigold/LidAngleSensor?tab=readme-ov-file
Before investing too much effort, I’d like to ask the community:
Has anyone succeeded in getting such an app accepted on the Mac App Store when it includes sensor-level, private API access like this?
What were the reviewer feedback or rejection reasons (if any)?
Are there documented cases (positive or negative) where Apple approved or rejected apps for accessing non-public hardware sensors?
What’s the risk of getting banned or permanently rejected for integrating this kind of functionality?
If you have direct experience (whether it passed or failed), I’d love to hear your stories, strategies, or pointers. Thanks in advance!
There's a recent response by one of my colleagues that addresses this.
