>have a hard to find mems accelerometer managed by the sensor processing unit
How did OP even know that an accelerometer exists in the first place?
undocumented
The one thought that comes to mind is this: "Your warranty claim was denied because we determined that the laptop was subjected to a sudden shock."
"hidden", checks API: https://developer.apple.com/documentation/coremotion/cmdevic...
and there is Mac Catalyst (iOS on Mac) and Mac support.
what am I missing ? that this uses a raw stream ?
On my M4 14-inch MacBook Pro, it looks like there are two accelerometers: One with {"DeviceUsagePage"=0xff00,"DeviceUsage"=3}, and one with {"DeviceUsagePage"=0xff00,"DeviceUsage"=9} - They both identify as Bosch BMI286
If it can read your heartbeat from your wrists resting next to the trackpad, maybe it can use that as a user satisfaction signal for gratuitous UI changes.
I would like an app to lock my screen on sudden movement; optionally disable TouchID for next login.
I've been wondering about this for a while, glad someone's finally managed to access it.
Could this be used as "shake your mac for highly random seed" bits?
This is so cool thank you!
I wonder if this sensor is used for Vision Pro display mirroring.

Way back in ~2008 I wrote the Newton Virus https://www.everita.com/how-the-newton-virus-was-made + https://www.youtube.com/watch?v=eh75j6OHhRc (sorry for the broken images, need to update that site). Between that and using a hidden API to take screenshots of each individual element on your desktop (from icons, to taskbar, to windows) the effect was pretty believable. One of the most fun (and frustrating) projects I ever worked on.
