Hi there! I'm currently new to Mac OS dev (coming from a history of Linux dev). I have an external BT keyboard and a couple keys are mapped differently than my Mac keyboard (§ to ` for example). I'm wondering if it's possible to write a kernel extension that detects the key sent from the BT keyboard and remap the key code. I don't really know whether this is possible and if it is, where to look in the ecosystem. It's a bit different from Linux. Thank you!
