https://devzone.nordicsemi.com/f/nordic-q-a/113112/distinguish-if-hid-device-is-connected-to-windows-macos-pcHi, I am working on a device that is keyboard like, but it just needs to send one cmd to switch the screen - alt+tab/cmd+tab. I was able to get this working with Windows, but now I am struggling with Macos devices.

The device could for example have a Device Information Service (DIS) from which you can read the Vendor ID (VID). If you are not able to find anything about this by researching, I suggest that you reach out to Apple developer support. </p> [quote user=""]Lastly how do I encode CMD button ? For Left ALT modifier is 0x04, but what is value for CMD?[/quote] <p>This question is also more suited for Apple developer support. </p> <p>Best regards,</p> <p>Maria</p><div style="clear:both;"></div>
