Will ClipMic work on my Mac or PC?

No.

Original ClipMic units are designed with a Lightning connector to plug into any iOS device with a lightning port (iPhone, iPad or iPod touch), but will not connect to a Mac or Windows computer with any lightning to USB adapters.   

Original ClipMic models will not work with lightning to USB C adapters to connect to iOS devices with USB C ports (iPad Pro, etc)

ClipMic 2 units are compatible with Mac, Windows and iOS devices with lightning and USB C ports.
