+M1 Mac build wheels natively
+----------------------------
+
+In order to run DepthAI natively on M1 Mac, you currently need to build the wheels locally. We will add pre-building M1 wheels

+This tutorial was provided by whab and tested on a MacBookPro M1 Pro running macOS Monterey 12.1 with a OAK-D-Lite.
