Thank you @Sam_Garfield! I was able to reproduce this on an M1 Mac in ARDK 1.2.0. I should also note that building the remote feed app on the M1 didn’t appear to be the problem. But connecting to the Unity editor running on an M1 device did produce the error. > [@Sam\_Garfield](#): > > The mesh appears in the editor, but the feature points appear on the phone. Not sure if that is what is intended. You should also see the camera feed in the editor when it is working correctly. ---

I also wanted to add that this appears to be specific to the remote feed app connecting to the Unity editor when running on an M1. The [issues with mock mode](https://community.nianticspatial.com/t/system-dllnotfoundexception-todo-does-not-exist/1005/5) in earlier versions of ARDK have been resolved. ---

A bug has been filed, thanks again! FYI for M1 users that are on a native Apple Silicon Unity build such as 2021.2.16f1 (Apple Silicon), the error will be slightly different: ```auto DllNotFoundException: ardk_client_platform assembly: type: member:(null) Niantic.ARDK.AR._VideoStreamHelper._DecompressForVideo (Niantic.ARDK.AR.CompressedImage compressedImage) (at Assets/ARDK/AR/_VideoStreamHelper.cs:89) ``` ---
