File won't transfer between Windows and Mac

I am trying to open my friend’s project file. He created it on a Windows and I am trying to open it on my Mac, is this the issue? First it says “The plug-in ‘BIAS_x64’ could not be found” for all of the channels. Then it shows a big list of missing files. Once it opens it shows all of the channels he used to make the recording but there is no audio.
