Compiling on Mac - Weird Warnings not seen on Win64

My co founder is trying to get our project going on his mac, stock ue4 install, xcode installed, nothing set (new to UE4, but very experiance with cpp) and he gets these warnings on just ocean files when compiling any ideas?

Ocean Project warnings XCode Mac 10.x - Pastebin.com - Compile log with warnings, but no errors. Then the project fails to compile.

No problems on PC for either of us so repo/source/etc is fine AFAICT.

There seems to not even be a log file generated, thats as much of the warnings/fail compile as can get before the UnrealBuiltTool closes.

I should note it works for other win users fine as well, anything mac special we should know about, cant find anything in the documentation.

He even went through this answer for 4.12 to no avail New Project will not compile on Mac OS 10.5.11 xcode 7.3 - Platform & Builds - Unreal Engine Forums

Edit: finally got a full log inside of xcode, really weird errors i cant pin it down to anywhere to start.

We thought it might be the Point.h in CashGenUE plugin which mac also has a Point.h file so we renamed all Point instances and file to S_Point but no go.
