Ultralight Quick Start Metal Error

[tsur]

Hi guys,

I was able to build the project on MacOS v10.13.6 with metal support and everything was fine but cannot run it

2020-04-07 18:24:42.943 MyApp[4705:41918] 
Failed to create pipeline state, error Error Domain=CompilerError Code=1 
"Function fragmentShader has a deployment target which is incompatible with this OS."
UserInfo={NSLocalizedDescription=Function fragmentShader has a deployment target which 
is incompatible with this OS.}
Illegal instruction: 4

most probably related to metal version, should I update to a higher MacOS version? I'm also assuming only Xcode command line tools are required but not whole Xcode, any help is welcome

I tried setting the MACOSX_DEPLOYMENT_TARGET env var also updating the CMakeLists.txt with set(CMAKE_OSX_DEPLOYMENT_TARGET "10.13" CACHE STRING "Minimum OS X deployment version") but still not working, looks like it is required XCode and SDK (not just the command line tools)

thanks so much

Yes it says that the deployment target is targetting higer mac OS, so you must update.

On the Prerequisites page for Ultralight at https://docs.ultralig.ht/docs/installing-prerequisites it says that the program should work with macOS (Sierra or later). I am working on a MacOS High Sierra system and getting the error:
