Since I installed the beta version of macOS Monterey, I get flooded with entries in the console which all say the same line: [default] invalid display identifier Main I have no idea why and what to look for. Any suggestions?

My MTLBuffer is created with the standard MTLResourceStorageModeShared option and I get the pointer to the system memory using the contents method. This works fine on Catalina and Big Sur but my testers on Sierra and High Sierra report that the application crashes. Evaluating the crash reports tell me that the contents method returns a Null pointer. What am I missing? typedef struct KaroMetalLineData KaroMetalLineData; struct KaroMetalLineData{  packed_float2 p1;  packed_float2 p2;  packed_float4 color;  float arg1;  float arg2;  float blend;  int32_t type; }; ...    size_t inputBufferSize = sizeof(KaroMetalLineData) * lineCount; /* is guaranteed to be not zero! */ idMTLBuffer lineInputBuffer = [metal-device newBufferWithLength:inputBufferSize options:(MTLResourceOptions)0]; KaroMetalLineData* localInput = [lineInputBuffer contents];   memcpy(localInput, someSource, inputBufferSize); /* someSource is guaranteed to exist and have enough space*/ ...
