The “Edit Scheme” option showed a default build configuration of Development Editor. Changing it to Development results in a successful build, though the built program displays the following startup message and exits after showing the pop-up window:
The global shader cache file '/Users/Shared/UnrealEngine/4.10/Engine/GlobalShaderCache-GLSL_150_MAC.bin' is missing.
Your application is built to load COOKED content. No COOKED content was found; This usually means you did not cook content for this build.
It also may indicate missing cooked data for a shader platform(e.g., OpenGL under Windows): Make sure your platform's packaging settings include this Targeted RHI.
Alternatively build and run the UNCOOKED version instead.
Changing the build configuration to DebugGame results in the same pattern of a successful build followed by an error message on startup. Same thing for the Shipping configuration. In any event, thank you for the (partial) fix anyway! I’ll have to see where I can change the settings to make the program load uncooked content.
