Installed Xcode on 10.14.2. Created brand-new project from Cocoa template, attempted to build, got the following error:
2019-01-15 11:20:56.277494-0500 Test[7662:553272] [default] Unable to load Info.plist exceptions (eGPUOverrides)
Apple support pointed me at a note advising to add warnings for the camera and microphone to info.plist. Did that, no difference.
The app (such as it is, just the bare template) runs.
Everything runs fine under my certificates on my 10.13.6 machine.
