[Ovmsdev] Problem with Mac OS Mojave

I've been running on Mac OS Yosemite for some time and have avoided updating to newer releases for various reasons, but I was forced to update to Mojave in order to run this year's TurboTax. But that broke my ESP-IDF build procedure: auge25> make clean sh: line 1: 1212 Abort trap: 6 /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -sdk '' -find make 2> /dev/null make: error: unable to find utility "make", not a developer tool or in PATH Have any of you encounted this and fixed it? -- Steve
