Interesting. Okay, more searching turns up the “xcrun” and “xcode-select” tools, which confirm that I am in fact using a 10.15 SDK:
hardy:~/430 clements> xcrun --show-sdk-version 10.15 hardy:~/430 clements> xcode-select -p /Applications/Xcode.app/Contents/Developer hardy:~/430 clements> xcrun --show-sdk-path /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk What I’m less sure about is how to set it *back* to 10.14 so that I can compile racket again. Things I’m seeing online suggest that in fact this might involve downloading another whole copy of XCode, which would be … a bit frightening.
