make: *** [qemu-io-cmds.o] Error 1
Hi. The CLOCK_MONOTONIC facility was added in OSX 10.12; the version of OSX you're using is too old to build QEMU on, I'm afraid. QEMU's policy is to support the last two releases of OSX, so at the moment that's 10.14 and 10.15. Compiling on older versions might work, but it also might not, as you've discovered.
