My two Windows builders run just fine AND if I manually run the build script then it also builds just fine on the mac. The process being run is only taking about 5% of the CPU when executed from Buildbot. A build that normally finishes in 5 min. times out after 5 hours!

How are you starting the macOS builder? If you are starting via launchd, what options are you using?

In a similar vein, I was trying to figure out why I couldn't wrap a build in "caffeinate" on an older Mac. Same sort of thing: starting the Buildbot slave from a launchd plist would not work (timeout exceptions when the Mac went to sleep), but running it manually via SSH with caffeinate kept the box awake. (Still trying to figure out a solution for that, but I use that box for streaming music now, so it's asleep less frequently.)
