Very very wild guess: it could have to do with GPU<-> Open GL? <-> Pharo call time out issues because the Intel HD 4000 GPU is working at its (officially allowed) upper performance limits with 3840 x 2160 at 30 Hz refresh rate (maximum). OTOH however: 1. I am not a GPU Guru.. 2. It works flawlessly with Pharo 5.0 and before. 3. All other macOS applications also work OK.
If it is a VM issue, Squeak would have the same problem but I don't want to spend time to try this as well.
