definitely fixed for me .. tried everything to make it NOT work, and it works as any Mac I've used in the last 15 years now .. I don't know if my exact model (MBP 14inch base model + upgrade to 1TB) has to do with anything,That's very interesting - with my 14" with 12.5 it's still very much a problem, and possibly worse than it was with 12.4. Baffling.
but I'm 100% it works perfectly now ..
