Hello everyone. I have been following this thread with interest and sympathise with everyone who has been suffering these problems. Has anyone considered other factors such as 'dirty mains' / 'dirty power'? There are many external factors that can cause computers to exhibit these issues such as electricity spikes caused by heating boilers switching and fridge freezers, washing machines and kettles. There are also many threads on the web about mobile phones causing these crashes or even wi-fi routers being placed too close to the computer. There are many things to try and eliminate all the potential causes. You could purchase a mains spike counter or mains filter. Dirty mains can be caused inside the home and can come directly from the PowerStation. I feel your pain and just think that there is more some people could do other than wait for the magic OSX update that may never come. It has got to be worth getting a mains power filter as a start.
How would it be a power issue? It happens regardless of being plugged into the wall or on battery. Seeing as how it started with 10.11.4, do you think all these people's power got dirty at the same time?
