My 15" MacBook Pro, running macOS Sierra freezes frequently. This happens randomly, it freezes and only a force-shutdown (hold the power button) works. First, the Beachball just spins, then sometimes a black screen appears without any description or explanation. At this point, other buttons do not respond.
I tried DiskUtil, CleanMyMac and OnyX to check the SSD, tried reparing permissions and other decisions. But my MacBook continues to hang, although now a little less.
Please recommend me other programs for testing and troubleshooting. Is my MacBook dying? Which devices can cause this problem?
