Hi guys, I don't know why, I had a few pages open at most, and suddenly Safari ate 66 GB of memory. As a result OneNote became unstale and I lost some stuff. After closing Safari, everything including kernel_task went right back to normal which is using just under a GB right now. Is is there a way I can figure out what went wrong at that time? I have attached a screenshot. I am on 10.10.5?
