Remember the cool window shrinking feature in macOS? Today my fully loaded laptop turned off during a meeting, the entire battery drained in about 90 minutes. Because when I disconnected it from my external display on my desk to go to the meeting, the window shrinking feature kicked in and turned one backgrounded window into the pictured state. I’m not sure if the flickering is the fault of iA Writer or the OS, but it is quite impressive that it manages to burn through a almost brand new battery so quickly. And so efficiently that the fans didn’t even alert me to something being wrong. It just works!
