Since I upgraded to macOS Sierra on my MacBook 15" (Mid 2014), I noticed some weird behaviour:
- When I'm running low on power, it doesn't notify me that my battery is going to die. It just shuts down. When I plug it in, it takes a few seconds and then shows me the login window, as if I put it on sleep.
- The battery icon doesn't indicate when it is loading
- Whenever my screensaver starts after a few minutes (on power AND battery) it locks my screen (as intended). After entering my password I see that it tried to restart (e.g. "Your mac hasn't restarted, because Google Chrome failed to quit.")
I tried restoring the power settings to default, playing with the checkboxes in the "Energy Saver" tab and so on.
