Q: Fan almost always running since installing macOS Sierra and MacBook Air running hot.
Hi,
Since upgrading to macOS Sierra last night on my MacBook Air (2013, i7, 8gbRAM) the fans are almost always running, even when I am just using Safari. Previously, the fans would only run when I was playing a game, or video editing. The base of my Macbook Air is also much warmer than it was under El Capitan - again, just when using Safari. As a consequence of this, my battery life is now appalling - dropped from 100% to 23% in just over an hour. Again, under El Capitan, if I was just using the internet, an hour's use would see the battery drop 10-15% maximum.
I turned off my Macbook Air, and turned it back on again after fifteen minutes, but within about 10-15 minutes, the fans started back up again and the base (and top of the keyboard) heated up again. Not to uncomfortable levels, but certainly to noticeable levels.
Just to reiterate - I am only running Safari when this happens. Also, since starting this question 5 minutes ago, the battery % has dropped from 29% to 22% and the fans are whirring alway like the dickens.
Any idea why this might be happening?
MacBook Air, macOS Sierra (10.12)
