With all of the new features packed into iOS 11, High Sierra is something of a disappointment. It’s a bit like getting socks and underwear for Christmas. You know it’s necessary and you’ll be happier six months from now when you don’t have to walk around with your toes poking out of holes, but for now, you wish there were a few more video games and action figures mixed in with the bunch.

That’s partially a result of a yearly upgrade cycle — Apple can’t reinvent the wheel each time out. But more than that, this latest version of macOS is about rebuilding the software’s foundation. There are a few surface level enhancements, most notably to Safari and Photos, but the fundamental updates to the operating system are almost entirely below the surface.
