MacBook Air - trying to upgrade to El Capitan.  Stuck with rotation of the rotation icon.  I worked on it for nearly 24 hours.

I have a Macbook Air (13 inches, beginning 2014), with Yosemite.  I am trying to download El Capitan, and he is stuck on 'download' with rotation rotation icon in place.  I worked on it for nearly 24 hours.

Press and hold the power button on your Mac, until the screen goes black.

Then follow the instructions to start in Safe Mode

After you reboot under OS X, then try to download El Capitan.

Safe Mode boot removes the system caches that can help when you have problems in OS X upgrade.
