Q: Mac El Capitan and Update Issues

Hello All,

I come to you with an issue. I am running El Capitan 10.11.5...

But in the App Store it will not allow me to update to 10.11.6...  It just says calculating and it never does anything. I even left it overnight and it just hangs.

Here is what I do...

I choose Update All then the prompt Download and Restart...

Then this goes on forever:

Has this happened to anyone? If so. might I inquire if you found a fix?

Many Thanks,

DA
