Can Update to 10.12.6... Volume Requirements?

[spamurai]

Hello.

So I'm been trying to upgrade from 10.12.1 to 10.12.6 today on my MacBook Pro.

Despite the "About this Mac" section showing 10.12.1, no Update is showing in the App Store and I've checked for unfinished downloads.

So I downloaded the .dmg direct from Apple and when I come to install it, I get this notification:

What do I do?
Really hoping to get xCode 9 up and running.

Thanks.

Problem solved in my other question here.

I needed to install the Combo Update. All installed and working fine now.
