I just retied and it worked out of the box. Don't know what the error was, I did not change nothing.

MacOS – “macOS Sierra Update” could not be verified

I was able to update by using the combo updater for 10.12.3. The DMG file can be downloaded outside of the App Store and I can explicitly know that the file is good because it verifies itself.

MacOS – Dual boot macOS Catalina 10.15 beta and macOS Mojave 10.14

Your existing installation won't be blindly updated. The macOS 10.15 Catalina beta installer will launch as soon as it is downloaded.

You can create a bootable USB installer by plugging in a USB flash drive and running the following in Terminal:

sudo /Applications/Install\ macOS\ 10.15\ Beta.app/Contents/Resources/createinstallmedia --volume /Volumes/DRIVE

where DRIVE in the name of your external USB drive

You can choose to install macOS Catalina on an external drive, if you don't wish to interfere with your current installation.
