When i try to install this update and click restart i get the message "available updates have changed" which prevents the restart.
i also tried sudo softwareupdate -i -a at the terminal but got the message
Finding available software
Downloaded iTunes Device Support Update

Hello, scrollo.
Thank you for using Apple Support Communities.
I understand you're unable to install macOS update 10.13.6. I'd like to help. See if you can either update using safe mode or a test user account:
How to use safe mode on your Mac
How to test an issue in another user account on your Mac
If this doesn't help, try repairing your disk: Repair a storage device in Disk Utility on Mac
Keep me updated.
Cheers!
I logged on to another account as suggested and it said the update happened 10 days ago. Logged back into my own account and it stated the same. Weird but sorted- cheers!
