Question: 10.13.3

I was able to successfully apply this update to my Mac Mini with no issues, but when I try to install it on my MacBook Pro I just get a black screen with a moveable mouse curser. I even tried to download the installer from the Support site but it is still encountering the same issue. My MacBook Pro is reporting it’s version as 10.13.3
