I think they are holding it because a new mac is coming on 4th, and there is something in 10.13.5 about new Mac that they dont want us to know yet
my thoughts exactly!
Just intuition , there is something in 10.13.5 about new Mac that they don't want us to know yet, could be new macbook, or air or mini, any mac
This wouldn't be necessary. They would just have a special build for the new Mac. They've done it multiple times before.
