The July 2019 patch opened up every single environment object to us and I could not be happier! Accessing the objects is very simple. I uploaded a short video showing how to do it, written instructions are below the video:
Bring up the cheat box by holding down CTRL, Shift and C
Type in bb.showliveeditobjects and hit Enter/Return
Click on the search box in the bottom left so your cursor shows but do not type anything. Hit Enter/Return
The catalogue will change to Show All. Scroll down to the bottom then slowly back up to see all the world objects.
You DO NOT need to enter any other cheats. No need for the testingcheats and bb.showhiddenobjects cheats or any others (apart from bb.moveobjects on, that one is always necessary 🙂 ).
Before you rush to install the public beta of Catalina, be aware that the Sims 4 does not currently run in this new OS. This is because of the ActivationUI file which is still 32-bit and 32-bit is no longer supported. EA fixed this in the April ’19 patch but unfortunately had to roll it back in the subsequent hot fix patch as it rendered the game unplayable for all users running 10.7 Lion..
