Collections duplication is binding them together and not allowing for individual selection of the new collection
Short description of error
If you duplicate a collection you cannot individually modify the new collection as it's tied (mirrored?) to the previous one.
Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).
Create a set of objects, in the collections tab select a collection and duplicate it. If you toggle the visibility of the first collection off the newly duplicated collection will also be toggled on/off. Each object is mirrored to the original and cannot be modified individually. Even if this behavior is intentional it's extremely bizarre.
-Also small note: The Z key in edit mode on Mac is opening a shading pie menu by default instead of giving the option to enter wireframe. On the windows version I am not having this issue. Both copies of Blender 2.8 are fresh installations with no preference modifications yet the keybinds are acting differently.
