People will need a little more information to help you here.
Please list exact versions of your macOS, Blender and RPR installer used.
Generally though you need to have Blender 2.80 Final Release, RPR v2.0.112 (downloaded from AMD.com) and macOS 10.14.X preferably.
Installation works first time for me on the 2017 and 2019 MacBook Pro.
If you get any errors please post them and also a screenshot of what the missing panels looks like would be extremely helpful.
