I've tried to find a thunderbolt3 dock that worked perfectly but none have - not even limited to Catalina. My monitors will randomly switch refresh rates or resolutions or not even display picture. Plug them into a pc and they work every single time.
I have Catalina. It doesn't play nicely with a Dell D6000 powerbrick / dock.
The display is fine but it won't charge at the same time.
I have not installed the Dell 'driver'; it loads a kext so probably won't work anyway. I'm not upset about that. Docking should not require a kernel module.
That's about it. Catalina has been fine every other way.
The thing is with this charging bullshit is, it worked fine prior to 10.15.4. Prior to that version, my Mac charged and outputted to multiple screens at the same time.
I actually have one but haven't really used it yet since I decided to just use windows and be done with all the mac problems for now. Still use my MBP but only from the couch.
