Use more than one PS4 Dualshock controller over bluetooth
I've so far been unable to use 2 PS4 Dualshock controllers over Bluetooth with my 2016 Macbook Pro running Mojave. 

Pairing either one with my mac would make the other unable to pair. Renaming the Wireless Controller connection to something more decent did not help.

What helped somewhat was upgrading to the dreaded Catalina - I was able to pair both controllers BUT couldn't play any games with them. The games didn't consistently receive commands from either controller, I was unable to move any of the controlled characters more than a couple pixels on the screen, it was a nightmare. I assumed this was because the controllers kept interfering with one another

What totally helped was replacing one of the PS4 controllers with an XBOX One wireless controller. This worked &amp; fixed all issues, we got no more interferences, and the response time was fine. 

Note: all tested controllers were connected wirelessly via BT, games used were Cuphead and Knights &amp; Bikes running on Steam.
