CP210x USB to UART Bridge VCP Drivers NOT working on MacBook Pro
If still someone is still coming to this forum (as I did today) and does have this problem: for me the normal install worked after I confirmed (after installing) in the system's security settings that SI Labs may put the latest V5 driver on my Mac with Mojave.
I was already asked during install for my admin password but this seemed not to be enough. After allowing access in the security settings it worked for me and Arduino IDE shows port " cu.SLAB_USBtoUART ". This allows now access to my ESP32.
I hope this helps.
