Upgrading to newer versions of Macos, greater than 11.0 or in my case migrating to a new M1 mini presented a few challenges, especially for Arduino IDE. Here it is, step by step to get both platform IO and Arduino IDE up and running on the new OS notably with ESP32 , especially where the transfer of code to the device is concerned. Version 11.2 of MacOS is used in this example on a brand new installation.
The video that covers the installation of Platform IO. This video explains the minor change in procedure top the installation of the VCP drivers as covered below.
