U3419W, macOS 10.15.6, power chime issue

* macOS Power Chime issue

There is not workaround to solve the incompatibility with the U3419W and U3818DW Ti TPS6598E power delivery chip and macOS 10.14.3 and some later versions. When connected via the USB Type-C to C cable, the macOS user could see the following issues =
- Fully charged Apple MacBook constant "charm" power chime noise due to waking and sleeping
- The monitor might display, "Scanning for Signal"
Dell Policy = A firmware update to the TPS6598E chip will not correct these issues. Also, there will not be a power delivery controller chip upgrade replacement to correct this incompatibility issue. 

The following workarounds can be used =
* Disable sleep on the MacBook. Go to System Preferences --> Energy Saver --> Prevent monitor from sleeping automatically when the display is off
* Disconnect the USB Type-C cable from your MacBook whenever you power off your system
* Use the power adapter provided with your MacBook to charge your system
