CP210x USB to UART Bridge VCP Drivers NOT working on MacBook Pro

I have installed the latest drivers from the web page https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers

https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers

after the installation when I tried to connect to the serial device by selecting SLAB_USBtoUART at 9600 baud rate my program stops working and nothing works

 

I tried different programs CoolTerm, Arduino, ESplorer each and every program stops working after I try to connect to the device(NodeMCU - esp8266). Can anyone please tell me where I did wrong

 

Here is my system specification:

macOS Sierra v10.12.6

MacBook Pro (13-inch, 2017, Four Thunderbolt 3 Ports)

3.5 GHz Intel Core i7

 

 

Thank you.

As discussed in the following thread, it appears the v5.x SiLabs driver is completely broken.

http://community.silabs.com/t5/Interface/mac-os-10-12-6-and-cp2102/m-p/206785

Fortunately the v4.x driver, which is included in the "Legacy MacVCP Driver" folder in the same download, works fine. Do note that you might have to install it twice for it to work, as the first install will just remove the existing driver. If it's installed, there should be a "SiLabsUSBDriver.kext" file in /Library/Extensions with a date created of June 16, 2017.

 

Can someone from SiLabs look at this?

I have been trying for ages to resolve this problem including using the legacy drivers. All to no avail. Delete this - install that, emails to Davis Instruments and trilogy, chat sessions with Apple and so on and so forth. However having discovered your reply, I tried using your double installation trick and -surprise surprise!! my weather station is once again telling the world it's raining in Northern Ireland. Thanks for your help.
