Hello,

Previously I had issues with installing v6.0 of the CP210x VCP drivers on Big Sur v11.1. Original post - https://www.silabs.com/community/interface/forum.topic.html/new_cp210x_vcp_driveronbigsur-5icm

Now, after updating to 11.2.3 the drivers are no longer installed in my machine and I get another error when trying to install the drivers I had received from the above post.

Attached is the text from the error screen...

Nam,

That seemed to work without issue! Thank you!

But I wonder if it had something to do with a similar issue with a beta version of a VPN app I was also trying to install. I ended up uninstalling Sophos Home from my iMac and then I was able to successfully install that. ????

Thank you for your help!

Hi Jeff2A,

Thank you for posting your issue. However, we haven't be able to reproduce your issue on our side yet. Our R&D team try to update the driver which give a small tweak to see if it can work on your side. You can find the updated driver in the attachment. Please give it a try and let me know about your result. 

Regards,

Upon installing the new CP210x VCP Driver downloaded this morning on Big Sur macOS 11.1 (on a 2017 27" iMac)  I get this error:
