@Az-heem Are you saying it works without downloading a driver at all or by downloading the 2.19.0 driver & not doing anything else? Finally, the issue has been resolved with the latest Big Sur update from Apple.  I'm currently running macOS Big Sur version 11.3 (20E232)  and it detected the driver automatically I believe, didn't do anything to get it working.  BlockQuote

I did not have any improvement with MacOS 11.2 (still dropped every 3 seconds), but with the 11.3 Beta the interval went to every 45 minutes to hours. Definitely more usable. My hub is the Razer Core X Chroma & Razer mentions this is an issue and informs that every MacOS user should contact them to "repair" the unit. Besides that not making sense, the support did not know anything about it. I am going to see if a Windows computer can update it since Razer Synapse 3 is not available for MacOS and therefore, one must use a Thunderbolt 3 Windows computer to update it.
