Catalina Installation Warning dialog

[James Sentman]

Good morning George!

That is a USB/Serial adaptor driver for an adaptor that is using a Silabs chip. They are popular enough that I’m sure they have or will have a catalina approved driver you just need to download and install the latest version from them and see if the warning goes away. If they don’t update it in a timely manner you can pick up an FTDI chip based USB/Serial adaptor to replace the one you’re using for under $20. Those have a driver included with MacOSX now days so there is nothing you have to install at all to use them. 

The driver and the warning aren’t specifically part of anything XTension, just the USB/Serial adaptor that you’re probably using for the XTB232.

the “Install USB Driver Support” menu item on OSX will likely not work on Catalina anyway, and will likely never work on Catalina. What it does is install the kernel extensions that let the system recognize the couple of USB to X10 adaptors that we have supported over the years. It installs a driver for some older and not available anymore smarthome USB powerline modems that could do X10 as well as X10’s CM19 and CM15 devices which were USB also. It is unlikely that any of those devices will ever be supported going forward to Catalina as they certainly aren’t going to write new drivers for them, I am not going to join Apple’s kernel developer program and try to write my own for them based on the new system as none of them are available anymore as far as I know. If anybody has one of those things as a part of their system they should replace them before they want to update to Catalina as they will not work anymore and XTension won’t be able to talk to them.

Any just regular serial device like the MR26 or CM11’s or the XTB232 will still work as long as you have a USB/Serial adaptor that is supported. Devices that are USB but just have an embedded FTDI serial chip like the RFX transceivers will continue to work as well since they are not a custom USB device but just have their supported serial adaptor on the board.

Thanks,
