Finding 3 instances of the driver with a Finder search, I wondered which one was the good one. I wanted to uninstall the actual driver 4.0.4 version and replace with the 2.6 version. You suggested the 2.6 version ( USA-19HS Driver (Mac OS X 10.9 to 10.11) and that recalled me that my ante Catalina (Mojave) driver was probably 2.6, not 4.0.4. I downloaded and installed the latest Tripp-Lite driver ( USA-19HS Driver (Mac OS X 10.12 to 10.14.x). I also realized that the installation has extracted a few files and put them in quarantine. After restart, I had no more Mail and process crashes. Went in Recovery mode (restart + CMD + R), installed a fresh Catalina version and restored all my files and setup with Apple's Migration Tool. Not finding the culprit and after many hours and days trying to avoid a new fresh OS installation, I was left with only that option. Then I started experiencing Mail and system process crashes. The Keyspan adapter worked perfectly after without any changes or new driver installation.

Recently, I installed Catalina, a result of Apple's automatic update feature. I was told that there is actually no plan for a Catalina update.

I bought the USA-19HS model because Tripp-Lite's support says that this model is still a good seller and that they intend to support it for many years. I use the Keyspan adapter for home automation with the Perceptive Automation Indigo app. It seems you are one of the few last Keyspan pros out there. It still works with Catalina using that adapter. The ImageWriter itself predates the age of the Mac by about three decades. The above is a scan of an ImageWriter printout of that System Extension. If the next macOS version breaks it, and Tripp-Lite isn't interested in supporting that adapter any more, then we will need to find another product. There is a lengthy explanation it remains installable despite the fact it is neither signed or notarized, but that ability is nearly certain to be removed in the next macOS upgrade.Įxisting unsigned Extensions are likely to be rendered inoperative also all the more reason to not uninstall it.
Hence my recommendation to leave it installed. It should remain installable in Catalina but I have not verified that. I had no trouble installing it but I believe I was using Mojave at the time, which I am no longer using. As you can see it is 64-bit and precedes the age of the Mac by about a decade.
