However, what Akai/InMusic SHOULD have done is indicated clearly on the downloads page of the inMusic website that for Sequoia users, the hardware drivers are available separately in the inMusic Software Center. Instead, I had to find out through a support ticket.
They still function just fine, but you get an annoying pop up occasionally reminding you they wont work in a future OS (they've been doing that since Catalina came out).
But you DO have to boot into Recovery and set the security to allow user kexts, otherwise the system ain't going to do shit with it. I just replaced my MOTU 828x with an RME Digiface in December, and man am I glad that I never have to see that message again. I didn't even bother with RMEs kext extension and went straight for the driver extension and it works great. Little Snitch did the same thing a few years ago, and now when you update it, you don't have to reboot anymore. It just turns off the extension and back on again when its done.
