Seeing this issue on my macbook pro, running Catalina with latest Helix driver installed (1.0.7). The helix device is new, and upgraded to 2.82. Trying to load L6Helix.ext is denied due to invalid signature, as seen in the output below. Anyone able to workaround this issue? I'm hoping once the signature issue is resolved, I could do the "Allow" step mentioned here as the solution, and be happy :-)
$ kextstat | grep -i line6

(kernel) Notice - new kext com.apple.driver.usb.AppleUSBHostPlatformProperties, v1.2 matches prelinked kext but can't determine if executables are the same (no UUIDs).
UPDATE #1: the issue (i.e. no volume control) still persists, even after disabling SIP (as shown here https://www.tonymacx86.com/threads/guide-installing-3rd-party-kexts-el-capitan-sierra-high-sierra-mojave-catalina.268964/page-16), which bypasses the signature check. So, there must be another issue, possibly in the driver?
UPDATE #2: the issue is seen even with driver version 1.0.5 (verified using kextstat that installed version is 1.0.5).
Any advice on how to further debug this? How to verify whether the driver is basically working ok or not, besides the volume control being greyed out?..
Thanks
