Tried the workaround. The menu options seem to have changed under Sonoma 14.3. Under privacy and security there is no "general" category. Did see another note about installing rosetta 2 since HD Edit was written to run on Intel Macs and rosetta 2 is an emulator that allows these apps to run on the new M1/M2 Macs. Received this message after attempting to install ; " rosetta 2 not supported on this version of Mac OS". Don't know for sure if this has anything to do with the OS not recognizing the HD500X, but my next query is to Apple to see if Rosetta 2 has been discontinued or they just forgot to include it in the 14.3 build. Would be nice if Line6 could weigh in on this question.

So does that mean the HD500X will never work with Sonoma 14.3 or later, or is there a workaround ?

After many attempts, my new Macbook Air M2 does not recognize my HD500X when connected. Everything still works fine with my old Macbook Air (2012). Apps that no longer work: HD500X Edit, Mainstage, Garage Band. So I am thinking it is some sort of driver issue. Are there any known issues with HD500X drivers and the new Macbook M1,M2 running Sonoma 14.3 ?

Same issue here. Of course the issue is you can't go back to an earlier driver if you have already upgraded the OS X to Yosemite, because of the 10.1 vs 10.10 issue. This should be a very easy fix for Line6 to accomplish. Their silence on this matter is deafening and inaction is disturbing. I own a bunch of Line6 products and my Pod X3 is only 5 years old. I would expect Line6 to do the right thing for their loyal customers.
