Update to the above, it needs doing every time MacOS is updated (I just went to macOS Big Sur v11.5.1 on an Intel Core i5 iMac) Bit of a time-consuming pain.
Line 6 have a damned cheek claiming that the HD ProX works with Hd ProX Edit (and, de facto, my Logic Pro Software), especially when they are still selling the product. I, for one, will NEVER buy a Line 6 product again. I have other kit (Kemper Profiler, Mooer GE300, and they worked FLAWLESSLY with MacOS updates. Line 6 are only concerned with selling their latest products and not supporting older (but still being sold!) ones... Not to inflame a pointless debate but I had a Helix but sold it again, as I thought the amp modelling and in particular, the effects sounded a bit naff (compared with my much older Eventide stompboxes). I still wanted a one-stop shop pedalboard solution and I couldn't be happier with the Kemper. Each to their own, I realise that lots of you will be very happy with your Helix. I just think Line 6 support is sh**e
