Hi, It might be advisable to have a look at this - page 7 has a diagram of the HX One in an Amp FX Loop, plus other options, including 4CM which mentions pre and post settings. https://line6.com/data/6/0a0004220039697155cf001b7/application/pdf/HX One Owner's Manual - English .pdf more diagrams here:- https://line6.com/data/6/0a00050b05f066312d3e0bd6e/application/pdf/HX One Cheat Sheet - English .pdf Hope this helps/makes sense.

Do not use v1.8x,... there was glitch in it where, if you tried to update later from there, you have a 50/50 chance of locking up the program board (bricking it), making it non functional. At that point, I would have less than a 50/50 chance of bringing that board back to life with the tools I have here at Line 6. So Do not use v1.8x.

I was able to get this working in Mac OS 26.1 Tahoe on a Mac mini M2. Here's what I had to do: Start the Mac in Recovery mode. This took probably 5 minutes Power off your Mac Hold down the power button until you're prompted to select either your boot drive or Options Click Options Wait a bit while it scans your disk In the top menu go to Utilities...Startup Security Utility Select the system on which you want to install the Driver. If the disk is encrypted with FileVault, click Unlock, enter the password, and then click Unlock. Click Security Policy, choose Reduced Security and check the option to allow user management of kernel extensions from identified developers Click OK. Enter the password for your account and click OK. Restart your Mac from Apple menu Download the Line6 Driver here: https://line6.com/software/readeula.html?rid=11477 Install the driver Run the following from a Terminal window (you can press CMD + Spacebar to search for Terminal if needed): sudo kextload /Library/Extensions/Line6AudioUniversal.kext Reboot the Mac I hope that helps!
