Industry standard ProTools HD10.3.10, included in all ProToolsHD12 & 2018 licenses, for backward compatibility,
has AAX32 & RTAS
but can also be used with VST & AU with wrappers like: Nugen Sigmod, DDMF, ViennaEnsemblePro 6.0.16068, BlueCatsPatchworks, etc...
PROBLEM:
Latests Operating system is OSX Mavericks 10.9.5
PTHD10.3.10 does Not install in 10.10.x
Helix Native installers only work in 10.10
line6 web page says
AmpFarm Native 4.0
and Echo Farm 3.0.1
should Not work in Mavericks 10.9.5, but ive downloaded installers, and did install.

To install Mavericks, needs to change / unlock the year CPU date, closer to Release date.. 2013 or 2014 maybe 2015 or 2016 or installer will give error, Not login to MacStore when installing, combo upgrade to .5 then works OK, latest Firefox 75.0 works OK, Chrome 67.0.3396.79 & Opera 49.0.2725.64
Focusrite USB interfaces work ok, drivers/control panel v3.4.6 but if control panel is dark, needs to log-out & log-in.
