Greetings,
Just downloaded the Redux 1.4 demo for MacOS and found a little issue with Intel based Macs - yes, there are a few of us left 
Upon starting Redux → Editor → Phrases → Create Phrase → Edit, I’d see a “Lua Language Server failed to load” modal dialog.
Checking /Library/Audio/Plug-Ins/VST3/Renoise Redux.vst3/Contents/Resources/3rdParty/LuaLS/bin, it looks like the lua-language-server-mac_x86_64 file was missing an execution flag (the arm one is obviously there)
-rw-r–r–@ 1 nazar staff 1252160 8 Jul 14:34 lua-language-server-mac_x86_64
A chmod a+x lua-language-server-mac_x86_64 fixes this.
Leaving this here incase it helps someone but I’d recommend setting the execution flag on that file for future releases.
All the best!
