You can then do whatever you're gonna do without Gatekeeper running train on your shit.

Re-booted and reinstalled the Zoom L-20 drivers as per the manual. Only one other USB device (a mouse) is attached to the iMac. Hardware: Zoom Livetrak L-20 with the most recent firmware from Zoom (v1.14). I also found that I could disable security via terminal by typing: Here's my setup and what I have tried so far: Using Ableton Live 10 Suite on MacOS Catalina 10.15.4. vst, but macOS had to be sure I was actually capable of opening the file before they'd grant security permissions. There is absolutely nothing that a doc reader is gonna do with a. vst in Atom (a notepad-type text viewer). Long story short? I opened that son of a bitch. vst was being opened by something, and wasn't registering Ableton as 'opening' it. If it does, unlock the page and hit 'Allow Anyway.' The problem with Neutron was, macOS wanted to see that this. Watch the 'Allow apps downloaded from:' section and look for the app to pop up there. Catalina's Gatekeeper is super annoying with some VSTs and when it tells you a developer cannot be verified, you can head over to System Preferences > Security & Privacy > General tab. Most programs work for me but I had trouble with Neutron 2.
