Important Information for macOS Users: Possible Issues with NESS After Recent Security Updates

The latest macOS security updates may cause minor disruptions with NESS. For example:

  • If NESS repeatedly asks for your license file on every restart.
  • If you don’t see any impulse responses in the dropdown menu of the Reverb tab.

This likely means NESS is running in quarantine mode.

How to check:

Press cmd+shift+M to open the console. If you see errors with file paths containing the term “translocation”, it confirms that NESS is being launched in isolation.

Simple Solution:

1️⃣ Open the Terminal.
2️⃣ Enter the following command:

xattr -r -d com.apple.quarantine path/to/NESS.app
