Recabinet 5 unpacking its stock IR library has been causing permissions issues for some users of macOS versions that came out after the final update to the plugin. You can easily resolve the issue with the following steps:

1.) Launch the macOS Terminal (located in /Applications/Utilities/ on your boot drive)

2.) Copy and paste the following command into the Terminal, and press enter:

sudo chmod -R 777 ~/Library/Application\ Support/Kazrog\ LLC/

3.) You may be prompted for your macOS user password after entering the command. If the password is wrong, you'll be prompted again. If you get it right, the Terminal will simply return you to a new line.

4.) When you relaunch your DAW, you may need to re-scan any plugins that didn't pass validation.
