Here's how to fix the locked UAD Console plugin presets on a Mac.
Go to ~/Library/Application Support/Universal Audio
Click once on the "Presets" folder then type "⌘I" to open the "Presets" folder's information window.
Click on the Lock icon at the bottom right of that window and enter your Administrator password.
Change all of the Privileges to "Read & Write"
Click on the Gear icon near the bottom left of the window and choose "Apply to Enclosed Items"
When asked if you want to do that say "OK".
You might have to reboot to make the changes take effect.
