Anyone managed to get RocksmithCustomSongToolkit worked in macOS Sierra (10.12)? I have mono 4.6.0 installed correctly (in /usr/local/bin/mono) but whenever I tried to launch the toolkit, the app icon bounced in the dock for two or three times then disappeared. I'm using the toolkit downloaded from the dropbox link for El Capitan. EDIT: I also tried the newest version of RocksmithCustomSongToolkit, it shows the message about requiring Mono 2.8 or higher.
