If you're having an issue with an installer and using Catalina then you may be experiencing a bug that was introduced by Catalina, and that has unfortunately caused issues with installers like ours all the way up to huge companies like Dropbox and the like.
If you are having trouble running the installer for your Sunday Sounds product download, you can do the installation manually or check out the video below:
- First double check the MainStage folder is in the correct location: Music > MainStage (If you can’t find the “Music” folder then open the Finder preferences, and under sidebar check the “Music” item. If the MainStage folder is not inside of your Music folder, create a new folder and label is “MainStage”
- Try the installer again.
- If it doesn’t copy over, then open the MainStage folder (Music > MainStage) from the Finder, then drag the two folders from the installer into that opened finder window.
- You should now see Sunday Keys 2020 (or whichever version you are opening) and Patch Builder folders in Music > MainStage folder now. This will match what you see in "User Patches" in the inspector in MainStage.
