Im using Xcode 11.3.1 SDK trying to target El Capitan (other mac).. using Core Audio/MIDI dependancies in OSX. At first it said "You can’t use this version of the application “Xamarin Studio.app” with this version of OS X.
You have OS X 10.11.3. The application requires OS X 10.13 or later.
I have changed the Deployment Target to 10.11 but I either still get the error or it says "You can't open the application because it may be damaged or incomplete"

I would check your console logs to see if they have more information. This error:
could be due to code signing, not having the right version in your info.plist, or a number of other sources. Without more information, it's hard to pin down.
How do I view the "console logs"? The El Capitan mac has no Visual Studio on it.. just the app?
