Below are macOS and Windows versions of RTcmixShell, an application that lets you edit and run RTcmix scores without having to learn Unix shell commands. This app is very basic and somewhat crash-prone, especially on Windows. Please save your scores often. (for Apple Silicon Macs, macOS 11 or later) (for Intel Macs, macOS 11 or later) (Windows)

Please note that the Windows version of RTcmixShell is not as up-to-date as the Mac one, and it may have trouble with certain audio devices. (You might need to use a different audio buffer size than the default.)

Mac Instructions

You can put this application anywhere on your Mac, but the Applications folder is a good choice.

When you double-click the app the first time, it may ask you for permission to use the microphone. Make sure you give it permission! This affects audio output as well as audio input. If you don’t give it permission, you won’t hear any sound. You should be able to give it permission later by going to System Preferences > Security & Privacy, and pressing the Privacy tab. Choose Microphone in the list at the left, and look for RTcmixShell in the list at the right. Check the checkbox next to RTcmixShell.

When you first try to open a score file, the app will ask you for permission to access the Desktop and Documents folders. It should not ask again after this. These settings are in the same System Preferences tab noted above, but using the Files and Folders item in the list on the left.
