MainStage
MainStage is a Mac live performance app that lets musicians play instruments, run effects, and control stage-ready patches from one rig.
What is MainStage?
MainStage is a live performance app for macOS designed for musicians who want to bring studio sounds onto the stage. It helps keyboard players, vocalists, and other performers build concert setups with software instruments, effects, backing tracks, and hardware controls in one workspace. MainStage is closely integrated with Logic Pro, so users can bring compatible patches and plug-ins into a performance rig and switch sounds during a set without interrupting audio. It supports MIDI controllers, foot pedals, drum pads, and other performance hardware, making it useful for rehearsals, gigs, worship music, and stage productions. The app also includes a large collection of instruments, effects, and sound content for creating layered keyboard parts, processing live audio, and managing patch changes in performance.
Key features
- Perform live with software instruments, audio effects, and MIDI plug-ins.
- Use Logic Pro-compatible patches and plug-ins in a stage setup.

Safety overview
Status: Safe
MainStage is legitimate Apple music software for live performance on Mac. Access to audio devices, MIDI hardware, microphones, files, and sound libraries is consistent with its purpose. Keep normal macOS privacy controls in mind if you use microphones, external devices, or large downloaded sound content.
Recommendation: Keep MainStage if you use your Mac for live music performance, rehearsals, or stage playback. If you no longer use it, you can remove the app to free space, but doing so will also remove access to your performance setups and related sound content unless you keep backups.
