MainStage
MainStage is Apple’s live performance app for Mac, built to run software instruments, effects, backing tracks, and MIDI control on stage.
What is MainStage?
MainStage is a macOS music and audio app for live performance. It helps keyboardists, vocalists, electronic musicians, and other performers turn a Mac into a stage-ready rig with software instruments, effects, backing tracks, and flexible hardware control. Users can build concert setups with patches, layers, splits, and screen controls, then switch sounds during a performance without interrupting audio output. MainStage is also designed to work with Logic Pro content and compatible Audio Units plug-ins, which makes it useful for bringing studio sounds into rehearsals and shows. On Mac, it is commonly used to manage keyboards, vocals, MIDI controllers, foot pedals, and playback in one performance workspace.

Safety overview
Status: Safe
MainStage is legitimate Apple music software for macOS. Access to audio inputs, MIDI devices, external storage, and similar resources is consistent with its live-performance purpose. As with other audio apps, review microphone and file access if you use the app on a shared Mac, and install updates through Apple to receive fixes and compatibility improvements.
Recommendation: Keep MainStage if you use your Mac for live performance, rehearsal, keyboard rigs, backing tracks, or MIDI-controlled shows. If you no longer use it, you can remove the app to free storage, but projects, sound libraries, and related content may need separate cleanup if you want to recover additional space.
