The per-app volume mixer macOS forgot to ship
mactooloud is an innovative macOS utility that transforms the way users manage audio across different applications. Unlike the built-in system volume control, which adjusts the overall sound level, mactooloud offers per-app volume mixing, giving users precise control over individual app volumes. This is especially useful for professionals and casual users who want to fine-tune their audio environment—whether reducing Chrome's noise without affecting Spotify or balancing multiple communication tools during a busy workday. Its seamless, native menu-bar integration ensures a smooth experience without the need for audio drivers, kernel extensions, or virtual devices, making it lightweight and easy to use. Additionally, features like Auto-Duck for automatically lowering music during calls, the Mystery Sound Finder for locating elusive noises, and Focus mode for isolating one app enhance productivity and usability. Compatible with macOS 14.4+ and available with a 7-day free trial, mactooloud is an essential tool for anyone looking to elevate their audio management on Mac.
