eqMac vs Hidden Bar

eqMac is a system-wide audio equalizer and volume mixer for macOS. The free tier includes basic bass, mids and treble controls and a fixed 10-band equalizer. AutoEQ provides automatic headphone equalization from frequency responses, with support listed for 4,600 headphone presets. Pro adds unlimited customizable bands, a real-time spectrum analyzer, separate left and right channel EQ, AudioUnit hosting, spatial audio and per-application volume mixing. The maker says its driver captures system audio and passes it to the app through a secure memory tunnel for processing; it also says the driver runs in user space rather than the kernel. Downloads are listed for macOS 10.13 or later on Intel and Apple Silicon. The maker lists a free HTTP API for controlling eqMac, and remote control from iOS, iPadOS or Android devices on the same local network as a Pro feature. The free plan has no Pro features. Paid access is listed from $1/mo, while the Pro subscription page does not state a yearly price. Public GitHub code corresponds to version 1.3.2 without Pro features; newer releases are developed on a private fork.

Hidden Bar is a free, open-source macOS app for hiding menu bar items. Click its arrow to expand or collapse the hidden section, and Command-drag icons across the divider to choose which items it hides. Preferences include automatic re-collapse after a selected delay and a system-wide shortcut. An optional second section stays hidden even when the main section is expanded; Option-click the arrow to reveal it. The app can launch at login through the macOS 13 or later SMAppService login item. It is available through Homebrew or manual download, and the project describes its direct download as notarized. The listed plan is free. On macOS 27, the direct download requires Accessibility permission to detect icon positions; hiding is per app, built-in macOS items remain visible, and the app must run from /Applications. That hiding feature relies on a private Apple framework that a macOS update could disrupt.
