Mac guides

macOS can’t set a different volume for each app; there’s only one system volume. Tuno adds a volume slider for every app that plays sound, right in the menu bar, and remembers it.

Monitors and TVs connected over HDMI or DisplayPort don’t accept volume commands from macOS, so the volume keys show a “not supported” sign. Tuno adds software volume for these devices and makes the keyboard volume keys work again.

macOS has no equalizer that works for all sound. Tuno adds a 10-band equalizer that shapes everything your Mac plays — music, videos, games and calls — with 13 presets and your own.

macOS stops at 100%. Tuno can boost an app’s volume up to 150% or 200%, which makes quiet videos, podcasts and calls easier to hear on MacBook speakers.

Unlike iPhone, macOS has no volume limit. Tuno lets you set a maximum level for each output device, for example 70% for headphones, and keeps the volume from going above it.

Tuno lets you switch the output device with ⌃⌥O, choose devices from the menu bar, set which device should be used when several are connected, and even send a single app to a different output.

macOS has no global microphone mute. Tuno mutes every input device with ⌃⌥⇧M or one click, and shows a red microphone in the menu bar while you’re muted.

macOS plays all sound through a single output device. Tuno lets you choose an output for each app (for example Spotify on your speakers and Zoom in your headphones) and remembers it.

No, macOS has no built-in volume mixer. Tuno adds one to the menu bar: every app playing sound gets its own slider and mute button, and you can choose a separate output device for each app.

macOS shows headphone battery only inside the Bluetooth menu. Tuno lists every connected Bluetooth headphone and speaker with its battery level in its menu bar panel; for AirPods, the left, right and case are shown separately.

The four best-known options are Tuno (free, per-app volume up to 200%, per-app output, equalizer), SoundSource (paid, the most audio effects), Background Music (free and open source, volume only) and eqMac (free equalizer; the per-app mixer is in the paid Pro version).

On Mac, ⌘⇥ switches between apps and brings all of an app’s windows forward. Tuno replaces it with a Windows-style switcher: every window gets its own live preview, the most recent first.

Drag a window to the left or right edge to fill half the screen, to a corner for a quarter, or to the top to fill it. Tuno shows where it will land before you let go, and adds shortcuts for halves, thirds and two-thirds.

macOS doesn’t show window previews in the Dock. With Tuno, hovering over an app in the Dock shows live previews of its open windows; hover a preview to peek at the window in place, click to bring it forward.

On Mac, the red button closes the window but the app keeps running in the Dock. With Tuno, closing an app’s last window with the red button quits the app completely.

macOS can’t change the brightness of most external monitors. Tuno controls it with the brightness keys or a slider in the menu bar: it talks to the monitor directly (DDC/CI) and dims it in software when the monitor doesn’t listen.

Tuno lists every resolution your external monitor supports, marks the sharp (HiDPI) ones, and lets you switch from the menu bar or Tuno › Displays.

macOS has a single “Natural scrolling” setting that applies to both the mouse and the trackpad. Tuno lets you set the scroll direction of each separately, vertically and horizontally.

Wheel mice scroll in steps on Mac, which feels jumpy next to the trackpad. Tuno turns every notch into a smooth, trackpad-like glide and lets you choose how long it lasts.

Side buttons on many mice do nothing in Safari or Finder on Mac. Tuno makes them work as Back and Forward everywhere, or assigns them to Mission Control, desktops, show desktop or middle click.

Tuno shows a short on-screen indicator, in the same style as the volume indicator, whenever Caps Lock turns on or off and whenever the keyboard input language changes.

In Finder, ⌘X doesn’t cut files. The built-in way is to copy with ⌘C and press ⌥⌘V to move them. With Tuno, ⌘X and ⌘V work just like on Windows.

In Finder, Enter starts renaming the selected file, and ⌘↓ or ⌘O opens it. Tuno makes Enter open files, F2 rename them and the Delete key move them to the Trash.

The Mac clipboard holds one item; copying something new replaces it. Tuno keeps your last 50 copies — text, images and files — and opens them with ⌘⇧V so you can paste any of them again.

Tuno’s Keep Awake stops your Mac and its display from going to sleep, indefinitely or for a set time, with one click or ⌃⌥⇧U.

Tuno’s Battery page shows your MacBook battery’s maximum capacity, cycle count against its rated limit, time remaining or time to full, and the charger’s wattage, updated live.

Most things Windows users miss on a Mac can be brought back: Alt-Tab between windows, window snapping, the volume mixer, a red button that quits, ⌘X in Finder, Enter to open files, mouse side buttons and clipboard history. Tuno adds all of them in one menu bar app.
