Every Mac tweak you wish you had.
An uninstaller, a cleaner, a task manager, Homebrew, ports, per-app volume and 127 hidden macOS settings, in the same bar. Anything removed goes to the Trash first, with Undo.
Uninstall
The app, and everything it left behind
⌘K on any app, or type uninstall and its name. Saiki finds its support files, caches, preferences and logs, each with its folder and size. You tick what goes, and it all moves to the Trash together.
- ⌘KUninstall… on any app
- ↵Tick or untick a file
- ⌘↵Uninstall
undo uninstallPut it all back
Clean up
Clean what you don't need, and only that
Caches, logs, developer junk and package manager caches come ticked. Old build folders, unused simulators, screenshots and the Trash wait for you. Nothing that's open, still in use or changed since the scan is touched.
- →See what's in a group
- ↵Tick a group
- ⌘↵Clean
Task Manager
End a frozen app, safely
Every app with its CPU, memory, energy, disk and network, live while you look. → opens an app into its processes. End Task asks it to quit like ⌘Q, so it can save; Force Quit ends it at once. Revive brings back an app that stopped answering.
- →Show Processes
- ⌘↵End Task
- ⌘⌫Force Quit
Ports
What's on port 3000, and free it
Every listening port, grouped by project, with its process and framework. Kill one with a key. Homebrew services, launchd jobs and macOS's own processes say why they're left alone.
- ↵Kill Process
- ⌘OOpen in Browser
Port actions
Copy its address, give it a name
⌘K on a port: open it in the browser, copy the port, the PID or the network URL your phone can open, show its folder, or give it a name in Settings so you know what it is next time.
- ⌃⌘CCopy Network URL
- ⌘NName Port…
Sound
A volume for every app
The Volume Mixer lists your output, alerts and microphone, then every app playing sound, each with its own slider up to 200 %. Send one app to your AirPods while the rest stay on the speakers.
- ←→Turn it down or up
- ↵Mute
- ⌘KOutput › another device
Displays
Brightness for every display
Every display's brightness, built-in, Apple or third-party: type brightness and set it from ⌘K, or open its slider in Settings. Night Shift and Extra Brightness are a command away, display modes and arrangements too.
- ⌘1–4Set to 25 % to 100 %
- ↵Its slider in Settings
Keep Awake
Stay awake for an hour, or while agents work
Pick how long from ⌘K, or say it: keep awake until 5pm, keep awake while xcode runs. The menu-bar icon gets a small ring and its menu says until when. It can hold a closed lid too, and Keep Agents Awake stops by itself when your agents are done.
- ↵On until you stop it
- ⌘KFor 30 minutes to 4 hours
System commands
The system's own switches, with a card first
Empty the Trash and see how much goes. Eject every disk and see which app is holding one. Lock, sleep, restart, Dark Mode, hidden files: anything disruptive asks first.
