MaCursorMaCursor gives you control over the system cursors on macOS. You can replace them with your own artwork or with ready-made themes, fine-tune every detail in a visual editor, and switch between themes instantly with global hotkeys. The Theme Gallery offers more than 80 ready-to-apply themes, and a double-click on a theme replaces every system cursor. A Restore button puts the macOS defaults back at any time.Customization
MosMos makes scrolling with a mouse wheel on your Mac feel as smooth as a trackpad, while keeping the precision of a mouse. On macOS a mouse wheel often scrolls in abrupt jumps; Mos intercepts the wheel events and turns them into smooth, continuous movement. It also lets you set the scroll direction for the mouse separately from the trackpad, so you can keep natural scrolling on one and not the other. Mos is a small menu bar app made by Caldis and loved by more than 21,000 people who starred it on GitHub.Customization
Karabiner-ElementsKarabiner-Elements is a free, open-source keyboard customizer for Mac. It can change any key into another, such as Caps Lock into Control or Escape, and with complex modifications it can do much more: make a key act as Escape when tapped and Control when held, add a "hyper" key, or set different rules for different apps and keyboards. Karabiner-Elements is made by Takayama Fumihiko (pqrs.org) and released into the public domain.Customization
WindowCycleWindowCycle is a window switcher for the app you are using right now. Press Command + ` and a panel lists the windows of the frontmost app; keep pressing to move forward, add Shift to move back, and release Command to bring the selected window to the front. Escape hides the panel, and a menu bar item offers Show, Hide, Settings and Quit. Unlike the built-in shortcut, you can see every window of the app before you pick one.Customization
LeftHandyLeftHandy is a small menu bar app that adds left-handed mouse and cursor support to your Mac. It mirrors the system cursors, including the arrow, the pointing hand, the resize handles and the crosshair, so their tip points the way that feels natural to a left-handed user. It can also swap the left and right mouse buttons in real time, without changing anything in System Settings.Customization
NocturneNocturne is a small menu bar app for Mac that stops the menu bar clock from telling you how late it is. macOS offers no switch to hide the clock, so Nocturne makes it unreadable instead: in its default Blind mode it turns the clock into a small analog dial, so the time is still there but your eye stops catching it. Other modes go further and blank the clock, the whole menu bar, or every icon except the clock. Clicks still pass through, and Nocturne keeps its own moon icon visible so you can always switch back.Customization
PlonkPlonk is a free, open-source toolbox for the Mac that puts a set of everyday utilities behind one menu bar icon. It arranges windows in snap zones you draw yourself, saves workspaces that put apps back on the right monitor, takes and annotates screenshots, copies text from anything on screen with on-device OCR, measures the screen in points and pixels, keeps the Mac awake and adds pointer tools. Every tool shares one interface, one command palette and one set of settings, and each module except the shortcut guide can be switched off.Customization
TinkerToolTinkerTool is a free utility that gives you access to additional preference settings Apple has built into macOS but does not show in System Settings. With it you can switch on hidden features of the operating system and of some apps that come with it: show hidden files in the Finder, add spacers to the Dock, change the screenshot file format, turn off Liquid Glass or keep chosen apps light while dark mode is on. Every change applies only to your own user account, and all settings can be reset to Apple's defaults or to the state before you used the tool.Customization
DeckleDeckle is a free, open-source menu bar app that lays a subtle paper-grain texture over your entire Mac screen. The idea is to make long reading and writing sessions feel more like paper than glass. You pick a paper, set how strong it is, and keep working: the overlay is fully click-through, so every window underneath stays usable. It comes with 26 built-in papers, from a plain dimming veil with no grain to warm, tinted, dark and fiber-heavy finishes, and you can save up to eight named desk setups such as Read, Write or Unwind.Customization
NudgeNudge is a free, open-source window manager for the Mac. It lives in the menu bar and lets you snap windows into halves, quarters, thirds and two-thirds, maximize or center them, or restore their previous size with a keyboard shortcut. You can also drag a window to a screen edge or corner to snap it into place, so arranging a desk full of apps takes a keystroke instead of careful resizing.Customization
NotchlyNotchly is a lightweight native app that turns the notch on a MacBook screen into a small, interactive control area, similar to the Dynamic Island on iPhone. Around the notch it shows what is playing with music controls, battery and charging status, Lock Screen playback, focus mode animations and swipe gestures. For developers it can also show alerts from Codex, Cursor and Claude Code, so you see when an AI agent needs approval or has finished a task.Customization
Application MenuApplication Menu, also called app-menu, adds the missing Applications menu to macOS. It puts an icon in the menu bar, and clicking it shows a menu of the apps in your Applications folder, so you can open any of them without going through Finder, Launchpad or Spotlight.Customization
Window GlueWindow Glue is a small macOS menu bar utility that lets you glue two windows together so that they behave, mostly, as one. Turn on Add Glue from the menu bar icon, drag a window near another, and a glow shows where it will snap. Once they are joined, moving one window brings the other along. Shake a window quickly to break the connection.Customization
DockitDockit is a small macOS window management tool focused on one job: docking windows to the edge of the screen and previewing them quickly. Send a window to the left or right edge and it tucks away, leaving a sliver showing. Move the pointer to that edge and the window expands, then it retracts when you leave. It is useful for a window you check often, such as notes, a chat or a terminal, without giving it a permanent place on the screen.Customization
SlimHUDSlimHUD replaces the overlays macOS shows when you change the volume, the screen brightness or the keyboard backlight. Instead of the system graphic you get a slim bar on the edge of the screen, and you decide how it looks. To open its settings window, start SlimHUD again while it is already running.Customization
Satellite EyesSatellite Eyes is a small macOS app that sits in the menu bar, next to the clock, and automatically changes your desktop wallpaper to the satellite or map view directly overhead. Take your laptop somewhere new and the desktop changes to the view from above that place. You choose from a number of map styles, from aerial photography to abstract watercolors, and with more than one monitor the picture spans across the full width of your screens.Customization
EquinoxEquinox is a Mac app that creates native macOS dynamic wallpapers. macOS has supported Dynamic Desktop and Light and Dark Desktop wallpapers since Mojave, and Equinox makes building your own quick: choose a wallpaper type, drag and drop your images and export the finished wallpaper.Customization
ÜbersichtÜbersicht is a free, open-source Mac app that lets you run system commands and display their output on your desktop in little containers called widgets. Instead of opening a terminal or a separate window, you keep the information you care about in view: what is happening on your machine and in the world, laid out the way you want it. Because widgets are written with web technology, they can show data as tables, charts and graphs, and they can react to different screen sizes.Customization
SaneBarSaneBar tidies your Mac's menu bar. Hide the menu bar apps you do not need right now, keep the important ones visible, and open hidden apps quickly when you need them. Hold Command and drag icons in the menu bar to choose which stay visible, then click the SaneBar icon to show or hide the rest. Hidden apps can be browsed in an Icon Panel, where you can search by name and double-click to open one, or in a second menu bar.Customization
SensibleSideButtonsIf you use a third-party mouse with your Mac, its side buttons (often called M4 and M5) do almost nothing useful by default. On Windows they move back and forward in nearly any window with a history. SensibleSideButtons brings that to macOS: your side buttons act like the three-finger swipe on a trackpad, so you can go back and forward in Safari, Finder and almost any other app with a history.Customization
PhosphenePhosphene lets you use your own videos as wallpapers on macOS. It adds them to System Settings → Wallpaper through the same system that plays Apple's Aerial wallpapers, so you pick a video there just like a built-in wallpaper, and macOS plays it on the desktop and the lock screen, even after you quit Phosphene. Drag a video into Phosphene's library or onto its menu bar icon, then choose it in System Settings. It plays MP4, MOV, HEVC, H.264, ProRes and other formats your Mac can decode, with gapless looping.Customization
MiddleDragMac trackpads have no middle mouse button, but many apps expect one. MiddleDrag adds it with three-finger gestures: a three-finger tap is a middle-click, and a three-finger drag is a middle-drag. Use it to open links in new background tabs and close tabs in your browser, pan the canvas in Figma or Photoshop, close editor tabs in code editors, and orbit and pan the view in 3D apps such as Blender, FreeCAD and SketchUp. Mission Control and other macOS gestures keep working.Customization
OnlySwitchOnlySwitch puts everyday macOS controls into one customizable menu bar app. Instead of digging through System Settings or typing Terminal commands, you click a switch: hide desktop icons, change appearance to dark mode, keep the Mac awake, show hidden files or the Finder path bar, connect AirPods or Bluetooth, empty the Trash or the clipboard, clear the Xcode cache, and more. You can add, remove and reorder switches, import your macOS Shortcuts, give any switch a keyboard shortcut, and place controls on the desktop as widgets.Customization
MiddleClickMiddleClick adds the missing middle mouse button to your MacBook trackpad and Magic Mouse. Click or tap with three fingers and macOS receives a middle click, just as if you had a mouse with a scroll wheel. That means you can close browser tabs by middle-clicking them, open links in a new background tab in Safari, and paste selected text in Terminal. The app sits quietly in the menu bar, and you can hide its icon if you prefer.Customization
