What macOS gives you, and what it does not
Recent versions of macOS can tile a window to a half or a quarter of the screen: drag it to an edge, or use the Window menu. That covers the easy cases. What is still missing is a way to centre a window without resizing it by hand, a way to throw a window onto the next display, and any way to undo a tile you did not mean to do. Those are the actions people install a window manager for.
PowerClick puts all twelve in one place. Because they live in a radial menu that opens under your cursor, you are never dragging a window across two displays to find an edge that triggers the right zone.
How to snap a window with PowerClick
Window snapping is optional, so it starts switched off:
- Open the PowerClick dashboard from the menu bar
- Go to Settings > ShortClick and turn on Window snapping
- Grant Accessibility access when prompted, or enable PowerClick in System Settings > Privacy & Security > Accessibility
- Open the ring with your keyboard shortcut, or by holding Command + Shift and right-clicking
- Pick Windows in the inner ring, then an action in the outer ring
The action always applies to the window that was frontmost when you opened the ring, which means it will never accidentally move the PowerClick window itself.
The twelve actions
Four halves, four quarters, and four that a plain tiling grid cannot express:
- Maximize fills the screen while leaving the menu bar and Dock alone
- Center centres the window without changing its size, which is the one people miss most
- Next Display moves the window to your other monitor, keeping its relative position
- Restore puts the window back where it was before the last snap
Flick to snap
Once the Windows category is open, you do not need a second click. Hold the trigger, throw the cursor toward the action you want, and release. After a day or two the common ones become muscle memory: the motion is a direction rather than a target you have to aim at, which is the reason radial menus beat lists for a small fixed set of choices.
Why Accessibility access is required
Moving or resizing another application's window on macOS is only possible through the public Accessibility API. Every window manager on the platform works this way. PowerClick reads and writes two attributes on the frontmost window, its position and its size, and nothing else. It does not read window contents, text, form fields or any other app's data.
The feature is inert until you both enable it and grant access, and revoking access in System Settings disables it again without affecting anything else in the app. The full breakdown is on the privacy policy page.
PowerClick compared with a dedicated window manager
If you already use Rectangle, Magnet or Moom, the honest comparison is this. For the common actions the vocabulary is the same, and PowerClick reaches them faster if your hand is already on the mouse. A dedicated window manager still goes further: a separate global hotkey per action, custom grid sizes, edge-drag zones and saved layouts. If you depend on those, keep it.
What PowerClick offers instead is scope. The same shortcut that snaps a window also launches your favourite apps, pastes a snippet, reuses clipboard history and runs a Shortcut, and the same app upgrades Finder's right-click menu. That is one $5.99 purchase rather than two or three utilities.
Troubleshooting
If nothing happens when you pick an action, check the two switches in order. First, Window snapping must be on in Settings, because the Windows category does not appear in the ring at all until it is. Second, PowerClick must be enabled in System Settings > Privacy & Security > Accessibility. If it is already listed there and still does not work, remove it with the minus button, add it back, and relaunch the app. More steps are on the Support page.
