How it works
The Dock becomes a control surface.
docktor doesn't try to replace macOS. It sharpens the one place you already visit all day with previews, widgets, and quick info.
Hover
Preview every window for an app before you commit to switching.
Glance
Keep music, meetings, and weather beside the Dock.
Act
Click a preview, pause a track, or check the next event.
Dock Previews
Find the right window before you switch.
Hover an app and docktor turns the Dock into a live window chooser. Real thumbnails, one-click activation, and no need to open Mission Control.
Window Switcher
Cmd+Tab, but you can actually see what you're switching to.
docktor replaces the stock Cmd+Tab switcher with live window thumbnails so you pick the right window on the first try.
Music
Control playback without leaving what you're doing.
The Music widget shows the current track next to the Dock and keeps transport controls one hover away. It works with Spotify and Apple Music.
Calendar
See your next event before it starts.
The Calendar widget reads your Apple Calendar and shows the next event with a live countdown. The drawer holds the rest of the day.
Weather
Check conditions at a glance.
The Weather widget shows current conditions in the bar and a 12-hour forecast in the drawer, using data from Open-Meteo.
System Stats
Keep an eye on your Mac without opening Activity Monitor.
The System Stats widget puts CPU, memory, and disk right next to the Dock, with drawer pages that break down each one and chart the last few minutes.
Device Batteries
Every battery you care about, right next to the Dock.
The Device Batteries widget tracks your Mac and connected Apple peripherals — AirPods, Magic Mouse, Keyboard, and Trackpad — plus Logitech mice and keyboards, so you catch a low battery before it dies mid-task.
