Feature
A window switcher for macOS, like Alt-Tab on Windows
macOS Cmd+Tab only switches apps, not windows. docktor adds a thumbnail window switcher that flips between every open window — the Alt-Tab behavior Windows users miss on the Mac. Free and notarized.
Cmd+Tab switches apps. This switches windows.
The single thing Windows switchers do that macOS doesn’t: cycle individual windows, not just apps. On a Mac, Cmd+Tab treats your four browser windows as one entry, so you land on the app and then have to find the right window. docktor’s switcher shows a thumbnail of every open window across every app, so you pick the one you want by sight.
Made to feel like macOS, not like Windows 11
The behavior is borrowed from Windows, but the look isn’t. The switcher is rendered in native macOS 26 Liquid Glass, so it reads as part of the system rather than a port. It sits alongside Cmd+Tab — docktor doesn’t disable the built-in app switcher, so you keep both.
The rest comes along
The switcher pairs naturally with docktor’s live Dock previews — hover to peek, switch to commit — and the same app fills the space beside your Dock with music, calendar, weather, and stats. If a configurable, switcher-only tool is what you want instead, compare docktor with AltTab.
Frequently asked questions
- Why doesn't Cmd+Tab switch between windows on a Mac?
- Cmd+Tab on macOS switches between apps, not windows — if you have three Finder windows or four browser windows open, it treats each app as one entry. That's the thing Windows users miss most: Alt-Tab there cycles individual windows. docktor's switcher brings that behavior to the Mac.
- How is docktor's window switcher different from Cmd+Tab?
- It shows a thumbnail of every open window, across all apps, so you're picking the actual window you want by sight instead of tabbing to an app and then hunting for the right window. It's closer to the Windows 11 Alt-Tab than to the built-in Mac app switcher.
- Can I still use Cmd+Tab as well?
- Yes. docktor's switcher lives alongside the macOS app switcher — it doesn't replace or disable Cmd+Tab. Use whichever fits the moment: Cmd+Tab to jump to an app, docktor's switcher to land on a specific window.
- Is the window switcher free?
- Yes. docktor is free and notarized by Apple, with no account and no license. The switcher comes with the rest of the app — Dock previews, and music, calendar, weather, and stats widgets.
