If you open the same few Mac apps dozens of times a day, hunting for them in the Dock, Launchpad, or Spotlight gets tedious. A hotkey that instantly launches — or brings forward — your browser, notes app, or music player feels like a superpower. macOS does not offer app-launch hotkeys out of the box, but you have two reliable ways to set them up: the free Thor utility, which is built for exactly this job, and a built-in Automator method that needs no extra software at all.
Method 1: Launch apps with Thor
Thor is a tiny, free menu-bar app with a single purpose: opening Mac apps with keyboard shortcuts. It is light, dependable, and takes about two minutes to configure.
- Install Thor. Download it free from the Mac App Store and launch it. A small hammer icon appears in your menu bar, showing Thor is running.
- Launch Thor at login. Open Thor’s preferences and enable “Launch Thor at login” so your hotkeys keep working after every restart.
- Create a rule. In the preferences window, click the + button to add a new shortcut rule.
- Pick the app. Choose the application you want to launch — Safari, Notes, Mail, Terminal, or anything else you use constantly.
- Assign the hotkey. Click the shortcut field and press your chosen key combination, for example Control+Option+S for Safari. Control+Option plus a letter is usually free, but avoid combos macOS already uses.
- Save and test. Close preferences and press your hotkey anywhere in macOS. The app launches if it is closed, or jumps to the front if it is already open.
Repeat the steps for each app you want on speed dial — most people only need three or four. If you are deciding which apps deserve a hotkey, browsing your full installed-apps list is a good way to spot the ones you open most often.
Method 2: The built-in Automator way
Prefer not to install anything? macOS can launch apps from a hotkey using only built-in tools:
- Open Automator and create a new Quick Action.
- At the top, set “Workflow receives” to no input in any application.
- From the actions library, add Launch Application and choose your app from the dropdown.
- Save the Quick Action with a descriptive name such as “Open Safari”.
- Go to System Settings → Keyboard → Keyboard Shortcuts → Services, find your new Quick Action under General, and assign it a hotkey.
This route takes a little longer to set up than Thor, but it relies on nothing but macOS itself. Apple’s guide to creating keyboard shortcuts explains the Services shortcuts screen in more detail, and the Mac keyboard shortcuts reference lists the combos the system already claims, so you can steer clear of them.
If it still doesn’t work
Hotkey does nothing? The most common cause is a conflict: macOS silently ignores a shortcut already claimed by the system or another app. Open System Settings → Keyboard → Keyboard Shortcuts and scan for overlaps, then try a more distinctive combo such as Control+Option+Shift plus a letter. In Thor, check that the app has not been moved or renamed — a rule points at a specific app, so re-add it if you reorganized your Applications folder. For the Automator method, confirm the Quick Action is ticked under Services and that “Workflow receives” is set to “no input”. If shortcuts feel stuck after changes, logging out and back in refreshes the registration.
Frequently asked questions
Will Thor slow down my Mac?
No. Thor is a minimal menu-bar utility that sits idle until you press a hotkey — its CPU and memory footprint is negligible, far lighter than a single browser tab.
Can two apps share one hotkey?
No, and that is by design. Each key combination triggers exactly one rule, so pressing it always does the same predictable thing. If you run out of memorable combos, use Control+Option+Shift plus letters for your less-used apps.
Conclusion
Whether you go with Thor’s two-minute setup or the built-in Automator route, app-launch hotkeys quickly become muscle memory — and going back to clicking the Dock feels painfully slow. Start with your three most-used apps, and once the habit sticks, give your Finder folders a color-coded makeover to keep the rest of your Mac just as snappy. Once your apps open on command, take hotkeys one step further and create custom keyboard shortcuts for individual menu commands in any macOS app.
