The 10 Most Common Keyboard Shortcut Conflicts on Mac (and How to Fix Each)

A shortcut conflict feels personal, like something unique to your setup. Usually it isn’t. The same handful of key combinations cause most of the trouble on Macs, because macOS reserves a few of the best combos for itself and every popular utility wants the same ones.

Here are the ten you’re most likely to run into. For each one: who’s fighting, who usually wins, and how to fix it.

A quick primer on the rules, since they explain every entry below:

• Global hotkeys beat menu shortcuts. A system-wide hotkey takes the keystroke before the frontmost app sees it.
• Between two global hotkeys, the one registered last usually wins. That’s why shortcuts tend to break right after you install or update something.
• Remappers go first. Karabiner-Elements and skhd rewrite keys before any of the above happens.

1. ⌘Space: Spotlight vs. your launcher

Who’s fighting: Spotlight (macOS) vs. Raycast, Alfred, LaunchBar, or any other launcher you’ve set to ⌘Space.

Symptom: sometimes Spotlight opens and sometimes your launcher does, or the launcher’s setup screen warns that it can’t register the hotkey.

Fix: turn off Spotlight’s shortcut first. Go to System Settings → Keyboard → Keyboard Shortcuts → Spotlight, untick Show Spotlight search, and then assign ⌘Space in your launcher. The full walkthrough is in how to put Raycast or Alfred on ⌘Space.

2. ⌃Space: input sources vs. code completion

Who’s fighting: macOS “Select the previous input source” vs. autocomplete in VS Code, JetBrains IDEs, Emacs (set mark), and many terminal tools.

Symptom: you press ⌃Space expecting suggestions and your keyboard layout switches instead. It only happens once you have two or more input sources, so it tends to show up the day you add a second language.

Fix: System Settings → Keyboard → Keyboard Shortcuts → Input Sources. Untick both entries, or move them to a combo you don’t use. If you use a Mac keyboard with a 🌐 key, you can switch layouts with that key instead. There’s more detail in the IDE shortcut guide.

3. ⌘⇧5 / ⌘⇧4: macOS screenshots vs. third-party capture tools

Who’s fighting: the built-in screenshot shortcuts vs. CleanShot X, Shottr, Snagit, and similar tools.

Symptom: the system screenshot toolbar appears instead of your tool, or you get both.

Fix: most capture tools offer to take over these shortcuts during setup, but the system shortcuts stay enabled unless you turn them off. Go to Keyboard Shortcuts → Screenshots and untick the combos your tool now owns.

4. ⌘⇧A: Terminal’s man page service vs. JetBrains “Find Action”

Who’s fighting: a macOS Services item called Search man Page Index in Terminal vs. IntelliJ IDEA, PyCharm, WebStorm, and other JetBrains IDEs, which use ⌘⇧A for Find Action.

Symptom: a Terminal window opens with an apropos search for whatever text you had selected.

Fix: Keyboard Shortcuts → Services → Text, then untick Search man Page Index in Terminal. This one catches a lot of developers because Services shortcuts only fire when text is selected, so it looks random.

5. ⌃← / ⌃→: Mission Control Spaces vs. word and line navigation

Who’s fighting: Mission Control’s “Move left/right a space” vs. apps and terminal setups that use Control-arrow to move by word or subword.

Symptom: your whole desktop slides sideways when you meant to move the cursor.

Fix: Keyboard Shortcuts → Mission Control. Untick or rebind the Spaces shortcuts. If you use Spaces a lot, trackpad swipes or a window manager hotkey cover the same job.

6. ⌃↑ / ⌃↓: Mission Control and App Exposé vs. editor bindings

Who’s fighting: Mission Control (⌃↑) and Application windows (⌃↓) vs. editors and terminal apps that use them for scrolling, moving lines, or history.

Fix: same pane as above. Most people who hit this rebind Mission Control to a function key or a Hyper combo.

7. ⌘⇧G: a launcher or clipboard hotkey vs. Finder’s “Go to Folder”

Who’s fighting: any utility that registers ⌘⇧G globally vs. Go to Folder in Finder and every Open/Save dialog.

Symptom: Go to Folder stops working, but only in Finder and file dialogs. Everything else seems fine. HotkeyClash marks this kind as a potential conflict: a global hotkey hiding a menu shortcut that only matters while that app is in front.

Fix: rebind the global hotkey in the utility. Go to Folder is used too often to give up.

8. ⌘⇧V: clipboard managers vs. “Paste and Match Style”

Who’s fighting: clipboard managers that use ⌘⇧V for their history window (Paste ships with it as the default, and it’s a popular pick for the others) vs. Paste and Match Style, which many apps put on ⌘⌥⇧V and some (Slack, Chrome, Google Docs) put on ⌘⇧V.

Fix: decide which one you want to be muscle memory and rebind the other one. A clipboard history hotkey on ⌘⇧V is a fine choice if you know that’s the tradeoff.

9. ⌃⌘Space: the Emoji & Symbols viewer vs. everything

Who’s fighting: the macOS Character Viewer (⌃⌘Space, or the 🌐 key on newer keyboards) vs. launchers, window managers, and dictation tools that want a “Space plus two modifiers” combo.

Fix: if you open emoji with the 🌐 key or fnE, you can let a third-party tool have ⌃⌘Space. The Character Viewer shortcut is a menu shortcut (Edit → Emoji & Symbols), so a global hotkey on the same combo will hide it.

10. ⌘⌥D, ⌘⌥Space, ⌃⌘Q: the ones you forgot macOS owns

A few system shortcuts rarely get used on purpose, so people bind other things to them and get confused when the system reacts:

• ⌘⌥D: turn Dock hiding on or off
• ⌘⌥Space: open a Finder search window
• ⌃⌘Q: lock the screen, which is a bad surprise when it was meant for something else
• ⌘⇧/: search the Help menu, in every app

Fix: check Keyboard Shortcuts → Launchpad & Dock and Spotlight, and untick anything you don’t use. That frees the combo properly.

Finding the conflicts that aren’t on this list

These ten are the common ones. Your Mac probably has others that only exist because of your particular apps: a window manager and a screen recorder both on ⌃⌥R, or a Karabiner rule shadowing an Xcode binding.

You can’t find those by reading lists. You need an inventory of every shortcut that’s actually registered on your machine. That’s what HotkeyClash is for: one scan reads every running app’s menu shortcuts through the Accessibility API, your Karabiner-Elements and skhd configs, and macOS system shortcuts, and then groups every combination claimed more than once. On a real working machine it found 736 shortcuts and 114 collisions in about three seconds.
