Keyboard Shortcut to Switch Input Language on Mac

If you type in two languages, the switching shortcut gets pressed hundreds of times a week — it's worth choosing deliberately. macOS gives you three built-in options: a Control-Space chord, a single tap of the Globe key, or Caps Lock doing something useful for once. All three work in macOS 13 Ventura through 15 Sequoia; here's how to set each up and which suits which typist.

The default: Ctrl+Space and Ctrl+Option+Space

Out of the box, once you have two or more input sources, Ctrl+Space flips to your previous input source and Ctrl+Option+Space cycles through all of them in order. The distinction matters: with exactly two languages the two shortcuts feel identical, but with three or more, Ctrl+Space keeps bouncing between the last pair you used while the longer chord walks the full list. Hold the shortcut rather than tapping it and a small switcher panel appears so you can see where you're landing.

Both are reassignable: System Settings → Keyboard → Keyboard Shortcuts → Input Sources, double-click the current combination, press a new one. The undo is the Restore Defaults button in the same pane. Reassigning is worth considering because Ctrl+Space is contested territory — IDEs and some launcher apps claim it for autocomplete or search, and whichever registered first wins confusingly.

The Globe key: one tap, no chord

1. Open System Settings → Keyboard.
2. Set Press 🌐 key to to Change Input Source.

Now a single tap of the bottom-left key cycles your layouts. It's the lowest-effort option and the easiest to explain to someone else, with two caveats: it's only offered on keyboards that have a Globe key (Apple silicon MacBooks, recent Magic Keyboards), and it repurposes a tap you might prefer for emoji or dictation. Undo by setting the menu back to Show Emoji & Symbols, the default.

Caps Lock: the sleeper option

1. Open System Settings → Keyboard and click Edit… next to Input Sources.
2. Turn on Use the Caps Lock key to switch to and from ABC.

This checkbox appears when your sources include a non-Latin input method alongside ABC — think Chinese, Japanese, Korean, Hebrew, Russian setups — and it turns Caps Lock into a dedicated one-tap language flip. You lose nothing: holding Caps Lock briefly still toggles capitals, while a quick tap switches input. For bilingual typists whose second script isn't Latin, this is often the fastest of the three, because it's a single large key hit by the little finger without any chord. Uncheck the box to undo.

Which one to pick

• Two Latin-script languages, heavy typist: keep Ctrl+Space — bounce behaviour is exactly right.
• Non-Latin second script: the Caps Lock toggle, hands down.
• Casual switching, recent MacBook: the Globe key tap, because you'll never forget it.

Whichever you choose, keep the Input menu visible in the menu bar while you settle in — the icon confirms at a glance which layout is live before you type a sentence in the wrong one.

A final habit worth building: whichever trigger you settle on, stick to it exclusively for a week. Mixing three switching methods is how you end up mid-email in the wrong alphabet with no muscle memory telling you why. And if switching feels like it happens too often to be worth any shortcut, look at Automatically switch to a document's input source in the Input Sources Edit sheet — it makes macOS remember the layout per document, so most of your switches happen without a keystroke at all. The shortcut then becomes the exception, used only when starting something new in the other language — a much smaller job for whichever key you gave it.
