How to Turn Off Autocorrect on Mac (and a Smarter Alternative)

Mac autocorrect is great until it changes a name to a random word or "fixes" something that was already right. Here's how to turn off autocorrect on a Mac — and a smarter way to fix your writing on your own terms instead.

How to turn off autocorrect on Mac

1. Open System Settings → Keyboard.
2. Click Edit… next to Input Sources (or open the Text tab on older macOS).
3. Turn off Correct spelling automatically, and optionally Capitalize words automatically and Add period with double-space.

That stops macOS from silently rewriting what you type. The trade-off: now nothing helps with spelling or grammar unless you ask for it.

A better trade-off: fix text on demand

Instead of letting autocorrect guess in real time, WunderType lets you fix text only when you decide. Turn off the intrusive autocorrect, write freely, then select your text and press a shortcut to clean it up — spelling, grammar, and phrasing — in any app.

Because it runs on a Custom Prompt you control (and on OpenAI or a local model), it never changes things behind your back. You stay in charge of every edit.

Best of both worlds

Disable the autocorrect that fights you, keep the help that you actually want, and apply it everywhere — Mail, Slack, Pages, the browser — with one keystroke.

Download WunderType from the Mac App Store and replace pushy autocorrect with corrections you trigger yourself.
