Mac OS X Lion features automatic spell correction out of the box. The way it works is similar to autocorrect in iOS. As you type, Lion notices a misspelled word and offers a correction. To accept it, just keep typing.
It sounds great, but in my experience it causes more errors that it prevents. Often times I’m several words ahead of the “correction,” and don’t see it land.
It’s a hassle, and I’ve turned it off. Here’s how.
- Open System Preferences
- Click Language and Text
- Click the Text tab
- De-select Correct spelling automatically
Now your mistakes will be your own, and not your Mac’s.
