Turn Off Auto Correct in Mac OS X Lion

Annoyed with OS X Lion‘s new auto correct feature? You can turn disable it quickly:
- Launch System Preferences, click on “Language & Text”
- Click on the “Text” tab and uncheck the box next to “correct spelling automatically”
Auto correct in Lion is seemingly a lot more intelligent than past iOS versions, but it still can be frustrating when you are typing unique names of people, products, companies, slang, and even various tech terms.
Obviously if you want it enabled again, you just need to recheck that box.
Update: If you are experiencing annoying autocorrections like ‘colour’ to ‘color’ this is a language priority setting that must be adjusted separately in OS X Lion.

I like the spelling corrections and I haven’t found it to be a nuisance in Lion. I completely agree about iOS’s version though, it is overly aggressive and replaces words with other words, despite being spelled properly.
- and, of course, the auto-correct feature is annoying to people trying to type words -or entire documents, even- in a language other than english.
Exactly.
or Code.
Haha AMEN to that! Coding in Lion is hell with auto-correct.
Holy crap, is it being enabled in IDEs? Thats just…… bad.
intellisense type tools are more than capable of that without some stupid spelling checker converting “writeln” to “written”.
I didn’t had any trouble with Xcode, but yes with foreign english typing and other text like ‘waterlog’ becomes ‘waterloo’
i have unchecked it and its still auto correcting me even on msn! please help! x
same here… first i tried turning the feature off within the TextEdit application, but it didn’t work.. then read this thread and turned it off at the OS level, and STILL didn’t work, autocorrect is still on…
naughty naughty
Said in my best Irish/English accent, “have you tried turning it off and on again?”
I found it! Edit > Spelling!
After disabling from System Preferences, it shows as the blue bubble while typing, need to press the Esc before Space. I think that’s the max you can get for your money
seriously… thank you. I am so sick of typing things twice. I spend all day coding and using business names… they love to change them on me.
Mine is still auto correcting too. Lion is a huge PITA so far
I really like some aspects of lion. But 60% of its new “features” I’ve had to disable. Apple really need to abandon the stupid “no focus groups ” idea.
Ah, safari has it’s own. Edit > Spelling and Grammar, there it is
THANK YOU
[...] you disabled spelling auto-correct in Mac OS X Lion but find yourself still being autocorrected as you type various words in Safari, [...]
[...] autocorrect feature is very useful, so instead of turning it off, set a language priority and you’ll alleviate the aforementioned [...]
Thank you! It’s been bugging the hell out of me every day, I know the word is spelled right but it corrects it to something else anyway. Particularly bad when talking about Dragonball Z character names and music producing gear like the Maschine (corrects it to Machine)
[...] I was typing in OmniOutliner and I realized that OSX was trying to correct my spelling. It reminded me too much of using a mobile phone because it wasn’t my spelling that was off — it was picking on names. Best way is to turn off auto correct for spelling. [...]
Thanks…. it put an o in calling somebody a count and I realised it had to go!
For some reason when I go into my system preferences and click on the Text and Language tab there is no option to uncheck correct spelling automatically like shown in the picture. My computer still continues to autocorrect but I cant de-activate it because I don’t have that box.
What is really insane is when it “corrects” passwords. The damn things are supposed to be unique so correction virtually never makes sense.
