anti-alias disabled

You probably know by now that you can zoom into anything in Mac OS X by holding down the Control key and then using the scroll wheel or a two-fingered forward swipe on the trackpad. You’ve also probably noticed that the more you zoom in, the blurrier things get because you’re zooming into anti-aliased graphics and text.

Toggle & Disable Anti-Aliasing in Mac OS X Zoom

You can disable and toggle the anti-aliasing within the Mac OS X Zoom feature by hitting Command+Option+\ after the zoom feature is activated. In other words, Control+Scroll to zoom, and then hit Command+Option+\ to toggle anti-aliasing.

Here’s before and after pictures of what text looks toggling the anti-aliasing:

And after, the text is much more crisp:

This effects all on-screen graphics, not just text.

    Sorry but I can’t do it. When I zoom I press “Command+Alt+the key just below esc” and nothing happens, am I doing anything incorrect? Maybe it’s because I am using a spanish keybord

    Thanks for the tip.

    @all those who have no us keyboard layout: You need to compare the us keyboard layout to your own to find the “\” key.
    E.g. on German keyboard layout the “\” key does not exist since you need to press option + shift + 7 to get the “\” character.
    So i need to press command + option + # (because “#” in German layout is located there where the “\” key is in us layout).
    Hope that helps.

    Kind regards.
