Wikipedia can definitely be considered one of the most useful sites we use. However, Wikipedia doesn’t have to be accessed through a web browser – you can use Apple’s Dictionary to browse through Wikipedia articles. Just a few simple steps are required in Dictionary. Here’s how you do it.

1. Open Dictionary.app and go to Preferences

2. In Preferences there is a list of sources. Scroll to the bottom of the list and select Wikipedia, then exit Preferences

Now a Wikipedia tab should be visible, next to the Dictionary and Thesaurus Tabs (If thesaurus is an active source in your dictionary).

3. Simply search in the search bar and the result we be from Wikipedia.
