Kiwix is a Mac program that provides you with a solution when you need to access info from the Wikipedia website and you don't have an Internet connection. The application allows you to download libraries containing certain categories of information from Wikipedia and access them when you don't have access to the Internet or you're dealing with a low connection signal.
The main window of the program looks a lot like the Wikipedia page. So, if you're familiar with the aforementioned webpage, you'll definitely be able to handle this utility. Just type the keywords in the search panel and the application will give you access to the information you need within moments.
Another great thing is that some of the available libraries are distributed in a wide variety of languages.
In my testing, the utility worked perfectly. I immediately downloaded the content I needed and found the information I was looking for within the fetched Wikipedia library.
In conclusion, you should try this Mac program if you wish to have access to Wikipedia information when you don't have an Internet connection signal. What's more, you don't have to pay a buck to use it on your computer.
