- title Switching to Ubuntu from Mac OS X
This provides information, resources and terminology to help you switch from OS X to Ubuntu. See also the all-systems switching guide. OS X is an Apple interface wrapped around a Unix core, whereas Ubuntu is a Unix interface wrapped around a Unix core. This makes switching from OS X much easier than switching from Windows, but still quite challenging. For example, the OS X terminal is almost as powerful as the Linux terminal, but you'll need to use far more of that power in Linux.
The most obvious difference between OS X and Ubuntu is when installing software. In OS X, you usually buy or download programs in `.dmg` files. The Ubuntu equivalent of a `.dmg` file is a `.deb` file, although you'll rarely see one in practice. Ubuntu has a built-in package management system, and it's recommended to install programs from there. See the install software guide for more information. Programs installed through Ubuntu are guaranteed to work with Ubuntu, and automatically updated when you upgrade to the newest version of Ubuntu. In the same way that OS X only runs software designed for OS X, applications must be made for Linux to be able to run on Ubuntu. Most Linux software is available for free over the Internet. The following pages feature a small selection of popular applications available for free in Ubuntu: Linux|equivalents for popular Mac OS X software <<Include(../PopularPrograms)>>
Linux includes a terminal, very similar to the terminal in OS X. Many Linux guides ask you to run commands in the terminal, which should be available from Applications > Accessories > Terminal. See Using the Terminal for more information.
