RAR is one of the most common formats for archiving or compressing multiple files into one, as it is able to archive entire folders while preserving their inner structure. Although Mac OS X operating systems come with the default "Archive Utility" installed, it will not open RAR files. Instead, Apple's suggests the free software called StuffIt Expander, which supports RAR and more than a dozen other formats. Once you decompress the audio in a RAR file, you can easily import and convert the tracks to MP3 in iTunes.

Opening RARs With StuffIt Expander

Step 1

Open your Web browser and visit Apple's download page for StuffIt Expander. Click the "Download" button in the upper-right corner of the screen to download the latest free version of StuffIt Expander and wait for download to finish.

Step 2

Double-click the StuffIt Expander DMG file to mount the program in Finder and begin the installation process. Follow the onscreen instructions to drag the StuffIt Expander icon to the "Applications" folder and agree to the terms of use to complete the installation.

Step 3

Navigate to the RAR file on the computer and right-click its icon. Hold the mouse pointer over the "Open With" arrow and select "StuffIt Expander" from the list of available programs. If StuffIt Expander does not show up in Finder, click "Other" at the bottom of the list and double-click "StuffIt Expander" in Applications. StuffIt Expander automatically opens the RAR file and display the audio files.

Importing and Converting to MP3 in iTunes

Step 1

Open iTunes. Go back into Finder and highlight the unarchived folder or individual audio files. Drag and drop their icons into the iTunes library and wait for them to copy.

Step 2

Click the "iTunes" button at the top of the screen and choose "Preferences."

Step 3

Press the "Import Settings" button in the lower-right corner of the General Preferences window. Click the "Import Using" drop-down box and select "MP3 Encoder." Press "OK" twice and exit back to the iTunes library.

Step 4

Locate the newly imported audio files and highlight their icons. Create new MP3 versions of the music (while retaining your files in their original format) by clicking "Advanced" and "Create MP3 Version." Convert your actual files -- replacing the audio with MP3 versions -- by clicking "Advanced," holding down "Option" on the keyboard and selecting "Convert to MP3."
