How to Get an ISO From a RAR on a Mac
By Julius Vandersteen
If you have an ISO image on your Mac that has been archived using the RAR compression format, you need to use a utility to decompress the RAR file so you can use the ISO image. An ISO image is a file that is an exact copy of a CD-ROM or a DVD image -- if you mount an ISO image on your Mac's desktop, it functions as if it were an actual mounted disc. You can easily use a free utility to decompress an ISO image that has been compressed with the RAR format.
Download the free MacPAR Deluxe utility from the Gerald's Software website at xs4all.nl.
Double-click the MacPar Deluxe icon to launch the utility.
Click "Process" from the MacPar Deluxe menu, then click "UnRAR Archive." A dialog box opens. Click the folder on your Mac containing the RAR file of the ISO, click the RAR file to select it, then click "Open." MacPar Deluxe decompresses the RAR file to get the ISO image, which is in the same folder as the RAR file.

Click the folder on your Mac that has the RAR-compressed ISO image, click the RAR file to select it, then click "Expand." The ISO image appears in the same folder as the RAR file it is expanded from.
