Codec Pack For Mac Os
1. It's known to all that Mac default video player QuickTime doesn't support AVI files, let alone AVI codec. To play AVI on Mac, you can download and install Perian codec pack for Mac, which is aimed to help you successfully play AVI files with the most common DivX and XviD codecs supported.

2. If you still received an error 'A Required Codec is not Available' on your QuickTime after installing Perian codec pack, the potential reason might be the AVI files with complex AVI codecs not only the common DivX, XviD but also MPEG, QPEG, etc. QT unsupported codecs. In such case, the better solution is to convert AVI to QuickTime MOV format. MacX Video Converter Pro might be the one you can count on.
