Get the Best MP4 Codec for Mac Alternative
If you have downloaded an MP4 file, but can't play it on your Mac with your regular player, it probably means that the player doesn't support the MP4 format. In order to play MP4 codec on Mac you can use one of the solutions described in this article.
1. Elmedia Player
Probably the best MP4 codec Mac player that supports this type of files out of the box. Elmedia Player supports a variety of codecs and doesn't require any additional installation of codec packs or any high maintenance.

2. Install Perian codec pack
There is an MP4 codec download for Mac - Perian is a universal codec resource for Apple computers that is somewhat similar to K-Lite Codec Pack for Windows computers. Perian supports AVI, MP4, DIVX, FLV, MKV, GVI, VP6, and VFW file types and can be used with QuickTime Player, NicePlayer, QTAmateur and other QuickTime supporting players.
Note: Unfortunately the latest and last version of Perian 1.2.3 doesn't work with 10.8 (Mountain Lion), 10.9 (Mavericks), 10.10 (Yosemite), 10.11 El Capitan, 10.12 Sierra.
3. Online video converter for Mac
