Resource:How to play Windows Media Video (WMV) on Mac OS X

It is possible to play Windows Media Video files (also known as wmv files) on a Mac. OS X does not come with any software that can play wmv files, but there is software you can download to get the job done. Three of the most common choices for playing wmv videos on a Mac are: Windows Media Player for Mac, Flip4Mac, and VLC.

Windows Media Player for Mac

Windows Media Player is available for Apple Macintosh computers. Microsoft no longer maintains or supports their WMP for Mac software, but they still provide it for you to download. You can download the software at Microsoft's website.
When you go to the Windows Media Player 9 for Mac download page, you'll be given a choice between a .bin file and a .hqx file. If you have an older Mac, you should download the .hqx file. If you don't, then it doesn't really matter. Just make sure you get the English version.


System Requirements
1. Mac OS X 10.1.5 or later
2. Mac OS X 10.2 or later recommended
3. 450MHz PowerPC G3 processor or higher recommended
4. Microsoft Internet Explorer 5.1 for Mac, America Online for Mac OS X, Netscape 7.1, MSN for Mac OS X version 2.0, or Apple Safari 1.0

Flip4Mac

Since Microsoft has stopped supporting Windows Media Player for Mac, they have made the Flip4Mac program available in its wake. Flip4Mac is a program offered by Microsoft and Telestream that gives Quicktime the power to play WMV videos. You can download Flip4Mac from Microsoft's website.
With Flip4Mac WMV installed, Windows Media files are associated with QuickTime. Opening a Windows　Media file from the Finder should automatically launch the QuickTime Player application. You can determine if　the file association is correct by examining the file icon:

A Windows Media file that is properly associated will display a QuickTime document similar tothe one shown here.
A Windows Media file that displays this type of icon is not associated with QuickTime. Opening　this file will launch Microsoft Windows Media Player 9 for Mac OS X.

To re-associate a Windows Media file with QuickTime Player:

1. Hold down the control key and click the file icon to display the shortcut menu.
2. Choose Open with > WMV Player.
The WMV Player application changes the file association and then opens the file with QuickTime Player. For　convenience you can add the WMV Player application to your dock. Then, to re-associate a Windows Media　file simply drag and drop it onto the WMV Player icon.

One caveat of Flip4Mac is that it cannot play WMV video that uses Windows Media digital rights management, so some videos may not be viewable even though you've installed Flip4Mac

VLC media player

VLC is a media player like QuickTime and Windows Media Player. Many view VLC is a good alternative to the these traditional media players because VLC is available for many different operating systems and is an open source software project that is supported by many dedicated programmers across the world.
Until recently, only experimental versions of VLC for Mac OS X could play WMV videos, but no longer. VLC for Mac OS X now supports WMV video. You can download VLC from the VLC media player for Mac OS X download page.

There are three types of downloads on this page: “Universal Binary”, “Intel Package”, and “PowerPC Package”. The Universal Binary should work on any Mac, the Intel Package is meant for newer Intel-powered Macs, and the PowerPC Package is meant for older Macs that use the PowerPC processor. If you are unsure of whether you've got an Intel Mac or a PowerPC Mac, use the Universal Binary Package.
Once downloaded, double click on the dmg file, wait for a Finder window to open, and then drag the VLC icon to your “Applications” folder.


In addition, VLC media Player supports audio and video formats (MPEG-1, MPEG-2, MPEG-4, DivX, mp3, ogg, ...) as well as DVDs, VCDs, and various streaming protocols.
