why my Macbook won't read other files like avi?

If you want to play avi movies on your MAC then try "DivX 7" player, in this way you can download movies which are in avi format.

i don't have mac, but i use vlc player for playing most of my avi files. if you want to try it, there's a mac version of vlc player... here: http://www.videolan.org/vlc/download-macosx.html

Oh that's a simple problem with a simple solution and they are free. You don't need a converter actually. Just like Zer0Stats said download Perian to play MS Windows video files in Mac OS Quicktime video player. Another one is downloading and installing the VLC player. Which is one of the most favorable video player of any kind of operating systems like MS Windows, Linux and Mac OS. It can also play Real video files (like .rm, .rmvb).

I think this is a codec issue. Have your tried checking with Apple Support already?

Try downloading VLC media player, it's free and can play any type of media extension such as .avi, .mkv, .flv etc......

by default MAC doesn't support AVI files but you can download codecs and other players like divx and VLC they can play AVI if they can't then it's time to download the codecs

you can get codecs so that you can play .avi file in macbook.. you can get it from http://www.thexlab.com/faqs/avidivx.html and http://guides.macrumors.com/Watch_AVI_Movies_in_Mac_OS_X you can download and install codec freely and also you can install vlc player with avi support in macbook..

I'm not a Mac PC user, although I have an iPad, and it also doesn't read files iin avi format. But it wouldn't hurt if you install a converter. I myself had installed a converter. Although my Pc can read mp4, a software that I use for work doesn't read them so I need to convert them to avi instead.

It has been my experance that, Mac has a flaw as it's vary particular on what it can and can't play. Have you had this issue before? Did it just start? Do you have this problem with other mac-based computers or tablets? If the answer is no, than there is a bug with your particular nacbook. If the answer is yes, then download the suggested software to play a wider ranger of files.

Hmmm download Perian.It is a free,open source,QuickTime component that supports many popular media types.

If you want to play avi movies on your MAC then try "DivX 7" player, in this way you can download movies which are in avi format.
