VLC 0.8.1 fails to work on some versions of Mac OS
If you are a Mac user and can't install VLC 0.8.1 it is probably because your operating system is OS X 10.1.5, Mac OS 9, or lower than this.
VLC is not supported for these versions of the operating system and will never be.
If you have Mac OS X 10.1.5 or lower all you can do is update your system to Mac OS X 10.2 or newer which is faster than 10.1.5. When this is done you should be able to install VLC properly without any trouble.
