Why I Can't Play Videos on macOS El Capitan after Upgrading?

The problem is that the OS is currently in beta, so Apple is still working on fixing the bugs. Until the final version is released later this year, issues like these are inevitably going to come up. Furthermore, when you try to play a file format that is incompatible for Mac, you’ll encounter codec issues. The easiest way to surpass this is to convert the files into a compatible format. You can do this through different programs.

It has many convenient options, including: downloading videos online, converting to other formats more quickly and without losing quality, using it as a video player, converting 2D to 3D, capturing screenshots, merging multiple videos together and many more.
