Can't Play Videos on macOS 10.11 El Capitan After Upgrading

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.

UniConverter is my personal favorite when it comes to converting videos. What makes it great is how easy it makes the whole process. You can be an absolute beginner and still use it effortlessly. 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.
