I need to convert an MKV video file to MP4, is there any solution for MacOS to do this? I appreciate any help

HandBrake allows users to easily convert video files into a wide variety of different formats.

Adapter is freeware (100% free software). Unlike other free apps, Adapter is lightweight and comes with a completely spam free installer that doesn't install toolbars or gunk up your computer. Adapter won't add obnoxious watermarks to your output.
