IINA is a feature-rich utility that enables you to watch your favorite movies and play your music files from one place. This program is compatible with a wide variety of media formats, enables you to create and save playlists, and gives you access to various playback options.
It comes as an alternative to using Mac's QuickTime for playing videos on your computer. Unlike Apple's player, this tool supports much more video formats and provides you with a great experience, without dealing with constant frame freezes. In addition, you can attach subtitles to your movies and customize the playback settings according to your needs.
You can also use this utility to listen to your favorite music. Import the audio files you wish to play and save the resulting playlist for later.
Another useful advantage is the fact that you can use various shortcut keys to immediately complete tasks in IINA. They are listed in Preferences -> Key Bindings and can be altered if needed.
My only problem with this program is that you need to update if you want to get access to its latest version. However, completing this task won't take too long, a maximum of 2 minutes.
To conclude, IINA proves to be a reliable solution for playing videos and songs on your Mac. It's very simple to handle, brings you many useful features, and is free.
