Why VLC Won’t Open on Mac

VLC is a lightweight media player that works well with most OS and other programs on the computer. However, there are times when conflicting apps are running, preventing VLC from loading properly. If this is the case, you need to single out which software is causing the conflict, though this might be challenging and time-consuming to do.

Another factor you have to investigate is the possible corruption of the app itself. If your VLC app or any of its system files has been corrupted, the app won’t be able to start correctly. The corruption might be caused by missing files or by malware.

You also need to check the version of the app you are running. This is particularly true if you encountered the error right after you have installed a system update or upgraded to another macOS version. A compatibility problem might occur between your operating system and the current version of the app you are using, resulting in the error.

Sometimes the reason behind this error is obvious, so you already have an idea how to troubleshoot the problem. But more often than not, the problem just pops up randomly, to the surprise of the user. This makes it difficult to determine the proper course of action.

How to Fix VLC Not Running on Mac

• Close the VLC app completely by using the force-quit menu (Apple menu > Force-Quit). Once VLC has completely stopped running, re-open the app to see if it is able to start properly now.
• Try opening other files. If you encounter the error while opening a particular file, it is possible that the file is corrupted so you need to try using other media files.
• Clean up your Mac using Outbyte MacRepair and delete all unnecessary files that might be stopping VLC from functioning properly.

6. Delete everything with VLC in its name, such as org.videolan.vlc.
7. Re-launch VLC and check if it can now launch properly.

Fix #2: Update VLC.

If you’ve recently upgraded to macOS Big Sur or other macOS version, you should also update your VLC player to make sure it works smoothly with the new OS. You can check the MAc App Store to see if there are any pending VLC updates you need to install or go to VLC’s website and download the latest update for your app. Once you have updated VLC, try to open it again to see if it works.

Fix #3: Reinstall VLC.

Your last option is to uninstall VLC and then install a fresh copy of the media player on your Mac. To uninstall, simply drag the VLC app icon from the Applications folder to the Trash. Don’t forget to delete all files associated with the app, including the preferences file and cached data. Once deleted, download the latest version of the VLC app from the website and install according to instructions.
