How To Change the Default Video Player in Mac: Your Ultimate Guide
Want to watch your videos in your favorite player instead of QuickTime? This guide shows you how to change the default video player in Mac, ensuring your preferred application opens your video files every time.
Understanding Default Application Behavior on macOS
macOS, known for its user-friendly interface, uses a system of default applications to open specific file types. When you double-click a video file (like an .mp4 or .mov), macOS automatically launches the designated default video player. QuickTime Player often comes pre-set, but you have the power to customize this to your preferred application, such as VLC, IINA, or others. The benefit of changing the default application is consistency and efficiency. Imagine always having your videos open in the player you like, with your chosen settings, every single time.
The Benefits of Customizing Your Default Video Player
- Preferred Features: Different video players offer unique features. VLC, for example, boasts broad codec support, meaning it can play almost any video format without needing extra software. IINA is praised for its modern interface and macOS integration.
- Customizable Playback Settings: Perhaps you prefer specific keyboard shortcuts or have custom subtitle settings. Using your preferred video player as the default ensures those settings are always in effect.
- Streamlined Workflow: Eliminating the need to manually select an application each time you open a video file saves time and reduces frustration.
- Better Compatibility: Some players handle specific video codecs or formats better than others. Switching the default can resolve playback issues.
Step-by-Step Guide: Changing the Default Video Player
Here’s how to change the default video player in Mac using a few methods:
Method 1: Change for a Specific Video Type
- Locate a video file of the type you want to change (e.g., an .mp4 file).
- Right-click (or Control-click) on the file.
- Select “Get Info” from the context menu.
- In the “Get Info” window, find the “Open with:” section.
- Click the dropdown menu next to “Open with:” and choose your preferred video player from the list. If it’s not listed, select “Other…” and navigate to the application in your “Applications” folder.
- Click the “Change All…” button below the dropdown menu.
- Confirm your choice by clicking “Continue” in the dialog box that appears. This will apply the new default to all files of that type.
Method 2: Using “Open With” Menu (Temporary)
This method temporarily opens a file with a different application, without changing the default.
- Right-click (or Control-click) on the video file.
- Select “Open With” from the context menu.
- Choose your desired video player from the submenu. This only opens the selected file with that player. To make this a permanent change, follow Method 1.
Method 3: Using RCDefaultApp (Advanced)
RCDefaultApp is a System Preferences pane that allows you to manage file associations more granularly. Note that this method might require you to install third-party software. Proceed with caution and only download from trusted sources. RCDefaultApp can be helpful if Method 1 doesn’t work or you want to manage URL schemes and other file types beyond just videos.
Common Mistakes to Avoid
- Forgetting to Click “Change All…”: This is the most common mistake. Simply changing the “Open with:” setting only affects the selected file, not all files of the same type.
- Choosing the Wrong File Type: Make sure you’re changing the default for the correct video file type (.mp4, .mov, .avi, etc.). Different file types require separate changes.
- Using Corrupted or Outdated Video Players: Ensure your preferred video player is up-to-date and functioning correctly to avoid playback issues.
- Ignoring File Permissions: In rare cases, file permission issues can prevent you from changing the default application. Ensure you have the necessary permissions to modify the file.
Choosing the Right Video Player: A Comparison
| Feature | QuickTime Player | VLC Media Player | IINA |
|---|---|---|---|
| Codec Support | Limited | Extensive | Extensive |
| Interface | Simple, Mac-like | Functional, customizable | Modern, clean |
| Customization | Limited | High | Medium |
| macOS Integration | Good | Fair | Excellent |
| Best For | Basic playback, Apple ecosystem | Universal playback, versatility | Modern UI, macOS specific features |
Note: Codec support refers to the ability to play various video file formats. VLC and IINA generally support more formats than QuickTime Player.
Troubleshooting Issues
- Default Not Changing: Double-check that you clicked “Change All…” and confirmed the change. Restart Finder or your Mac.
- Video Plays in the Wrong Player Initially: Occasionally, macOS might cache the old default. Restarting your computer usually resolves this issue.
- Application Not Listed: If your desired video player is not listed in the “Open with:” menu, ensure it’s installed correctly in your “Applications” folder. You can then select “Other…” and navigate to the application.
Frequently Asked Questions
How do I change the default video player back to QuickTime Player?
You can revert to QuickTime Player by following the same steps as changing to a different player. Simply right-click a video file, select “Get Info,” and choose “QuickTime Player” from the “Open with:” dropdown menu. Then, click “Change All…”
Can I set different default video players for different file types?
Yes, absolutely. You can set different default players for different video file extensions (e.g., VLC for .MKV and IINA for .MP4) by following the “Get Info” method for each file type separately.
What happens if I uninstall the default video player?
If you uninstall your default video player, macOS will automatically revert to another compatible player. If no other compatible player is installed, it may prompt you to install one or display an error.
How do I clear the application launch services cache in macOS?
Clearing the launch services cache can sometimes fix problems with default applications. You can do this through the Terminal using the command /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user. Use caution when using Terminal commands.
Why is the “Change All…” button grayed out?
The “Change All…” button may be grayed out if you don’t have the necessary permissions to modify the file association. Ensure you are logged in with an administrator account.
Is it possible to set a default video player in the Terminal?
Yes, it is possible, but not recommended for casual users. Modifying the Launch Services database directly through the Terminal requires advanced knowledge and carries the risk of system instability if done incorrectly. It’s generally best to use the GUI methods.
Will changing the default video player affect audio files?
No, changing the default video player will not affect audio files. Audio files have their own default applications, which are configured separately.
What if my video player doesn’t support a particular video format?
If your default video player doesn’t support a particular video format, you will either see an error message or the video will fail to play. In this case, you can either convert the video to a compatible format or use a player that supports the format (like VLC).
Does changing the default video player affect online streaming services?
No, changing the default video player will not affect how videos play in online streaming services like YouTube or Netflix. These services typically use their own embedded players.
How do I prevent a specific video file from opening in the default player?
You can temporarily override the default player for a single video file by right-clicking it and selecting “Open With” then choosing the desired player. This won’t change the global default setting.
Can I use a video editor as my default video player?
While technically possible, it’s not recommended to set a video editor as your default video player. Video editors are designed for editing, not general playback, and may be resource-intensive.
What happens if I have multiple versions of the same video player installed?
macOS usually defaults to the most recently installed version of the application. If you have multiple versions and are experiencing issues, try uninstalling the older versions or manually selecting the desired version from the “Open with:” menu. Understanding how to change the default video player in Mac gives you control over your viewing experience.
