2. Update macOS and Video Players
If the macOS version running on your system has been outdated, then it can cause lag in its processing. That is why it is recommended to keep the firmware up to date to avoid any video lags.
Steps
Step 1. To update your Mac, just go to Finder and click on the About Mac option.
Step 2. Then, you can just click on the Software Update button to proceed.
Step 3. Finally, you can click on the "Update Now" button and maintain a stable internet connection to upgrade your macOS version.
3. Fix Slow VLC Player Lagging Problems
Why is video lagging on my mac? For this question, there is a useful repair tool called VLC. Despite being one of the most widely used media players, VLC occasionally has delays when playing videos. You can try putting the following suggestions into practice to resolve the VLC player lagging and resize videos.
Fix 1: Update Your VLC Player
To check for updates, simply run VLC Player and navigate to the Help menu. By doing this, the media player will automatically Check for Updates and allow you to finish installing them.
Fix 2: Skip the Loop Filter for H.246 Decoding
The VLC player's built-in H.246 decoding function is very useful for applying filters to decode certain footage. However, it may also result in laptop video latency. You may just navigate to Tools > Preferences > Advanced Preferences to resolve this. Simply choose the All option under the Skip the loop filter for H.246 decoding, then save your modifications.
4. Check Your Network or Browser
Fix 1: Reset Your Router
However, if you believe that there is a network issue causing video lagging on Mac, your router may be to blame. You may simply fix this by resetting your router. Simply press and hold the reset button, which is found on the router's bottom or back, for at least ten seconds. Following that, give it some time, reset your router, and then reconnect to your network.
Fix 2: Delete the Browser Data
Browser cache in programs like Safari, Chrome, and Firefox is another factor contributing to online video latency. All programs use essentially the same technique to delete their browsing data, including cache, cookies, and temporary files. Here are their procedures:
• Safari: Safari > Clear History > "All history."
• Chrome: Settings > Privacy > Clear browsing data (cached images/files).
Tips to Prevent Video Lagging on MAC
It's necessary to take precautions against video latency reoccurring even after it has been resolved. Many playback problems are caused by routine behaviors, such as downloading media from dubious sources, skipping updates, or keeping too many programs open. Over time, you may keep your Mac in good condition and experience more fluid performance by adhering to a few easy routines listed below.
• Free up storage: Maintain 15-20% free disk space (use CleanMyMac or Vidhex’s cleanup module).
• Use efficient codecs: Convert videos to H.265 via HandBrake or Vidhex (lower bitrate = smoother playback)
• Upgrade hardware: Regularly update macOS, browsers, and media players. Avoid running too many apps while streaming or editing videos.
• Enable "Automatic graphics switching": System Settings > Battery > Options > "Automatic graphics switching" (saves GPU resources).
By applying these preventive measures, you reduce the chances of video lagging on Mac and extend the lifespan of your Mac. In short, a little maintenance goes a long way—making your daily video viewing seamless, whether you’re streaming online, editing footage, or enjoying personal clips.
