I've tried everything, but no matter what I try, video playback is incredibly laggy on every video playing website I know. YouTube, Netflix, even QuickTime player. At first, I thought it might've been a virus, and I tried an antivirus but it only made things worse. How do I fix this? It plays smoothly for a couple of seconds before it freezes, and then continues at 1 frame per 3 or 5 seconds before repeating
MacBook Air 13″, macOS 12.6
The only thing that my computer is slow with is video playback. Nothing else. I have quite a lot of available space on my Mac, and nothing I do seems to fix anything

Good afternoon The_Train_Enthusiast,
We'd like to help with the issue you are having with video playback on your MacBook Air. What is the model year for this computer? See > About This Mac. We ask, because updating the computer to macOS 13.4 would be one of the first troubleshooting steps to address this issue.
It sounds like you are asking about video when streaming, not playing back video files that are stored on your computer, is that right? If so, the next step would be to check the speed of your network. Are you using Wi-Fi or are you connected via an Ethernet cable to your modem/router? (A wired connection is much, much faster.) What is the download speed on your network?
Try quitting Safari and shutting down the computer.
Then, unplug the power to your modem/router (if a single unit), wait for a minute, and plug the modem and router back in. Wait till the status lights are green, and then turn on your Mac and open Safari. Check the network speed again and see if a previously opened website and video plays any better after "recycling the power" to the network.
Let us know the results and we'll go from there.
If Safari doesn't open a page or work as expected on your Mac
Take care.

Hi The_Train_Enthusiast,
Thanks for the followup. Next, we suggest booting your Mac into safe mode to see if the issue persists. You can find steps for doing so here: How to use safe mode on your Mac - Apple Support
Safe mode prevents your Mac from loading certain software as it starts up, including login items, system extensions not required by macOS, and fonts not installed by macOS. It also does a basic check of your startup disk, similar to using First Aid in Disk Utility. And it deletes some system caches, including font caches and the kernel cache, which are automatically created again as needed.
Safe mode is particularly useful when you're trying to resolve an issue that doesn't seem to be associated with using any particular app.
Let us know if that helps.
Take care.
I have a 2015 MacBook Air, so I'm not able to update to Ventura. And this problem is for my Mac only. Every other device works perfectly fine.
Reinstall Mac os backup with Time Machine
Good luck!
