There are several factors that can cause videos on your Mac to lag, and understanding these causes can help you troubleshoot the issue and get back to enjoying your videos.

One of the most common reasons for slow or lagging videos on your Mac is due to insufficient bandwidth. If you are connected to the via Wi-Fi, it is possible that there is too much traffic on the network which is resulting in lower speeds and buffering. If this is the case, try connecting via Ethernet for a more reliable connection. Additionally, if you are using an older modem or router, it may be time to upgrade for a faster connection.

Another factor that can cause lagging video playback on your Mac is related to the files themselves.

In this case, try downloading the video again from a different source if possible.

It's also important to keep track of cache and temporary files as they can accumulate over time and take up storage space on your system which could be slowing down performance in general including video playback speeds. To clear out any unnecessary files, open Finder and select “Go” > “Go To Folder” then type in ~/Library/Caches/. From here delete any files that are not necessary for the proper functioning of your system such as old web pages etc..

Finally, updating graphics card drivers may also help with lagging videos as outdated drivers can contribute to slower performance when playing certain types of media content. To check for driver updates visit Apple's website at https://support.apple.com/drivers .

If all else fails, converting videos into different formats such as MP4 or AVI using third-party like Handbrake may also help with video playback issues as some formats may not be compatible with certain operating systems or hardware configurations on your system.

By following some of the above tips you should be able to get back up and running smoothly without too much trouble so that you can enjoy watching and shows online without experiencing any lag or buffering!
