I am on a 2017 MacBook Air, Intel i3, 8GB RAM, I am on Big Sur 11.5.1 and every video, including the video previews for trackpad gestures are stuttering. I have done virus scans with Malwarebytes and it found nothing. YouTube and downloaded content is slow, please help.

Try using Activity Monitor to check if there's something using an excessive amount of your CPU:
- Open
Activity Monitor.app
. You can find it via Spotlight or in/System/Applications/Utilities
. - At the top of the window, click the
CPU
tab. - In the menu bar, click
View > All Processes
. - Click on the
% CPU
column header to order the list by current CPU usage.
If a specific app is using a lot of CPU (around 100% or more), try quitting it. If it doesn't respond, try force quitting by selecting it in the list and clicking the Stop
button in the toolbar.
