Safari Playing YouTube videos & more too fast

Hello, this happens very sporadically. I thought it had been resolved with the last update but it just happened again. Before, I had been fixing it by going into Activity Monitor and stopping the coreaudiod file & restarting Safari, but since this last update, that file doesn't show up in the activity monitor anymore. I have no extensions in Safari anymore because I saw that in another post about this same thing.


Today it happened after I tried to scroll back a little in the video, that tends to be when it happens, although at one point, it kept happening a lot so I switched to Firefox. After this last update, I went back to Safari and everything seemed ok.


Thank you!

What happens when you test in a different browser (?)


To trouble shoot further you can:


Try a SafeBoot https://support.apple.com/en-us/HT201262

Takes noticeable longer to get to the login screen, does a 5-15 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc. Login and test. Reboot and test as caches get rebuilt.

This test will tell you if third party interference; extensions etc are not loaded in safe boot mode.


Test issue in another user (or guest user) account  https://support.apple.com/en-us/HT204443

This will tell you if it a universal issue or isolated to your user/admin account.
