HenryV Posted December 9, 2020 Share Posted December 9, 2020 If you are having trouble with Safari you might want to see if the technology preview version will overwrite the problem version. Even if it does not overwrite you could stop using the problem install. Link to comment Share on other sites More sharing options...
kushwavez Posted December 9, 2020 Share Posted December 9, 2020 (edited) Oh yes forgot to mention, trying Safari Technology Preview didn't solve the problem. Edited December 9, 2020 by kushwavez Link to comment Share on other sites More sharing options...
eSaF Posted December 9, 2020 Share Posted December 9, 2020 @kushwavez I suggest something else is going on with your system because this is what mine is reading. Down-grading to a previous version of Safari I don't think will help here. Spoiler 1 Link to comment Share on other sites More sharing options...
kushwavez Posted December 9, 2020 Share Posted December 9, 2020 (edited) It's only happening on 1080p streaming sites (usually high demanding ones for example HEVC FLAC videos) (except YouTube). Well, it's a bug with Big Sur because as I said it's happening on 5 system including real Macs too. It's not happening on Catalina. On Activity Monitor View settings enable "All processes" and watch kernel_task. Ways to reproduce: Open a 1080p streaming site (for ex. some series streamer sites or smth like that) and start a video. Pause it, go to another tab, then go back. Unpause it. Watch kernel_task goes all the way up Edited December 9, 2020 by kushwavez Link to comment Share on other sites More sharing options...

Watch kernel_task goes all the way up I tried to follow your instructions as best as I can to induce the kind of behavior by opening and playing a film on Netflix and took a screen shot to see if it is the same on mine - Have a look and see if I am missing something here or I didn't quite follow your directions. PS - I just came across this - https://developer.apple.com/forums/thread/663850 - someone posted about the same problem.

Watch kernel_task goes all the way up I tried to replicate this problem and found that I could replicate it but only on certain websites. The problem did not occur on YouTube or Netflix. Knowing what people often stream at 1080p, I checked other sites and streaming 1080p gobbled up my memory. It was worse streaming 2160p. Don't blame your system for the websites you choose to frequent. Perhaps another browser will serve you better. Otherwise, use Activity Monitor to decide which websites to avoid.

kushwavez Posted December 9, 2020 Share Posted December 9, 2020 Here, a pretty good example of the problem. Well, I have to use Chrome because of this, but I don't like it because then I can't use iCloud tabs, etc. If it'll not improve in later versions of Big Sur, then I'll going back to Catalina unfortunately. That's why I wondered if I could downgrade Safari to 13 or not. https://streamable.com/bkojg7 1 Link to comment Share on other sites More sharing options...
