Can we expect most of the safari freezing issues resolved after the Big Sur update? [closed]
Solution 1:
The first thing to do is work out whether this is a known problem with the OS that's affecting all or a significant group of users, or a problem that is specific to your computer.
I have found this report, which details problems with video freezing:
https://mrmacintosh.com/2020-002-update-causes-some-macs-to-freeze-when-using-hw-accelerated-video/
though this suggests that the latest Mojave and Catalina updates should fix it.
There should be one more update to Catalina before the release of Big Sur. Brand new OS releases may fix old bugs, but they often bring new ones too, so you may have to choose between which bugs you want to keep. ;-)
If it's a problem specific to your computer, rather than a bug in the OS itself, then a new OS may have no effect at all, and you need to identify the cause of the problem by looking a crash logs, and testing in a new user account or in Safe boot mode.
You may want to try using a different web browser, though that may not help if it is a bug in the OS.
