Safari won’t load, it freezes shortly after I open it and the coloured wheel appears I have been having problems with the Safari on my MacBook Air (Retina, 13-inch, 2018) in the last couple of days. I updated it yesterday to Catalina 10.15.7 and I have Safari Version 14.0.
Now every time I open safari, I get to the favourites page and when I click on a website (like moodle, or websites from my school) it always freezes and the coloured wheel starts spinning and the fans start turning really loudly. I can’t close the browser, and I have to “quit” Safari, but that doesn’t work, so I have to “force quit” it. And when I restart Safari the same thing happens again, so I tried to force-restart my laptop, because Safari is frozen. But when I restart it the same thing happens again. And I just have 1 website/tab/window open, and it used to work fine in the past.
I closed all the other apps, and tried reopening Safari multiple times. And then I tried restarting my mac several times.
I tried to run diagnostics on my laptop and that said there were no problems.
I deleted all my Safari History and I emptied my Caches.
I do not have any extensions.
I usually can’t even log into my university-moodle-account, and when I can, I can’t download any of my homework or watch the video-recordings of the lectures.
I don’t know how to fix it.
I just had a Macbook Air with Safari that would immediately crash when trying to launch.  This was on a Mojave system.
To fix, I would up reinstalling OS (reboot and press and hold Command+R).
Safari is now working fine.
