I just updated to Catalina 10.15.8, and now Safari won't open any websites. I'm on a really old iMac 21.8 inch, late 2013. Could someone help me as I can't afford a new computer right now. Thank You.

Use Firefox instead of Safari. Firefox is still supported on Catalina; the current version is 147.0.3.


And while Firefox privacy & security is excellent, I suggest adding the Privacy Badger and uBlock Origin plugins after you install Firefox. Go to Firefox Browser Add-Ons and use the "Find" box to install them.


The version of Safari on Catalina is out of date by at least 3 generations.

Thank you MartinR. I downloaded Firefox and it appears to be working good! This Catalina 10.15.8 update has made other apps on my computer buggie too. My Apple Mail would not receive or display my emails from multiple accounts. A restart did not fix the problem, but a hard shut down and restart did fix both problems and now Safari and Apple Mail work OK. I am going to be leery in the future of doing these types of updates on really old Mac's.
