Why does my iMac show blank screens when logging into certain sites?

If I try to log into a site, I'll hit the log in tab and it just brings up a white screen with nothing on it.

Also, on some sites that have pictures to describe what they offer won't come up. Just a blank spot where the picture is with a blue square.

The computer won't update anymore, I assume because of age.

Yep. Support for macOS Catalina has all but disappeared and the computer is living on borrowed time. Internet standards have changed and the old Safari browser cannot make the required secure connections.

You might try installing the Firefox browser. I understand that the current version still works in Catalina, for now.

Bad news or good news?


Using Safari 14.1.2, I think I get the same problem with this hardaddy site as you. There are some pictures shown but mostly not.


The good news is that even my version of Firefox (115.23.0esr) seems to work just fine so, if you haven’t already, as D.I Johnson advised get Firefox: search for “Firefox download for mac”.


For Catalina 10.15 you can get the latest version 138.0.1.
