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.
