Somehow my normal computer, a MacBook pro, won’t open the site. It is very strange. It appears like there is no internet connection or something, but it is only for this site. Any ideas?
You might want to provide some details like: version of OS X, version of Safari, what AV or security software you are using. Safari has a Developer menu not available unless you can turn it on that might provide some details; If you don’t see the Develop menu in the menu bar, choose Safari > Preferences, click Advanced, then select “Show Develop menu in menu bar.”
P.S.: Do you have any other browsers to use? Here’s an article I found when dealing with this problem Best web browser for Mac: Safari, Edge, Chrome, Firefox and more | Macworld I had Opera, Vivaldi and Firefox installed; decided to give Chrome a try. (just set it up to keep google out of your business.)
