FOR THE LOVE OF GOD, fix your problem with MAC Excel's ability to open https hyperlinks!!!!
I swear if I read "cannot open the internet server or proxy server" ONE MORE TIME I WILL THROW THIS COMPUTER THROUGH THE WINDOW. The addresses have been verified by a third party certifier. I DON'T UNDERSTAND WHY SOMETHING SO SIMPLE CONTINUES TO BE A PROBLEM!!!

I feel your pain! This is so frustrating! Every time I open the sheet the same message is displayed. Very annoying that you cannot "do not show again" these type of alerts.
