Hi. Running 10.7.5 on an '09 Mac Pro and I have been having problems with GMail for Business, which Google support thinks are specific to my Macs. I access three mail accounts from my browsers, two GMail for business and one personal GMail, often switching between them from GMail. What happens is that when I initially go to GMail and try to log in to an account, I more often than not (almost always) get a "that page is currently unavailable" message and an "SSL error" message usually follows after clicking the "more" button in the message box. Sometimes the loading just halts and the message comes after I repeatedly try to refresh. The problem occurs in all my browsers (Safari, Chrome, Firefox- all latest versions). It does not seem to happen with ios devices running latest versions of Safari and Gmail client. The problem is most pronounced with Chrome, ironically, and Safari, Firefox are much better but still a pita. GMail support is usually very good and my agent this time was no exception, yet told me "it's your computer" (both of them, plus Macbooks?). Does anyone have a similar experience or an idea as to what's happening here? Thanks in advance for any clues. PS- I should mention that it happens at home (isp Verizon FIOS) and at office (Optimum broadband), on two very similar Mac Pros running same software. Each LAN basically configured by installers in a very straightforward way. Problem is not new but first manifested fairly recently. The only change is my usage habits; I now have taken to switching accounts from GMail button. I have tried clearing browser caches.
