Hi, i can't open to my attachments on mac "snow leopard", is it because the OS is too old?
I can do it on my samsung s5(Android) and my macbookPro on "mavericks"
Yes, snow leopard is too old.
You need to run up-to-date browsers in order to run Tutanta. Unfortunately there is neither a current Safari, nor Chrome, nor Firefox for snow leopard.
