Good Morning,
I have recently been loaned a 2011 Macbook Pro from a family member. The laptop had not been used in several years. The OS was Sierra. Dropbox was installed but didn't work. I got a message that the minimum OS requirement is High Sierra. I upgraded to High Sierra. Dropbox still does not work because the browsers are too old (Google, Safari, Firefox) and cannot be upgraded to to the OS version.
I can have access if I go through Yahoo but prefer to go directly from Dropbox, Google or Apple. What is the best solution?
