I am using an old Macbook Pro (13 inch, Mid 2014) with Version 10.11.6 of the OS. The OS can’t be updated anymore.
For the most part, the computer is still very functional with two caveats. I’m guessing and hoping these two caveats are related (and can be solved by the same solution)
First, I cannot visit any .dev domains whatsoever.trying to visit a .dev domain name There must be something unique about .dev domains that is stopping me from visiting them.
Second, when I visit non .dev domains, I get a "your connection is not private warning" trying to visit math.stackexchange.com
Keeping in mind that I cannot update my OS, is there anything I can do about this problem?
