the glitch.com site and all pages (eg: glitch.com/about) shows blank page and safari says:
“because Safari can’t establish a secure connection to the server”
iOS can’t be upgraded, this Mac Mini is part of a kiosk and quite old
You should really update your browser, thats probably why. I’m not sure that Safari supports the latest version of TLS.
or just refresh
the Chrome browser I mention is well above the lower limit
I did think of that, yes
A quick check shows that version of Chrome is 5 years old. Another mac user posted a question about another site and someone responded “Unfortunately, the version of Chrome you’re running is no longer supported by either Google or the website you’re using (by your description of the issue).”
I guess the question is, what are you hoping happens between now and when you upgrade your browser, your OS or both? It is a sad reality but a reality none the less.
