Although my Mac mini (Mid 2011) running macOS High Sierra 10.13.6 (can’t upgrade) is pretty old, I have been keeping it “up-to-date” using Homebrew, where possible.
However, as of this week that fails due to SSL certificate issues:
curl: (60) SSL certificate problem: certificate has expired More details here: https://curl.haxx.se/docs/sslcerts.html
Might be related to the Let’s Encrypt root certificate expiring (yesterday/today)?
What can I do about this? (If anything?)
