Xcode can't verify the identity of the server “github.com”, Xcode

Question

Sorry for the dumb question, but I\'ve been getting this on Xcode. I\'m not sure

Answer 1

None of the certificates in the CA chain for GitHub appears to have just expired or be closed to expire.

This article (on rail app, but also relevant here) suggests:

• install MacPorts
• use OpenSsl
• if have a directory /opt/local/etc/openssl:

$ cd /opt/local/etc/openssl
$ sudo curl -O http://curl.haxx.se/ca/cacert.pem
$ sudo mv cacert.pem cert.pem
$ setenv SSL_CERT_FILE /opt/local/etc/openssl/cacert.pem
