This isn't really a FreeRADIUS question. You'll need to look in the OS logs to figure out why it's unhappy. Unless you've screwed up the certificate chain, or aren't sending the right certificates, there's probably nothing you can do on the FreeRADIUS side.

The mini-CA generated by FreeRADIUS does work out of the box, so if you're using that you've either broken the config, or the client is not working right.

Use 'openssl x509 -in cert.pem -noout -text' to compare the CA signed and your own certificate (and your root vs their root). Make sure you're using a sha256 hash, that the constraints are all correct, and the key usages are sensible. Make sure you've not set a path length shorter than your chain - things like that. 

Try removing all the certificates, rebooting and reconnecting. I've seen OS X get confused and try using credentials cached somewhere, but that have been removed from the keychain.
