My need is to efficiently detects if OS supports secure enclave. There seems to be one way to decide if the Secure Enclave is present: Create an elliptic curve encryption key in the Secure Enclave, If this fails, and the error has a code of -4 = errSecUnimplemented, then there is no Secure Enclave.
My question, is there any way other approach to detect if system supports secure enclave?
