When calling SecKeyIsAlgorithmSupported (https://developer.apple.com/documentation/security/1644057-seckeyisalgorithmsupported?language=objc) with private key from secure enclave and parameters for algorithms and operations commonly not used for private keys causes crash on macOS. Same call with same parameters work on iOS.
I'm unit testing a utility with private key stored in secure enclave. When I call SecKeyIsAlgorithmSupported(:::) as below causes crash on macOS but not on iOS
SecKeyIsAlgorithmSupported(self.eccPrivateKey, kSecKeyOperationTypeVerify, kSecKeyAlgorithmECDSASignatureDigestX962SHA256); //where self.eccPrivateKey is key in secure enclave on my mac book pro.
Also crashes for these parameters :
SecKeyIsAlgorithmSupported(self.eccPrivateKey, kSecKeyOperationTypeEncrypt, kSecKeyAlgorithmECIESEncryptionCofactorX963SHA256AESGCM);
Crash

The same calls do not crash on iOS and correctly return NO
