&gt; Source? Current discussions surrounding your statement point to it being false - that Apple can update the firmware of the secure enclave without it wiping out it&#x27;s data.<p>Do you have the source for that, too?  I was still under the impression that the Secure Enclave would erase the keys if it&#x27;s updated.<p>It&#x27;s a pretty huge flaw if the firmware can be updated and the keys preserved without first validating with the passcode.
