The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This document describes missing hardware requirements on Mac devices that cause Secure Access ZTNA enrollment failure.
When attempting to enroll ZTNA, the posture error is displayed within Cisco Secure Client: "Posture Registration Failure. Endpoint Lacks Hardware Security. Please Contact Support if the Error Persists."
The end device is not supported due to failing to meet the Secure Enclave (Mac) enabled requirement.
For the ZTNA module to be installed and enrolled, there is a requirement for Duo Desktop (Device Health) to be installed and running within the end device. If the end device does not support Secure Enclave, the ZTNA enrollment fails.
Supporting logs can be viewed to confirm:
