Hi, The tokend must be installed in a specific system directory(/System/Library/Security/tokend?). With MAC OS 10.11 the introduction of rootless protection prevents from installing our tokend on this system specific directory unless the MAC OS is 'jailbroken' by disabling the rootless protection. Once the protection is disabled the tokend works as normal. What is the supported procedure to install a tokend on MAC OS 10.11 without disabling rootless protection, is that supported ?
