"#Exclaves land in MacOS

Nobody is really surprised that the MacOS 26.0.1 firmware image of the about to be released MacBook Pro #M5 reveals that Memory Integrity Enforcement (#MIE) on top of the ARM64 Enhanced Memory Tagging Extension (#EMTE) is used. Extremely surprising is however that Apple is now shipping the Secure Kernel (#SK) and #ExclaveCore / #ExclaveOS with MacOS. This means Apple's newest security boundary #Exclaves has finally arrived in MacOS."
