Apple's recent modifications to its XNU kernel involve a restructuring aimed at enhancing security and efficiency. The inclusion of exclaves, which are secure enclaves or isolated execution environments, allows for better management of sensitive tasks while preventing the host system from interfering with those operations. This innovation draws parallels to Android's use of pKVM (Protected Kernel Virtual Machine) for running virtual machines securely, thereby emphasizing a growing trend towards isolating workloads to enhance both performance and security. As Apple's technology increasingly mirrors practices from competitive ecosystems, it reflects the industry's shift towards robust security frameworks capable of compartmentalizing processes.
