  • An enclave is defined as an area within a territorial boundary. So an exclave is an area outside of a boundary with ties to the main territory

    Essentially, Apple is trying to realize the security advantages of a microkernel without tossing the monolithic aspects of XNU.

They even make movie theater screens look bad. It’s not possible to have a projector give you true black. Better contrast sure, but not true black. There is a limit to contrast anyway since human eyes can only see so bright.
