linux-headers@6.8 for Mac

linux-headers@6.8 provides the header files corresponding to the Linux kernel, intended mainly for developers who need to compile kernel modules or work with kernel interfaces. Ordinary users rarely interact with it directly, but when building drivers or compiling certain software that depends on kernel headers, it becomes an essential foundational component. These header files describe the structures and interfaces exposed by the kernel, enabling external code to interact with the kernel correctly. It is a command-line development tool suited to people with some Linux experience who need to do low-level development or troubleshoot compilation issues.
