Operating systems, infrastructure, emulation, and technical history.
The T2, introduced in the 2017 iMac Pro and rolled out through 2018, took boot security, storage encryption, and other sensitive functions off the main CPU.
An operational account of Catalina's zsh default: which accounts changed, what stayed on Bash, and how administrators could migrate without breaking scripts.
Apple's multi-year push to deprecate kernel extensions for user-space System Extensions and DriverKit, and what changes when a driver runs outside the kernel.
Why traditional plain-text syslog couldn't keep up with modern macOS, and how unified logging's structured, activity-tracing design fixes that.
Why macOS's kernel is neither a pure microkernel nor a pure monolithic kernel, and what that hybrid design actually buys in practice.
The IPC framework behind most of macOS's privilege separation, built on Mach IPC but designed to make secure, sandboxed communication the easy default.
Why emulator code, firmware, game images, dumping, distribution, and anti-circumvention are separate legal questions requiring local analysis.
A technical comparison of CPU interpreters and dynamic recompilers, including dispatch cost, translation blocks, timing, exceptions, and cache invalidation.
Why cycle-accurate emulation requires synchronized clocks, bus behavior, interrupts, video timing, hardware tests, and careful performance trade-offs.
A practical boundary between emulation and hardware-assisted virtualization, including CPU execution, devices, memory, timing, and hybrid systems.
