🚧 Optional: Metal Profiling

Week 2 requires reproducible benchmarks, not a GPU capture. The course’s full Metal profiling workflow depends on capture and visualization tooling that will ship with macOS 27, so those instructions are intentionally deferred until that release is available.

These materials are not required: gpudebug, an Xcode GPU capture, a .gputrace, screenshots, or profiling microbenchmarks to complete any current checkpoint. Continue from Day 2’s matched benchmark directly to Day 3’s quantized live-model integration.

When the macOS 27 workflow is added back, it will remain optional and will supplement—not replace—the ordinary synchronized benchmark and correctness gates.
