Noah

Noah is a macOS app that fixes what's actually wrong with your Mac — not by selling you a blind scan, but by finding the real cause. You describe the symptom in plain English ("my Mac is slow," "the fan won't stop," "Photoshop broke after the update"). Noah runs audited diagnostics, names the actual cause (usually a runaway process or login item, not junk), and proposes a one-sentence fix. Nothing runs until you tap approve — every action is shown before it happens, logged, and reversible. Noah never blind-deletes and never runs rm -rf.

Think of it as ChatGPT that can safely do the thing, instead of handing you Terminal commands you're scared to paste. The diagnosis and plan are always free; a fix is Noah Pass ($29 one-time) or Noah Guardian ($79/yr). The client is open source. macOS 12+, Apple Silicon and Intel.
