APPLE SILICON · M1 → M5

See exactly what your Mac is doing while it runs AI.

SiliconMon is a live monitor for the M-series chip. CPU/GPU/ANE residency and watts, unified memory pressure, and per-process detection of the AI tool you're running — MLX, Ollama, llama.cpp, LM Studio, ComfyUI. Reads IOReport directly. No sudo, no helper, sub-1% CPU at idle.

Common questions

Why isn't this on the Mac App Store?

Because it uses Apple's IOReport private framework to read CPU/GPU/ANE energy directly. Apple's App Store review automatically rejects apps that link private frameworks. Same reason every other Apple Silicon monitor — Stats, iStat Menus, asitop, macmon, mactop — distributes outside MAS.

What does the trial unlock vs. Pro?

For 14 days everything is unlocked: full window, charts, AI Workloads card, history persistence. After that the menu bar item keeps working forever (live MEM / GPU / W) but the full window prompts for a license. The Pro license unlocks the full window again, indefinitely.

How does Apple Pay work for a non-MAS app?

Apple Pay works on the web — it's just a payment method on Stripe Checkout. When you click Buy, Stripe hosts the checkout page with the Apple Pay sheet baked in. You confirm with Touch ID / Face ID, get charged, and receive your license by email. Same UX as in-app purchase, different plumbing.

Where does the license live?

It's an Ed25519-signed token (~190 chars). Validated locally by the app using the public key embedded at build time — works fully offline. The signed payload contains your email, Stripe checkout id and issue date so you can reactivate any time, on any Mac, from the same email.

What does it actually cost to run?

Sub-1% CPU at idle on M1 through M5 chips, ~115 MB RSS, no background services, no daemons, zero network calls except auto-update checks against this site. Nothing leaves your machine.

Does it work on Intel Macs?

No. SiliconMon depends on the IOReport channels that only ship on Apple Silicon. M1 is the floor; M2 / M3 / M4 / M5 (including Pro / Max / Ultra variants) all supported.

Can I get a refund?

Yes — the 14-day trial is generous on purpose so you can verify it works for your setup before paying. If you bought without trying and it doesn't work for you, email contact@astrolexis.space within 14 days of purchase for a refund.

I lost my license email — can you resend?

Email contact@astrolexis.space from the address you used to buy. We'll resend the same key — no need to repurchase.
