Frequently Asked Questions
Is StatsCalm a subscription or a one-time purchase?
StatsCalm is a single, lifetime purchase on the Mac App Store. You pay once and own it forever with all future updates included. There are zero subscriptions and zero recurring charges.
Why does StatsCalm request Full Disk Access?
macOS sandboxing restricts apps from inspecting raw external disk health and process I/O. Full Disk Access allows StatsCalm to query S.M.A.R.T. hardware logs and notify you if a drive is failing. All diagnostics remain 100% on your device.
Does StatsCalm collect or send telemetry to external servers?
No. StatsCalm has zero analytics servers, zero tracking SDKs, and zero accounts. Your data never leaves your Mac.
Which macOS versions are supported?
StatsCalm runs on macOS 11.0 (Big Sur), macOS 12 (Monterey), macOS 13 (Ventura), macOS 14 (Sonoma), and macOS 15 (Sequoia), with native Universal Binary support for Apple Silicon and Intel Macs.
Why does an external SSD show “S.M.A.R.T. Unavailable”?
Certain budget USB-to-SATA enclosures use bridge chips (such as generic ASMedia or JMicron USB bridges) that block raw SCSI/ATA passthrough commands. High-quality Thunderbolt 3/4 enclosures (such as Intel JHL7440 / Goshen Ridge / ASM2464PD) fully support NVMe S.M.A.R.T. passthrough.
How does the Privacy Eye toggle work?
In the Network & Wi-Fi section, clicking the eye button masks your local IPv4, IPv6, router gateway, and hardware MAC addresses so you can safely record your screen or stream.
Why StatsCalm is the Mac hardware monitor that earns its menu bar slot
Drive health, not just free space
StatsCalm reads raw NVMe log pages and SAT SMART data (controller wear, Terabytes Written, spare capacity, media errors), including through Thunderbolt and USB enclosures that most monitors cannot reach. It warns you before an external SSD fails, not after.
Watts, temperatures, and Wi-Fi in one view
A live power ribbon shows how many watts come from the adapter, go to the Mac, and move through the battery and the SoC. A 60-second thermal timeline alerts you before throttling, and the Wi-Fi panel reports RSSI, noise floor, SNR, band, and real throughput.
A lifetime purchase with nothing phoning home
One purchase on the Mac App Store, no subscription, and no account. There are no analytics servers and no tracking SDKs: every reading stays on your Mac. The privacy toggle even masks IPs, DNS, and MAC addresses for screen recording and streaming.
