A few things
you might wonder.

More help ↗
Which Macs are supported?

The desktop preview targets macOS 11 or later, with separate Intel and Apple Silicon downloads. Available sensors and control features vary by model. macOS 26 and 27 have cross-version interface checks; older systems are not all physically validated.

Can I just monitor without changing anything?

Yes. Monitoring starts read-only, with fans managed by macOS. Hardware control requests administrator authorization when first used. Choose Auto to return control to the system.

Does showmac upload my readings?

The app processes readings and session history on your Mac. No account, advertising SDK or analytics service is built into the current app. Website access logs and voluntary support emails are covered separately in the privacy policy.
