Same hardware path.
A far smarter
daemon.

Every serious battery manager on macOS — including AlDente — uses Apple's IOKit to control charging hardware. That's the correct, documented way. The difference is what ThunderVolt's daemon does with that access: real-time thermal monitoring, calendar-aware Smart Context, configurable hysteresis bands, and live sync to your iPhone and Apple Watch. AlDente does none of this.

Common Questions

Before you ask.

Apple Notarized. Uses documented SMC calls only. Fully removable — uninstall and charging returns to macOS defaults with no residue.
Both ThunderVolt and AlDente use Apple's IOKit to control charging hardware — that's how any serious battery manager works on macOS. The difference is what ThunderVolt's daemon does with that access: calendar-aware Smart Context, real-time thermal inhibit, configurable hysteresis bands, and an iPhone + Apple Watch companion app. AlDente is macOS-only and has none of these.
Yes. M1, M2, M3, M4, and Intel. Universal binary — no Rosetta required.
The daemon is fully removed. Charging returns to macOS defaults immediately. No residue, no locked settings.
No. ThunderVolt only controls when charging starts and stops — the same thing macOS does natively. Applying a charge limit extends battery life; it does not void warranties.
Yes. All data stays on your device and syncs privately via iCloud when using the iPhone or Apple Watch companion. Nothing is sent to ThunderVolt servers.
Install ThunderVolt Advanced and open it — the trial starts automatically. No credit card required. After 7 days, Pro features lock unless you activate a license key.
Yes. The companion apps let you set charge limits, enable Storage Mode, or trigger a top-up from your wrist or phone. Changes sync to your Mac via iCloud in under a minute.
