🌀 MacGauge v1.4.0 — Crash-Safe Fan Control

The helper now protects you even when the app can't: a dead-man watchdog returns your fans to macOS control if the app ever crashes while driving them.

Added

• Crash-safe fan control: if the app stops responding (a crash, a force quit) while fans are under manual or curve control, the privileged helper now hands control back to macOS after three minutes of silence — fans no longer stay pinned at the last target until the next launch.
• Quitting normally with "restore automatic on quit" disabled keeps manual control exactly as before: the app explicitly releases the watchdog on a clean exit.
• Time asleep never counts toward the silence window, so the watchdog cannot misfire when the Mac wakes up.
• Helper protocol v5 — the app upgrades an older running helper automatically; no reauthorization needed.

Full details: CHANGELOG

⚠️ MacGauge changes how your Mac manages its own cooling. Lower fan speeds mean higher temperatures. Use conservative settings unless you monitor temperatures actively.
