Common questions

The toggle doesn’t make my screen brighter

• MaxCandela needs a display with EDR headroom — MacBook Pro 14″/16″ (2021+), Pro Display XDR, or another HDR-capable display. On other panels there is no headroom to unlock.
• Check the right-click menu: it shows the live headroom your display is reporting right now.
• On battery-saver or when the Mac is hot, macOS temporarily lowers the available headroom; the boost follows automatically.

How do I cancel my subscription?

Subscriptions are managed by Apple: App Store app → your name → Subscriptions → MaxCandela → Cancel. Cancelling keeps the boost until the end of the paid period.

How do I get a refund?

Apple handles all refunds: reportaproblem.apple.com.

I bought Lifetime on another Mac — how do I unlock this one?

Make sure you’re signed into the same Apple Account, then right-click the ☀️ icon → Restore Purchases.

Is it safe for my display?

Yes — MaxCandela only uses the brightness range macOS itself exposes for HDR content and never bypasses the system’s thermal protection. Quitting the app instantly returns everything to normal.
