Profils de batterie pour toute la journée, santé de la batterie et courbes de ventilateur sur MacBook Pro.
The problem
On battery, a few background apps decide how long the day lasts: a sync client busy in the background, an updater that wakes at a bad moment, Docker left running. And when a MacBook Pro gets loud, you cannot see why or choose how it should respond.
Power & fans bundles the gentle fixes into three profiles you can read, shows battery health and fan speeds, and on a MacBook Pro lets you pick a fan curve, with the fans handed back to macOS whenever anything looks wrong.
How it works
- Pick a profile. All-day battery moves sync apps and updaters to the efficiency cores and, when Docker is idle, asks before pausing it. Balanced adds nothing. Full speed adds no slowdowns and uses the Cooler fan curve if fan control is on.
- Read the rules. A profile is a bundle of ordinary rules. They show in Rules, go through the same safety checks and get their own receipts. Low Power Mode stays your switch.
- Optionally switch by itself. After you agree once, Hedroom changes profile when you plug in or unplug, once the power source has stayed put for 10 seconds.
- Choose a fan curve (MacBook Pro). Quiet, Automatic, Cooler or Max, or your own 2 to 5 points. Starting one needs Hedroom's small helper, which asks for your approval in System Settings the first time.
- Hand the fans back. Every 2 seconds the loop reads the temperature and sets targets inside each fan's own limits. It returns the fans to automatic when you press Stop, when Hedroom quits, when the Mac sleeps, on any error, and when macOS reports a serious or critical thermal state.
What you will see
Three profile cards, the active one highlighted, with a footnote such as "Turns on 3 rules" or, while on, macOS's own estimate of time left. Below them, the fan card: preset buttons, a chart of your curve against an illustration of Apple's automatic one, and Start and Stop. A live tile shows fan speed and the die temperature, which on Apple silicon is usually one reading that Hedroom labels CPU. A battery health card shows capacity, cycles against rated cycles, and whether macOS Optimized Charging is holding the charge.
On a MacBook Air, or any Mac without fans, the fan section says "This Mac has no fans" and does not ask for the helper. On other Macs with fans it says fan curves are for MacBook Pro. If the helper is not approved yet, a card explains how to approve it.
A worked example
Example, not real data
Before a long day away from the charger
Say you pick All-day battery in the morning. Hedroom turns on its rules: sync clients that use lots of CPU in the background move to the efficiency cores, updaters on battery go there too, and when Docker is idle Hedroom asks before pausing it. Hedroom only pauses an app on its own when its library marks that app safe to pause. You can read each one in Rules.
As the day goes on, each time a rule acts it writes a receipt with the measured change in that app's watts or CPU. Hedroom does not predict how many hours you will gain: the card shows macOS's own estimate and the receipts show what the rules measured. If a rule does nothing for you, the usual "not helping" flag appears after three receipts.
Details and limits
Ce qu’il fait
- Propose trois profils. « Batterie toute la journée » déplace les apps de synchronisation et les outils de mise à jour vers les cœurs d’efficacité et met Docker en pause quand il est inactif. « Équilibré » n’ajoute rien. « Pleine vitesse » n’ajoute aucun ralentissement et utilise la courbe de ventilateur « Plus frais » si le contrôle des ventilateurs est activé. Chaque profil est un ensemble de règles que vous pouvez lire dans Règles.
- Peut changer de profil quand vous branchez ou débranchez, mais seulement après votre accord.
- Affiche les cycles de la batterie, les cycles nominaux et si le chargement optimisé de la batterie de macOS retient la charge. Hedroom lit cela et ne le modifie pas.
- Sur MacBook Pro, exécute la courbe de ventilateur de votre choix : Silencieux, Plus frais, Max, ou vos propres 2 à 5 points. Les ventilateurs repassent en automatique dès que Hedroom quitte.
What it will not do
- Toucher au mode économie d’énergie. Il reste votre interrupteur.
- Piloter les ventilateurs avant que vous n’appuyiez sur Démarrer, ou régler une vitesse en dehors du minimum et du maximum du ventilateur.
- Lutter contre la protection thermique de macOS. Si macOS signale un état thermique élevé ou critique, Hedroom rend les ventilateurs.
- Laisser les ventilateurs forcés après la disparition de Hedroom. L’outil d’assistance les remet en automatique quand Hedroom quitte, plante ou cesse de répondre pendant 10 secondes.
Limits
- Le contrôle des ventilateurs nécessite un petit outil d’assistance qui s’exécute avec des droits d’administrateur. Il demande une approbation dans Réglages Système › Général › Éléments de connexion. Rien d’autre dans Hedroom n’en a besoin. Hedroom ne le demande que lorsque vous activez une courbe de ventilateur.
- MacBook Pro uniquement. Un MacBook Air n’a pas de ventilateurs, et les autres Mac laissent leurs ventilateurs en automatique.
- Sur un Mac dont les ventilateurs ne peuvent pas être forcés, les ventilateurs restent en automatique et Hedroom le dit.
- Hedroom ne revendique aucun résultat de température ou de bruit pour une courbe. Vous voyez les mesures en direct et vous décidez.
Gratuit ou Pro
Voir la vitesse des ventilateurs, les températures, la santé de la batterie et les profils est gratuit. Activer un profil et lancer une courbe de ventilateur font partie de Pro.
The reason: reading your Mac changes nothing, while a profile or a fan curve changes how it behaves.
Questions people ask
Is it safe to control the fans?
Hedroom never sets a speed outside the fan's own minimum and maximum, and never drives the fans until you press Start. It gives them back to macOS if the Mac gets hot (a serious or critical thermal state), if anything fails, or if the helper does not hear from Hedroom for 10 seconds.
What is the helper, and why does it need admin rights?
Writing to the fan controller needs root. The helper is a small program inside the Hedroom app. It takes no file paths, runs no programs, and accepts connections only from Hedroom's own signature. It is registered only when you turn on a fan curve or raise the GPU limit, and you approve it in System Settings › General › Login Items. Approving the helper has the steps, and how to undo them.
Will it change Low Power Mode or charging?
No. Low Power Mode stays your switch. Hedroom reads battery health and Optimized Charging and changes neither.
Has fan control been tested on real hardware?
Fan control has been tested against simulated hardware, and the fan readings were checked read-only on one MacBook Pro. Writing to the fans needs a signed, notarized build, so checking it on each MacBook Pro model is a step before release. Hedroom is not released yet.
