하루 종일 쓰는 배터리 프로필, 배터리 상태, MacBook Pro의 팬 곡선.
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
하는 일
- 프로필은 세 가지입니다. "하루 종일 배터리"는 동기화 앱과 업데이트 도구를 고효율 코어로 옮기고 Docker가 유휴 상태일 때 일시 정지합니다. "균형"은 아무것도 추가하지 않습니다. "최고 속도"는 느려지게 하는 것을 더하지 않으며, 팬 제어가 켜져 있으면 "더 시원하게" 팬 곡선을 사용합니다. 각 프로필은 규칙 화면에서 읽어 볼 수 있는 규칙 묶음입니다.
- 전원을 연결하거나 분리할 때 프로필을 전환할 수 있지만, 사용자가 동의한 뒤에만 합니다.
- 배터리 사이클 수, 정격 사이클 수, macOS의 배터리 충전 최적화가 충전을 억제하고 있는지 여부를 보여 줍니다. Hedroom은 읽기만 하고 바꾸지는 않습니다.
- MacBook Pro에서는 선택한 팬 곡선을 실행합니다: "조용함", "더 시원하게", "최대", 또는 직접 정한 2~5개의 점. Hedroom이 종료되면 팬은 자동 제어로 돌아갑니다.
What it will not do
- 저전력 모드를 건드리는 일. 그것은 계속 사용자가 직접 정하는 스위치입니다.
- "시작"을 누르기 전에 팬을 구동하는 일, 또는 팬 자체의 최소값과 최대값을 벗어나는 속도를 설정하는 일.
- macOS의 열 보호와 다투는 일. macOS가 "높음" 또는 "위험" 열 상태를 보고하면 Hedroom은 팬 제어를 돌려줍니다.
- Hedroom이 없어진 뒤에도 팬을 강제로 둔 채로 두는 일. Hedroom이 종료되거나 충돌하거나 10초 동안 응답하지 않으면 도우미가 팬을 자동 제어로 되돌립니다.
Limits
- 팬 제어에는 관리자 권한으로 실행되는 작은 도우미가 필요합니다. 시스템 설정 › 일반 › 로그인 항목에서 승인해야 합니다. Hedroom의 다른 기능에는 필요하지 않습니다. Hedroom은 팬 곡선을 켤 때만 승인을 요청합니다.
- MacBook Pro만 해당합니다. MacBook Air에는 팬이 없고, 다른 Mac은 팬을 자동 제어로 유지합니다.
- 팬을 강제할 수 없는 Mac에서는 팬이 자동 제어로 유지되며 Hedroom이 그렇다고 알립니다.
- Hedroom은 어떤 곡선에 대해서도 온도나 소음 결과를 주장하지 않습니다. 실시간 측정값을 보고 직접 판단하세요.
무료 또는 Pro
팬 속도, 온도, 배터리 상태, 프로필을 보는 것은 무료입니다. 프로필을 켜는 것과 팬 곡선을 실행하는 것은 Pro 기능입니다.
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.
