全天候的电池方案、电池健康，以及 MacBook Pro 上的风扇曲线。
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
它做什么
- 提供三个方案。“全天续航”会把同步 App 和更新程序移到能效核心，并在 Docker 闲置时暂停它。“均衡”不增加任何东西。“全速”不增加任何拖慢，并且在风扇控制开启时使用“更凉爽”风扇曲线。每个方案都是一组你可以在“规则”中读到的规则。
- 可以在你接上或拔掉电源时切换方案，但只会在你同意之后。
- 显示电池循环次数、额定循环次数，以及 macOS 的“优化电池充电”是否正在限制充电。Hedroom 只读取这些信息，不会更改它。
- 在 MacBook Pro 上，运行你选择的风扇曲线：安静、更凉爽、最大，或你自己设定的 2 到 5 个点。每当 Hedroom 退出，风扇都会恢复为自动。
What it will not do
- 触碰低电量模式。它始终由你来开关。
- 在你点按“开始”之前驱动风扇，或把转速设在风扇自身的最小值和最大值之外。
- 对抗 macOS 的散热保护。如果 macOS 报告较严重或严重的散热状态，Hedroom 会把风扇交还给系统。
- 在 Hedroom 不在之后让风扇保持被强制的状态。Hedroom 退出、崩溃，或超过 10 秒没有响应时，辅助工具会把风扇恢复为自动。
Limits
- 风扇控制需要一个以管理员权限运行的小型辅助工具。它需要在“系统设置”›“通用”›“登录项与扩展”中批准。Hedroom 的其他功能都不需要它。只有当你开启风扇曲线时，Hedroom 才会询问。
- 仅限 MacBook Pro。MacBook Air 没有风扇，其他 Mac 的风扇保持自动。
- 在风扇无法被强制控制的 Mac 上，风扇保持自动，Hedroom 会如实说明。
- Hedroom 不会对任何曲线声称有温度或噪音方面的效果。你看到的是实时读数，由你来判断。

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.
