處理程序說明資料庫與說明庫更新

用平實的話解釋你在「活動監視器」中看到的名稱,大約每週根據一份經過簽名的清單重新整理一次。

The problem

Activity Monitor is full of names like mds_stores, cloudd and coreaudiod. When one of them is busy, you cannot tell whether that is normal, whether it will settle, or whether there is anything you can do.

The process library gives each common name a plain explanation: what it is, when it gets busy and what you can do about it. It ships inside the app, so it works offline. Hedroom's detectors read the same list, so they do not raise an alarm for something that is busy for a good reason.

How it works

  1. Look up. Search for the name you saw in Activity Monitor, or open it from an app's row with "What's this process?".
  2. Read four things. What it is, when it gets busy, what you can do, and whether it is Apple's. Apple processes are explain-only: there is no button.
  3. Detectors use it. The same list marks processes that are normally busy, such as Spotlight indexing, and apps that are normally large, so Hedroom does not flag them.
  4. Stay current. About once a week Hedroom downloads a newer signed copy. It checks the signature and that the version is newer before using it, and keeps the old copy if anything fails.
  5. Admit gaps. A name it does not know reads "Hedroom doesn't know this one yet.", with a link to search Apple's support site. It never makes up an answer.

What you will see

A search box ("Search a name you saw in Activity Monitor") and a list of results. The detail view of an Apple process reads "Apple process" and the name, then a plain explanation, "When it gets busy" and "What you can do", with a footer saying Hedroom never pauses, slows or quits Apple processes. If nothing matches, it says so.

In Settings › Privacy you see when the library was last updated and its version, with a Check now button that reports up to date, updated, couldn't reach, or couldn't verify.

A worked example

Example, not real data

mds_stores after restoring a backup

Say you restored files from a backup and mds_stores sits near the top of Activity Monitor for half an hour. You search for it. The library says it is the Spotlight search index, which gets busy "After big file changes, macOS updates, restoring a backup or plugging in a large drive."

What you can do: "Let it finish. It usually settles within an hour. You can exclude folders in System Settings › Spotlight." Hedroom raises no CPU finding for it, because the library marks it as normally busy, and offers no pause or quit, because it is Apple's.

Details and limits

它做什麼

  • 解釋某個處理程序或 App 是什麼,是否可以放心不管,以及它行為異常時該怎麼辦。
  • 內置在 App 中,所以可以離線使用。Hedroom 大約每週下載一次更新的簽名副本,也可以在「設定」›「立即檢查」中按需下載。
  • 使用新副本之前,會檢查簽名和版本。如果檢查失敗,它會保留舊的,並且不做聲。

What it will not do

  • 為了更新而傳送任何關於你的 Mac 的資訊。那只是一次普通的下載,沒有 Cookie,也沒有標識符。
  • 使用不是由 Hedroom 簽名的副本。
  • 在記憶體壓力嚴重時、低耗電模式下,或電池電量低於 20% 時自動檢查。

Limits

  • 說明庫涵蓋常見的名稱。遇到它不認識的名稱時,Hedroom 會說「Hedroom 還不認識這一項。」

Questions people ask

Does looking up a process send anything?

No. Lookups happen on your Mac. The weekly update is a plain download with no cookies or identifiers, and it sends nothing about your Mac.

Who wrote the explanations, and can I trust them?

Hedroom wrote them, in one file signed with an Ed25519 key. The app ignores a copy that is not signed by Hedroom or is not newer than the one it has. Each entry carries a reviewed flag, and a person has to review the text before a release ships.

Can I stop an Apple process from here?

No. Anything signed by Apple or in a system folder is explain-only.

Does it work offline?

Yes, the library ships inside the app. Updates are skipped at critical memory pressure, in Low Power Mode, or with the battery under 20%.
