白色褲子為什么會沾上藍色

You’re looking through Activity Monitor when you notice a process called blued. Should you be worried that this is running? No: it’s the process that powers Bluetooth on your Mac.

當您發現一個名為blued的進程時，您正在瀏覽Activity Monitor 。 您是否應該擔心此操作正在運行？ 否：這是為Mac上的藍牙供電的過程。

This article is part of our ongoing series explaining various processes found in Activity Monitor, like kernel_task, hidd, mdsworker, installd, WindowServer and many others. Don’t know what those services are? Better start reading!

這篇文章是一部分我們正在進行一系列的解釋活動監視器中發現，像各種Craft.iokernel_task ， hidd ， mdsworker ， INSTALLD ， WindowServer和其他許多人。 不知道這些服務是什么？ 最好開始閱讀！

Just to be clear: blued is not related to the Chinese gay dating app Blued (yes, researching this article was very confusing). Rather, blued is a macOS daemon, or background process, that handles Bluetooth connections on your Mac. To quote the blued man page:

只是要清楚：blued與中國同性戀約會應用程序Blued沒有關系(是的，研究本文非常令人困惑)。 相反，blued是一個macOS守護程序或后臺進程，用于處理Mac上的藍牙連接。 引用藍色手冊頁：

The Bluetooth daemon handles SDP transactions, link key management, and incoming connection acceptance.

The Bluetooth daemon handles SDP transactions, link key management, and incoming connection acceptance.

To summarize: any time you connect a speaker, mouse, keyboard, or even an Android phone to your Mac, blued is making that all happen behind the scenes.

總結一下：每當您將揚聲器，鼠標，鍵盤甚至Android手機連接到Mac時，都會發藍，這一切都在幕后發生。

For the most part, blued is not something that will take up a lot of your system resources. If you do see a persistent double digit CPU usage, something is probably wrong. Head to System Preferences, then Bluetooth, and try turning devices off one at a time by clicking the “X” beside its name.

在大多數情況下，blued不會占用大量系統資源。 如果確實看到持續兩位數的CPU使用率，則可能是錯誤的。 進入系統偏好設置，然后進入藍牙，然后單擊名稱旁邊的“ X”，嘗試一次關閉一個設備。

If resource usage goes down after you disconnect a specific device, there’s your problem. Google to see if anyone else is having this problem with your specific device, and consider also checking if there are any driver updates available.

如果在斷開特定設備的連接后資源使用率下降，則可能是您的問題。 Google查看其他人是否在您的特定設備上遇到此問題，并考慮還檢查是否有可用的驅動程序更新。

If you’re not using Bluetooth at all, turning Bluetooth using the “Turn Bluetooth off” button?will pretty much stop blued from using any system resources at all.

如果您根本不使用藍牙，則使用“關閉藍牙”按鈕關閉藍牙將幾乎完全停止使用任何系統資源。

If none of this helps, consider resetting the NVRAM. If that doesn’t help, resetting the SMC is a good last resort. If the problem persists, you might want to consult the experts at your local Apple Store, or any authorized Apple repair shop.

如果以上方法均無濟于事，請考慮重置NVRAM 。 如果那沒有幫助，那么重置SMC是一個不錯的選擇。 如果問題仍然存在，則可能需要咨詢您當地的Apple Store商店或任何授權的Apple維修店的專家。
