最近使用 Anki 记忆 COCA 词汇时，碰到此问题。
- 使用 Chrome 上的 Anki 取词插件（比如我用的 Online Dictionary Helper） 时，将单词添加至新卡片的功能需要依靠 AnkiConnect 插件连接桌面客户端与取词插件。
- 由于 Mac 系统的机制，会导致 Anki 客户端处于后台时，AnkiConnect 的进程被挂起。
- 结果是取词插件设置页面检测不到 AnkiConnect，或者检测到并设置好后短时间内连接又断开。
- 打开终端执行下面三行命令。
解决方法如下：
defaults write net.ankiweb.dtop NSAppSleepDisabled -bool true
defaults write net.ichi2.anki NSAppSleepDisabled -bool true
defaults write org.qt-project.Qt.QtWebEngineCore NSAppSleepDisabled -bool true
- 重启 Anki 客户端
官方文档原文：
Notes for Mac OS X Users
Starting with Mac OS X Mavericks, a feature named App Nap has been introduced to the operating system. This feature causes certain applications which are open (but not visible) to be placed in a suspended state. As this behavior causes AnkiConnect to stop working while you have another window in the foreground, App Nap should be disabled for Anki:
- Start the Terminal application.
- Execute the following commands in the terminal window:
defaults write net.ankiweb.dtop NSAppSleepDisabled -bool truedefaults write net.ichi2.anki NSAppSleepDisabled -bool truedefaults write org.qt-project.Qt.QtWebEngineCore NSAppSleepDisabled -bool true
- Restart Anki.
