为什么 Sierra 要求联系人（地址簿）许可？
Why is Sierra asking for Contacts (AddressBook) permission?
当人们使用我的应用程序过渡到 Sierra (MacOS 10.12) 时，OS 突然要求他们允许访问他们的联系人。我不知道为什么要这样做；它不会在任何以前的 OS 上执行此操作。
更重要的是，应用程序没有任何地方访问联系人；事实上，我根本没有加载 ABAddresssBook 框架。我已经搜索了地址和联系人的来源，但没有结果。 Xcode 显示没有 "Capabilities"。我使用的唯一第三方框架是 Sparkle。 （我静态 link mp4v2 库，它对 MacOS 一无所知。）仅供参考，此应用程序作为签名的第三方分发，而不是通过 App Store。它确实有一些嵌入式命令行可执行文件（例如 ffmpeg 等），同样不是 OS X 特定的。
我已尝试使用调试器查看是什么触发了通知。它显示了一个后台线程，其中执行一个块以获取 [ABAddressBook sharedAddressBook] 然后启动用户请求，但没有指示谁启动了该块。
对其他地方有什么建议吗？
这是应用程序和 Sparkle 的 otool -L 库列表。

原来是 Cocoa Lumberjack 日志框架。其中一种方法要求所有 类 查看他们是否已启用日志记录，并在日志记录上执行 "class_getClassMethod"。如果您使用 ABAddressBook 执行此操作，它会触发用户访问请求。
