我们用 C 代码开发了一个小测试.app，它加载 (dlopen()) 一个简单的单函数 dylib 库（dylib 文件包含在 /Contents/Frameworks/ 下的 app Contents 中），其中 printf 的两个文本行到一个文本使用 xcode 12 在 /tmp/ 中的文件。
该应用程序（和内部的 dylib）使用与基于开发人员 ID 的证书绑定的配置文件进行签名。通过 Xcode 归档/导出工具的 UI，App 的运行时已针对 Developer ID（将在我们的网站上发布）进行了正确的强化、签名、公证和装订。
我们通过将它放在 /Applications/loadtest.app 下并通过双击执行它来验证它在我们的构建机器上是否有效（ /tmp/loadtest.log 已创建并正确打印条目。）
一旦我们将它下载到另一台 macbook（使用 osx 11.4 运行）上，它就不会执行（从 GateKeeper 收到“您没有打开应用程序的权限”消息），并且会因“终止原因：命名空间代码签名，代码 0x1”而崩溃"（请参阅下面的完整故障转储）。
在新的 macbook 上使用 spctl 检查：
spctl -a -t exec -v /Applications/loadtest.app:
“/Applications/loadtest.app：接受的来源=经过公证的开发人员 ID”
我们已经尝试更改应用程序的权限和属性（在互联网上找到了一些提示），但它没有帮助。有人建议重启机器（让它重新协调苹果的公证服务并下载最新的装订“票”），这也没有帮助。
如果我们在该测试 MacBook 上禁用 SIP，则应用程序现在运行，而不是在我们从网守收到有关“未知发布者”的警告并允许它之前，但我们需要我们的应用程序在启用 SIP 的情况下运行。
有没有人有任何提示或建议？我们联系了苹果，但从那以后没有收到他们的任何答复。
