推荐答案

这可能是由于NSOpenPanel的特殊体系结构.打开的面板会在自己的名为"Powerbox"的进程中运行，尤其是在将应用程序沙盒化的情况下. Powerbox没有API.即使您的应用程序没有被沙盒化，也请确保您对应用程序进行了适当的签名.

This is probably because of the special architecture of the NSOpenPanel. The open panel runs in it's own process called "Powerbox", especially if the app is sandboxed. The Powerbox does not have an API. Even if your app is not sandboxed, make sure you sign your app appropriately.

我想指出一些有关它的文档，但是整个Powerbox和Sandbox的文档很少，并且在引入时也实现得很差.

I'd love to point to some documentation about it, but the whole Powerbox and Sandbox are poorly documented and when introduced also poorly implemented.
