I have some files which stored in OS x sandbox container. Which I need is prevent user to copy/drag&drop these files outside.
I had read https://developer.apple.com/library/content/documentation/Security/Conceptual/AppSandboxDesignGuide/AppSandboxInDepth/AppSandboxInDepth.html#//apple_ref/doc/uid/TP40011183-CH3-SW6 about apple sandbox scheme. But have no help with me. Could you help me? Thx.
