如何确定 Finder 中当前是否显示不可见文件？

Question

In a macOS application written in Swift or Objective-C and targeted for the Mac App Store, how to determine programmatically if invisible files are currently shown in the Finder? I have tried to call defaults read com.apple.finder AppleShowAllFiles using NSTask , but it does not work in the sandbox. Any help is greatly appreciated, thanks.

Answer 1

Finder

It's irrelevant if com.apple.finder AppleShowAllFiles contains false or true . You probably misunderstood how it activates file viewer with URLs.

Example:

• /Users/zrzka/.rustup
  • Finder is activated with content of the /Users/zrzka folder
  • .rustup folder is selected
• /Users/zrzka/.rustup/toolchains
  • Finder is activated with content of the /Users/zrzka/.rustup folder
  • toolchains folder is selected

Sandbox

You can ask Apple for temporary exceptions . Here's more detailed answer . But it really depends on what files/folders do you want to reveal.
