GetCurrentDir on MacOS

[Grahame Grieve]

If I set the working directory to {folder} in the Run Parameters dialog, shouldn't that {folder} be what I get back from SysUtils.GetCurrentDir ?

Because GetCurrentDir is returning / not the folder I set. Is that expected?

* Mac M1 Max / Monterey 12.5
* Lazarus 2.2.5 (rev lazarus_2_2_4-3-g564e1e8244) FPC 3.2.2 aarch64-darwin-cocoa

The system always forces the working directory of GUI applications to the root directory, probably to discourage you from trying to use it. You cannot/must not rely on it on macOS for GUI applications.

oh. thanks. Where is that documented? Should the dialog box disable the working directory in that case?

It's more that Apple doesn't mention using the working directory as a correct way to access any files: https://developer.apple.com/library/archive/documentation/FileManagement/Conceptual/FileSystemProgrammingGuide/AccessingFilesandDirectories/AccessingFilesandDirectories.html

Should the dialog box disable the working directory in that case?

It should still work fine for command line programs.

Lazarus can know which is which, right?

I don't know if it keeps track of that in the project file. There's also nothing preventing you from creating a GUI application using the template of a command line application (with or without the LCL).
