Wireless Diagnostics on macOS is a built-in tool designed to help troubleshoot wireless connectivity issues. When this tool is used, it generates a compressed file that contains diagnostic information, including logs about network performance and statistics related to the wireless environment.

The compressed file format is advantageous because it consolidates multiple files into a single, manageable package. This packaging allows for easier analysis and transfer, especially when sharing diagnostic data with support personnel. Additionally, storing this file in the /var/tmp directory is consistent with macOS's filesystem hierarchy, as that location is typically used for temporary files.

In contrast, a text file or log file would not condense multiple types of data into a single file format as effectively as a compressed file would. Configuration files, meanwhile, contain settings and preferences rather than diagnostic data, making them unsuitable for what Wireless Diagnostics produces. Thus, the choice of a compressed file saved in /var/tmp accurately reflects the function and utility of the output from Wireless Diagnostics on macOS.
