The Mac OS equivalent of DxDiag on Windows computers is the System Profile.
The System Profile is a diagnostic tool that shows all the technical information about your computer (graphics card model, amount of memory on the hard drive, operating system version).
No confidential information is collected.
How to get a system profile:
- Hold down the Option (Alt) key and select System Information in the Apple menu;
- Wait for System Profiler (or System Information) to finish gathering information;
- Open the File menu, select Save/Save As... and save the obtained information in a ".txt" file format;
- Attach the file to the request.
