Q: Is the description of the Hardware Diagnostic Test completely inaccurate?

The steps describing how the Hardware Diagnostic Test works seem to be almost completely INACCURATE (see below). I've run this test 5 times this week on a new Macbook Air. There is NO test icon on screen at the beginning - just a black screen with a list of languages without any instructions. When you click on a language, a checkmark appears next to it, but nothing else happens. No AHT console ever appears - not at all during the entire process. You are never given the option of running the short vs. long test.  If you happen to hit RETURN (nothing tells you to do so), the test begins, but you would not know this because there is no progress bar and nothing happens on the screen for 3-5 minutes. If you happen to wait long enough, the results of the short test suddenly appear.

This is unacceptable.

Using Apple Hardware Test

1. Shut down your computer. Then, press the power button to turn it back on.
2. Press and hold the D key before the gray startup screen appears.
3. It takes a minute or so for AHT to start up and inspect your hardware configuration. While this is taking place, an icon appears on the screen:
   
4. When the process is complete, select your language and click the right arrow. If you aren't using a mouse, you can use the up and down arrows to select a language and then press the Return key.
5. The AHT console appears. You can choose which sort of test or tests to perform:
   • To perform all of the basic tests, click the Test button or press the "T" key or the Return key.
   • To perform a more thorough diagnostic test, select the "Perform extended testing" checkbox under the Test button before you click the Test button.
   Note: Your test results will appear in the window in the bottom-right of the console.
6. To exit AHT, click Restart or Shut Down at the bottom of the window.
