How to use Apple Hardware Test
- Disconnect all external devices except keyboard, mouse, display, Ethernet connection (if applicable), and connection to AC power. Apple Hardware Test might display an error message if you don't disconnect all other devices.
- Make sure that your Mac is on a hard, flat, stable, well-ventilated work surface.
- Shut down your Mac.
- Turn on your Mac, then immediately press and hold the D key on your keyboard. Keep holding the D key until you see the Apple Hardware Test icon:
- 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, then press the Return key.
- To begin testing, click the Test button, press T, or press Return. Optionally select 'Perform extended testing' before beginning the test. This performs a more thorough test that takes longer to complete.
- When the test is complete, review your test results in the lower-right section of the window.
- To quit Apple Hardware Test, click Restart or Shut Down at the bottom of the window.

- Some Mac computers that shipped with OS X Lion v10.7 or later will start up from AHT over the Internet if your startup disk doesn't contain AHT, or if you hold down Option-D at startup. This requires an Internet connection over Ethernet or Wi-Fi.
- If you're using OS X Lion v10.7 or earlier and you can't get AHT to start, see if you have an OS X installation disc named “Applications Install Disc 2.” Insert the disc in your internal optical drive or external Apple SuperDrive before following the steps above. Or, if you're using a MacBook Air (Late 2010), plug the MacBook Air Software Reinstall thumb drive into your USB port instead.

Advantages start right at the installation screen. navigating and setting up your system start-up is intuitive, the process itself is amazingly fast. Despite the simplicity, you can use flexible access settings to run installation and setup in any way you want. The interface has been adjusted only slightly, adding a bit of stylish minimalism to previous incarnations with shades of white. An elevated element of iOs, launchpad screen, has been added to Lion making it more comfortable to access and operate various applications. Several interface and navigation functions have been combined into a more simple and functional Mission Control.
The system itself is not very demanding on the hardware, but only works with Core 2 Duo processors as a bare minimum. Unfortunately, some compatibility is lost in Lion, namely the Rosetta app that lets you run your Mac PPS applications with Intel chips.
Despite the shortcomings, all the basic functional programs for Mac work fine with Lion, including Office, printer software and much else. https://supernaldrop.weebly.com/what-cat40-pull-stud-for-dmg-mori-5100.html.
