through Help Center, online resources, System Information,

and choose Help Center.
Online Resources
For online service and support information, go to
www.apple.com/support and choose your country from the
pop-up menu. You can search the AppleCare Knowledge
Base, check for software updates, or get help from Apple’s
discussion forums.
System Information
To get information about your MacBook Pro, use System
Information. It shows you what hardware and software is
installed, the serial number and operating system version,
how much memory is installed, and more. To open System

Apple Hardware Test
You can use the Apple Hardware Test (AHT) application
to help determine if there’s a problem with one of the
computer’s components, such as the memory or processor.
To use Apple Hardware Test: Disconnect all external devices
from your computer except the power adapter. Restart your
computer and hold down the D key as it starts up. When the
AHT chooser screen appears, select the language for your
location. Press the Return key or click the right arrow button.
When the AHT main screen appears (after about 45 seconds),
follow the onscreen instructions. If AHT detects a problem,
it displays an error code. Make a note of the error code before
pursuing support options. If AHT doesn’t detect a hardware
failure, the problem might be software related.

Not this
This
Change hand positions often to avoid fatigue. Some
computer users might develop discomfort in their hands,
wrists, or arms after intensive work without breaks. If you
begin to develop chronic pain or discomfort in your hands,
wrists, or arms, consult a qualied health specialist.
External Mouse
If you use an external mouse, position the mouse at the same
height as the keyboard and within a comfortable reach.
Chair
An adjustable chair that provides rm, comfortable support
is best. Adjust the height of the chair so your thighs are
horizontal and your feet are at on the oor. The back of the
chair should support your lower back (lumbar region). Follow
the manufacturer’s instructions for adjusting the backrest to
t your body properly.
You might have to raise your chair so that your forearms and
hands are at the proper angle to the keyboard. If this makes
it impossible to rest your feet at on the oor, you can use
a footrest with adjustable height and tilt to make up for any
gap between the oor and your feet. Or you can lower the
desktop to eliminate the need for a footrest. Another option
is to use a desk with a keyboard tray that’s lower than the
regular work surface.
Built-In Display
Adjust the angle of the display to minimize glare and
reections from overhead lights and windows. Do not force
the display if you meet resistance. The display is not designed
to open past 135 degrees.
You can adjust the brightness of the screen when you take
the computer from one work location to another, or if the
lighting in your work area changes.
