Use a light touch when typing or using the trackpad and keep your hands and fingers relaxed. Avoid rolling your thumbs under your palms.

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 qualified 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 firm, comfortable support is best. Adjust the height of the chair so your thighs are horizontal and your feet are flat on the floor. The back of the chair should support your lower back (lumbar region). Follow the manufacturer’s instructions for adjusting the backrest to fit 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 flat on the floor, you can use a footrest with adjustable height and tilt to make up for any gap between the floor 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 reflections 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.

Learning More, Service, and Support

Your MacBook Pro does not have any user-serviceable parts. If you need service, contact Apple or take your MacBook Pro to an Apple Authorized Service Provider. You can find more information about your MacBook Pro through Help Center, online resources, System Information, and Apple Hardware Test.

Help Center

You can often find answers to your questions, as well as instructions and troubleshooting information, in Help Center on your Mac. Click the Finder icon, click Help in the menu bar, 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 Information, choose Apple () > About This Mac from the menu bar and then click More Info.

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.
