General Troubleshooting

Update Software and Firmware

Important: Before you begin troubleshooting, ensure the correct version of OS X is installed, and check for and apply the

latest software and firmware updates. Computers sometimes exhibit symptoms that indicate the wrong version of OS X
system software is installed. Check Apple Support article HT1159: Mac OS X versions (builds) for computers to make sure
system build is correct for this computer model.

Firmware is the name given to software that is written into memory circuits such as flash memory, that will hold the software
code indefinitely, even when power is removed from the hardware. Firmware on Intel Mac computers is designed to be
updated if necessary by running the OS X Software Update check (available in the Apple () menu) while computer is
connected to the Internet.

For more information about firmware updates, refer to Apple Support articles:

HT1557: About firmware updates for Intel-based Macs
HT1237: EFI and SMC firmware updates for Intel-based Macs

Quick Check Procedures

Resetting the System Management Controller (SMC)

The System Management Controller (SMC) is a chip on the logic board that controls all power functions. If the computer is
experiencing any power issue, such as not starting up, not displaying video, sleep issues, or fan noise issues, resetting SMC
may resolve it.

For more information and instructions to reset the SMC on different computer models, refer to Apple Support article HT3964:

Intel-based Macs: Resetting the System Management Controller (SMC).

Note for iMacs: If you press the power button while inserting the power cord, the iMac will enter a mode in which the fans
run at full speed. For more information, refer to Apple Support article TS1433: iMac: Fans run at full speed after computer

turns on.

Resetting Parameter RAM (PRAM)

PRAM stores certain system and device settings in a location that OS X can access quickly. Exactly which settings are
stored in the computer’s PRAM varies depending on the type of computer as well as the types of devices and drives
connected. To reset PRAM:

Shut down the computer.

1.
Locate the following keys on the keyboard: Command, Option (Alt), P, and R. You will need to hold these keys down

2.
simultaneously in Step 4.
Press power button.

3.
Immediately press and hold Command-Option-P-R keys.

4.
Important: You must press this key combination before the gray screen appears.
Hold down keys until computer restarts, and you hear startup chime a second time.

5.
Release keys.

6.

For more information, refer to the following Apple Support articles:

HT1242: Mac OS X: What’s stored in PRAM
HT1379: Resetting your Mac’s PRAM and NVRAM

Starting Up in Safe Mode

Safe Mode is the state into which you can start up your Mac by performing a Safe Boot. Starting up into Safe Mode does
several things that can help troubleshoot and resolve software or directory issues that may exist on the startup volume. To
start up in Safe Mode:

Make sure computer is shut down.

1.
Press power button.

2.
Immediately after you hear startup sound, press and hold Shift key.

3.
Note: The Shift key should be held as soon as possible after startup sound but not before.
Release Shift key when you see the screen with a gray Apple and progress indicator (looks like a spinning gear). Note

4.
that booting into Safe Mode will take longer than a normal startup. During startup in OS X v10.4 through OS X v10.6.8,
you will see "Safe Boot" on the login window, which appears even if you normally log in automatically. In OS X v10.6
and later, a gray progress bar is also displayed on the bottom of the window during Safe Boot. During startup in OS X
v10.2 through v10.3.9, you will see "Safe Boot" on the OS X startup screen.
To leave Safe Mode, restart computer normally, without holding down any keys during startup.

5.

For more information, refer to the following Apple Support articles:

HT1564: Mac OS X: What is Safe Boot, Safe Mode?
HT1455: Mac OS X: Starting up in Safe Mode
TS1884: Safe Boot takes longer than normal startup

MacBook Air (Late 2010 and later) and MacBook Pro (Retina, Mid 2012 and
later): Sleep Status Tips

This computer model does not have a sleep LED. To troubleshoot without one:

Connect a USB device that has a power-on or activity LED. As power is restored to the USB bus and the system wakes
from sleep, the LED lights up.
Press Caps Lock key multiple times to wake computer from sleep.
Open display and press an alphanumeric key to wake computer from sleep.
A computer that has been asleep for an extended period can consume the remaining charge of the battery. Restore
power to computer with known-good power adapter, and check that MagSafe indicator light shows an in-progress
battery charge. The computer will boot from a hibernation file and start up from where it left off.
Resetting SMC instantly shuts down computer, with some side effects:

If computer is in sleep mode, it will reboot from a hibernation file.
If computer is booted to OS X during the SMC reset, data from open applications can be lost.
If computer is already shut down, there will be no side effects.

Note: Look for MagSafe indicator light to momentarily switch from off to green as SMC is reset and re-establishes
communication with power adapter; then change from green to orange if battery needs a charge.

Apple Service Toolkit (AST)

AST is a suite of diagnostic tools that checks Intel-based Mac hardware components, and provides detailed diagnostic logs
for review. AST runs on a local server, managing multiple Ethernet clients via NetBoot.

For more information, refer to Apple Support articles:

OP476: Latest Apple Service Toolkit download links and documentation
TP586: AST Reference Guide

Mac Resource Inspector (MRI)

MRI, which is part of AST, is a quick triage tool that checks for the presence of hardware and reports sensor readings.
Sensors are located on a variety of parts, including cables, fans, storage devices, power supply, display panel, and logic
board. Use MRI to help isolate failures and avoid unnecessary part replacements. MRI complements ASD, which is a more
in-depth repair verification tool.

Note: If all AST checks pass and a component is still suspected of fault, then verify with other diagnostic tools.

Cooling System Diagnostic (CSD)

CSD evaluates thermal sensors, fans, and heat sinks in late model MacBook Pro, MacBook Air, and iMac computers. It
either confirms correct operation or helps diagnose service issues. CSD is useful when assisting users with questions about
fan noise. This 3040 minute test, designed for use at the repair bench, fully checks thermal efficiencies in MacBook Air (13­inch, Late 2010) and later models. This test requires a USB ambient temperature sensor, available for order via GSX (part
number 9229911).

Trackpad Keyboard Mapper

The Trackpad Keyboard Mapper pairs the trackpad and keyboard of MacBook Air (Mid 2013 and Early 2014) models. To
ensure correct keyboard behavior, you must run this tool whenever you replace a Mid 2013 or Early 2014 trackpad. For more
information, refer to TP1016: AST Reference Guide: Using the Trackpad Keyboard Mapper.

Portables: Temperature Concerns

The normal operating temperature of this computer is well within national and international safety standards. Nevertheless,
users may be concerned about generated heat. To prevent an unneeded repair, you can compare a user's computer to a
similar running model, if available at your repair site. For more information, refer to Apple Support article HT1778: Mac

notebooks: Operating temperature.

MacBook Air (13-inch, Late 2010, Mid 2011, Mid 2012, Mid 2013, Early 2014):
Liquid Contact Indicators

To help discover accidental damage to the computer, the top case includes spill sensors called liquid contact indicators
(LCI). The sensors are visible only when the bottom case and most of the modules have been removed. Normally
represented by small white dots, the LCIs turn red when they have come in contact with liquid, such as an accidental spill.

For more information, refer to Apple Support article HT3400: Mac computers: About liquid contact indicators (LCIs) and

warranty coverage

The following image shows the general location of the LCIs in this computer. For LCIs that are not readily visible with the
bottom case removed, check the same area under cables or on the other side of modules.

Battery Liquid Contact Indicators

This image shows the location of LCIs on the underside of the battery module.

LCD Pixel Anomalies

When displaying a single color over the screen area, the LCD panel might show one or more pixels that are not properly lit.

LCD technology uses rows and columns of addressable points (pixels) that render text and images on the screen. Each pixel
has three separate subpixels—red, green and blue—that allow an image to render in full color. Each subpixel has a
corresponding transistor responsible for turning that subpixel on and off.

Depending on the display size, there can be thousands or millions of subpixels on the LCD panel. For example, the LCD
panel used in the iMac (27-inch, Late 2012) has a display resolution of 2560 x 1440, which means there are 3.7 million
pixels. Each pixel is made up of a red, a green, and a blue subpixel, resulting in over 11 million individual picture elements on
the 27-inch display. Occasionally, a transistor may not work perfectly, which results in the affected subpixel remaining off
(dark) or on (bright). With the millions of subpixels on a display, it is possible to have a low number of such transistors on an
LCD. In some cases a small piece of dust or other foreign material may appear to be a pixel anomaly. Apple strives to use
the highest quality LCD panels in its products, however pixel anomalies can occur in a small percentage of panels.

In many cases pixel anomalies are caused by a piece of foreign material that is trapped somewhere in the display or on the
front surface of the glass panel. Foreign material is typically irregular in shape and is usually most noticeable when viewed
against a white background. Foreign material that is on the front surface of the glass panel can be easily removed using a lint
free cloth. Foreign material that is trapped within the screen must be removed by an Apple Authorized Service Provider or
Apple Retail Store.

To determine if the display has an acceptable number of pixel anomalies, see the appropriate Apple Support article:

HT4044: About LCD display pixel anomalies for Apple products released in 2010 and later
HT1721: About LCD display pixel anomalies for Apple products released before 2010
