ESD Related Tools

The following tools are needed to create an ESD-compliant work area:

ESD Wriststrap with clip/plug
Grounded ESD Mat
Wire Lead with Alligator Clips
Ground/Polarity Tester - A polarity tester allows you to make sure that any grounded plugs you use are correctly wired.
ESD storage bags to hold components


This tool allows you to magnetize your screwdrivers and other tools. It also allows you to demagnetize them in situations where a magnetized tool may harm components.

Needlenose Pliers

You may want to have both small and large pliers. Any pliers you get will need to have small tips.

Utility Knife or Razor Blade

In some situations, you may need to detach tape or cut plastic components.

ESD - Compliant Plastic Probe

This gives you a more precise means of moving components and cables. A good example of this is Apple's Nylon Probe Tool (black stick). Another name for this type of tool is "spudger".

Metric Ruler

Screws in portable Mac computers are referred to by their lengths in millimeters, and many are very small, requiring you to verify their lengths to ensure you are replacing the right screw. Also, having a straight edge can be useful in many situations.

Fine-point felt-tip permanent marker

You may be required to mark the locations of various internal components, such as thermal sensors, to ensure they are replaced in exactly the same positions.


Plastic tweezers are preferable since they are less likely to damage components. Be sure that they are ESD - compliant.

Paper Clip

There are some situations such as forcing open an optical drive tray or resetting an AirPort Base Station where only a paper clip will work.


Some portable computer models require a coin to unlock and remove the battery.


A multimeter is an instrument for measuring several different electrical parameters including most commonly voltage, current, and resistance.

A typical modern digital multimeter (also known as a DMM) has an LCD or LED digital numeric readout and various switches and/or dials to configure the multimeter to measure one of the available parameters, such as DC voltage, AC voltage, DC current, AC current, resistance, etc.

How to Use a Multimeter

1. Locate the battery on the logic board and identify its type, so you know what its expected voltage capacity should be. Most recent desktop Mac backup batteries should be 3.6 DC Volt capacity.

2. Identify the battery's positive and negative terminals (they are usually marked as + and - on the logic board, somewhere near the battery).

3. Turn on and configure the multimeter for correct voltage. Ensure the multimeter's display reads 0.0 __ Volts when not measuring anything.

4. Carefully touch the black (- negative) multimeter probe to the - negative battery terminal, and the red (+ positive) multimeter probe to the + positive battery terminal, being careful not to touch the probes to anything else or to each other.

5. Observe the multimeter's display. A dead Mac backup battery would typically read somewhere between 0.0 DC Volts and +0.5 DC Volts. By the way, even though the multimeter's leads are polarized, they can be safely connected to the battery backwards without harm; this would simply cause the multimeter's display to read -3.6 DC Volts instead of +3.6 DC Volts.

When Do You Use a Multimeter?

-You can measure a computer's backup or main battery DC voltage to determine if the battery is dead and requires replacement.

-Verifying DC Input Voltage.

-Verifying AC Input Voltage.

-Verifying Cable Connectivity (Ohms).

-Verifying Circuit Current (FlowAmps DC).

Safety Tips when Using a Multimeter

-Be sure the test leads and multimeter switch(es) are in the correct position.

-Never use the multimeter if the meter or the test leads look damaged.

-Never measure resistance in a circuit when power is applied.

-Never touch the probes to a voltage source when a test lead is plugged into the 10 A or 300 mA current input jack.

-To avoid damage or injury, never use the multimeter on circuits that exceed the maximum ratings specified for that meter.

-Never apply more than the rated voltage between any input jack and earth ground.
Be careful when working with voltages above 60 V DC or 30 V AC. Such voltages pose a shock hazard.

-Keep your fingers behind the finger guards on the test probes when making measurements.

-To avoid false readings, which could lead to possible electric shock or personal injury, replace the battery inside the multimeter as soon as the battery indicator appears.

ESD - Compliant Screw Box

Given the many screws in each Mac, you need a partitioned screw box with at least 12 partitioned sections.

Glue Gun/Glue Sticks

Some repairs may require that you glue down a component.

Cup Hook

One Power Mac computer has a plastic rivet that can only be removed via screwing in a cup hook and leveraging the hook with a screwdriver or wooden chopstick.

1600 Watt Hair Dryer

One portable Mac computer requires the hair dryer to heat component adhesive prior to component removal. Do not use a heat gun because it can be far too hot.


As computers use ever smaller components, getting enough light on where you are working is getting increasingly difficult. Also, some portable Mac computers require flashlights as part of troubleshooting video issues.

Dental Pick

A very sharp probe is sometimes useful when you need to move components small distances. Moving cables while checking routing is one example.

Alcohol Wipes and Pads

Some procedures require that thermal paste be cleaned off a component. These are the best tools for doing this.

Small Brush

This is useful for cleaning debris from MagSafe connectors.

Small Wire Cutter

In some situations, you may need to cut cabling.

Double Stick Tape

his is used to reattach components such as thermal sensors.


To test optical drives, you need to have a working CD or DVD. You may also want to have some blank discs on-hand to use in case the optical drive may damage discs.

Dental Mirror

This is useful for looking under or behind components.

CRT Discharge Tool

This is the tool required for discharging the CRT in an eMac computer. Details of its use are found in the Technician Safety course. It is no longer available directly from Apple but can be purchased from third parties.

iMac (Flat Panel)

iMac (Flat Panel)
Diagnostic Cables

These cables enable you to boot an original iMac (Flat Panel) while the bottom case is detached.

Without them, the internal cabling will not allow connections for power and data.

iMac (Flat Panel)
Torque Driver

This torque driver supplies a specific force to the screws that secure the bottom housing on the iMac (Flat Panel).

Using this torque driver ensures that the heat pipe in the computer will conduct heat properly from the processor.
