How to Reset a MacBook Air

The MacBook Air may require a reset from time to time. A basic reset is a common fix for frozen programs or a way to clear the RAM cache. A PRAM or System Management Controller (SMC) reset can resolve issues including frequent system freezes, no display, no sound or no fans running. Since the MacBook Air has an internal battery that is not readily accessible, the reset procedures for resetting the SMC are slightly different than for other MacBooks with removable batteries.

Instructions

Basic Reset

1. Locate the "Apple" icon in the upper-left corner of the screen.

2. Click on the on the "Apple" icon and select "Restart" from the drop-down menu.

3. Click "Restart" on the pop-up window that appears. Save and close any open files and programs if prompted.

Resetting PRAM

1. Click on the "Apple" icon at the top left and select "Shut Down." Click "Shut down" again when prompted and close any open programs if prompted.

2. Wait for the computer to shut down.

3. Press the power button to the right above the keyboard to power on the MacBook Air. Immediately press and hold the "Command-Option-P-R" keys until you hear the startup tone twice.

Resetting SMC

1. Turn off the computer. Plug the MacBook Air into its power supply and ensure that the power adapter is connected to a power strip or wall outlet.

2. Press the "Shift-Control-Option" keys along with the "Power" button at the same time.

3. Release the keys and press the "Power" button to turn the MacBook Air back on.

Tips & Warnings

• Be sure to hold down the relevant key combinations before the gray startup screen appears.
