The basic power-on steps for Mac, MacBook, and iMac
To turn on an Apple computer, locate the power button and press it once. On most Macs, the power button is in the top right corner of the keyboard. On iMacs and Mac minis, it is on the back or side of the machine. Press and release — do not hold it down. The computer will start up, and you will see the Apple logo appear on the screen within a few seconds.
The startup process takes between 30 seconds and two minutes, depending on your model and how long it has been since the last shutdown. During this time, you will hear the fan spin up and see the progress bar move across the screen. Let the computer finish starting up on its own — do not press the power button again.
Once the startup is complete, you may see a login screen asking for your password, or the desktop may appear directly if you are the only user on the machine. If you see the login screen, enter your password and press Enter to access your account.
Key Takeaways
- The power button on most Apple keyboards is in the top right corner; on desktop Macs it is on the back or side of the unit.
- Press the power button once and release — do not hold it down or press it repeatedly.
- Startup takes 30 seconds to two minutes; the Apple logo and progress bar will appear during this time.
- If you see a login screen, enter your password to access your account.
- If your Mac does not respond to the power button, check that it is plugged in and the battery is not completely drained.
Where the power button is located on different Apple models
On a MacBook Air or MacBook Pro, the power button is the small circular button in the top right corner of the keyboard, next to the Touch ID sensor if your model has one. Press it once with your finger and release when ready.
On an iMac, the power button is on the back of the monitor, usually on the lower right side. You may need to reach behind the screen to find it, or look for a small circular indent.
On a Mac mini, the power button is on the back left side of the unit. It is a small recessed button that you press with your finger or a thin object like a pen.
On a Mac Studio, the power button is on the back of the machine, near the power cable connection. On older Mac Pro models, the power button is on the front of the tower.
What to do if the power button does not work
If you press the power button and nothing happens, first check that the computer is plugged in. Look for the power cable connected to the back of the machine or the power adapter connected to your MacBook. If it is plugged in, the indicator light near the power port should glow amber or green.
If the light is off, the battery may be completely drained. Leave the MacBook or Mac plugged in for at least 15 minutes, then try the power button again. Some Macs take time to charge enough to power on.
If the computer is plugged in and the light is on but the power button still does not work, try a force restart. On newer Macs with Apple silicon (M1, M2, M3 chips), press and hold the power button for 10 seconds, then release. On older Intel Macs, hold down Command + Control + Power at the same time for several seconds.
Understanding the startup sequence and what you will see
When you first press the power button, the screen will remain black for a few seconds. This is normal. Then the Apple logo will appear in the center of the screen, usually in white or gray. Below the logo, a progress bar will begin to fill from left to right.
As the bar fills, the computer is loading the operating system into memory. You may hear the fan speed up or see the screen flicker slightly. This is all normal behavior. Do not interrupt the startup by pressing any keys or the power button again.
Once the progress bar completes, the login screen or desktop will appear. If you see the login screen, your computer has started successfully and is ready for you to enter your password.
Logging in after startup
If your Mac has multiple user accounts, you will see a login screen with account names and profile pictures. Click on your account name or picture, then type your password in the box that appears. Press Enter or click the arrow button to log in.
If you are the only user on the machine, you may go directly to the desktop without seeing a login screen. In this case, startup is complete and you can begin using the computer.
If you forget your password, you can reset it using your Apple ID. Click the question mark button on the login screen, then follow the prompts to verify your identity and create a new password.
Putting your Mac to sleep instead of shutting it down
If you plan to use your computer again soon, you can put it to sleep instead of shutting it down completely. Press the power button once — the screen will go dark, but the computer will remain powered on and ready to wake up quickly.
To wake a sleeping Mac, press any key on the keyboard, move the mouse, or press the power button. The screen will light up and you will return to where you left off, usually within a second or two.
Sleep mode uses much less power than running normally, so it is a good option if you will be away from your computer for a short time. If you will not use it for several hours or days, shutting it down completely saves more energy.
Frequently Asked Questions
How long should I wait after pressing the power button before the screen turns on?
The screen usually shows the Apple logo within 5 to 10 seconds. If nothing appears after 30 seconds, the computer may not be receiving power. Check the power cable and try again.
Is it bad to hold down the power button instead of pressing it once?
Holding the power button down will force the computer to shut down when ready, which can damage files or the operating system. Always press and release the power button quickly. Use a force restart only if the computer is frozen and not responding.
What does the amber light next to the power port mean?
An amber light means the battery is charging. A green light means the battery is fully charged. If there is no light at all, the computer is not receiving power and the battery may be completely drained.
Can I turn on my Mac remotely?
Most Macs cannot be turned on remotely from a powered-off state. However, if your Mac is in sleep mode, you can wake it remotely using Find My Mac or by sending a network command if Wake on Network Access is enabled in System Settings.
Why does my Mac take so long to start up?
Startup time depends on how many programs are set to open automatically, how full the hard drive is, and the age of the machine. Older Macs or those with many startup programs will take longer. You can speed up startup by removing unnecessary programs from System Settings under General > Login Items.
