Press the power button and wait for the startup sequence
To turn on your Apple computer, locate the power button and press it once. On most Mac models, the power button is in the top right corner of the keyboard. On older iMacs and Mac minis, it is on the back of the machine. Press firmly but do not hold it down — a single press is all you need.
After you press the button, you will see the Apple logo appear on the screen within a few seconds. The computer will then display a progress bar or spinning wheel as it loads. This startup process usually takes between 30 seconds and two minutes, depending on your Mac model and how much software is installed.
Do not press the power button again during startup. If the screen stays black for more than three minutes, your Mac may have a hardware issue and you should contact Apple Support or visit an Apple Store.

What happens after the Apple logo appears
Once the Apple logo shows on your screen, your Mac is loading its operating system. You will see a progress bar beneath the logo. This bar fills as the system loads — it does not mean anything is wrong if this takes a minute or more.
After the progress bar finishes, your Mac will display the login screen. This screen shows user account names and asks for a password. If you are the only user on the computer, your account name will already be highlighted. Type your password and press Enter to log in.
If you have never set a password, press Enter without typing anything. Your Mac will then load your desktop, and you will see the menu bar at the top and the Dock at the bottom of the screen.
Finding the power button on different Mac models
The location of the power button varies by Mac model. On MacBook Air and MacBook Pro computers, the power button is integrated into the Touch ID sensor in the top right corner of the keyboard. Press this button once to start the computer.
On iMac computers, the power button is on the back of the machine, near the bottom right. You may need to reach around the back to find it. On Mac mini, the power button is also on the back, typically on the right side near the ports.
On Mac Studio, the power button is on the back left side of the machine. On older Mac models from before 2015, the power button location varies — check the back or sides of your computer if you cannot find it on the keyboard.
What to do if your Mac does not start
If you press the power button and nothing happens, check that the power cable is plugged in firmly. For MacBooks, make sure the battery is charged — plug in the power adapter and wait 30 seconds before trying again. The charging light on the power adapter will glow when it is connected properly.
If the power cable is connected and the screen remains black after one minute, try a force restart. On newer Macs with Apple silicon chips, hold down the power button for 10 seconds until the screen goes black, then release and press it again. On older Intel-based Macs, hold Command + Control + Power for 10 seconds.
If your Mac still does not start after a force restart, the computer may have a hardware problem. Contact Apple Support through their website or visit your nearest Apple Store for diagnosis and repair.
Restarting your Mac if it is already on
If your Mac is already running and you want to restart it, click the Apple menu in the top left corner of the screen. Select "Restart" from the dropdown menu. A dialog box will appear asking you to confirm — click "Restart" again.
Your Mac will close all open programs and save your work if you have unsaved documents. The computer will then shut down and turn back on automatically. This process usually takes two to three minutes.
If you need to shut down your Mac completely instead of restarting, follow the same steps but select "Shut Down" from the Apple menu. The computer will turn off and stay off until you press the power button again.
Frequently Asked Questions
How long should I wait before my Mac fully starts up?
Most Macs start up within 30 seconds to two minutes. If your Mac is older or has many programs installed, it may take longer. If the screen stays completely black for more than three minutes, press the power button once more or try a force restart.
What if I forgot my password?
If you cannot remember your password, you can reset it on the login screen. Click the question mark icon next to the password field, or look for a "Reset Password" option. You will need to answer security questions or use your Apple ID to verify your identity.
Is it bad to force restart my Mac?
Force restarting is safe to do occasionally when your Mac is frozen or will not start normally. However, do not make it a habit — if you need to force restart regularly, your Mac may have a software or hardware problem that needs attention.
Can I turn on my MacBook without the power adapter plugged in?
Yes, if your MacBook battery has charge, you can turn it on without the power adapter. However, the battery will drain quickly. Plug in the power adapter as soon as you can to charge the battery and keep your Mac running.
Why does my Mac take so long to start up?
Startup time depends on how many programs are set to open automatically, how much storage your Mac is using, and the age of the computer. Older Macs with full hard drives start more slowly. If startup is taking longer than five minutes regularly, restart your Mac and check your storage space.
