You Just Got a New Mac and It Won’t Turn On
You’ve unboxed your sleek new MacBook or iMac, placed it on your desk, and pressed the power button. Nothing happens. The screen stays black, and there’s no familiar startup chime. A wave of panic hits. Is it broken already? Did you get a defective unit?
Or perhaps you’re a long-time Mac user, and your trusted machine, which you shut down last night, is now refusing to wake up this morning. You press every key, check every cable, and still, silence. Before you call Apple Support or start planning a costly repair, take a deep breath. The solution is almost always simpler than you think.
Turning on a Mac is fundamentally straightforward, but the exact method varies slightly between models. Modern Macs, especially those with Apple Silicon (M1, M2, M3, M4 chips), have refined the startup process, sometimes making it too subtle. This guide will walk you through every possible method, model by model, and troubleshoot the common reasons why your Mac might seem dead.
Locating the Power Button on Your Specific Mac
The first step is knowing where to press. Apple has moved the power button around over the years, integrating it into other components.
MacBook Air and MacBook Pro (2018 and Later, including Apple Silicon)
On these models, the power button is not a separate key. It is the Touch ID button located at the top-right corner of the keyboard, just to the right of the “F12” or “Delete” key. It is slightly larger than the other keys and has a fingerprint symbol on it. A single, firm press on this button will turn on your Mac.
MacBook Pro (2016-2017 Models with Touch Bar)
Similar to the newer models, the power button is the Touch ID button on the far right of the Touch Bar. The Touch Bar is the thin, black glass strip above the keyboard that replaces the function keys. Press the solid-state button at its right end.
iMac (24-inch, M1 and Later)
The power button is on the back of the computer, on the lower-left corner (when facing the screen). It’s a small, circular button. You’ll need to reach behind the display to press it.
iMac (27-inch and Older 21.5-inch Models)
The power button is traditionally located on the back of the machine, usually in the center-lower area. On some very old iMacs, it was on the lower-left corner of the bezel around the screen.
Mac Mini
The power button is a small, circular button on the back of the unit. On the latest Mac Mini models (M2 and later), it’s on the rear alongside the ports.
Mac Studio
Look for the power button on the back panel, near the ports. It’s a circular button with a power symbol.
Mac Pro
For the cylindrical “trash can” Mac Pro, the power button is on the top of the unit. For the newer 2019 Mac Pro tower, it’s on the front panel, near the top.
The Universal Method: Just Open the Lid
For any Mac laptop (MacBook Air, MacBook Pro), the simplest and most common way to “turn it on” from a completely shut down state is often to just open the lid. Modern Macs are designed to wake from sleep or even start up when you lift the display.
If your Mac was in sleep mode, opening the lid will instantly wake it. If it was fully shut down, opening the lid might trigger the power-on process on many models. Try this first before hunting for the physical button. Simply open the lid and wait 5-10 seconds. Look for any signs of life: a glowing Apple logo, a backlit keyboard, or a startup sound.
Step-by-Step: How to Properly Power On Your Mac
Follow this sequence to ensure you’re doing it correctly. This process applies whether your Mac is brand new, has been shut down, or is in a deep sleep state.
First, ensure your Mac is connected to a power source. For a desktop Mac (iMac, Mini, Studio, Pro), plug it into a working wall outlet. For a MacBook, it’s highly recommended to connect the MagSafe or USB-C power adapter, even if the battery isn’t empty. A stable power source eliminates many variables.
Next, press and hold the power button for approximately one full second. Do not just tap it lightly. Use a firm, deliberate press. You don’t need to hold it for 10 seconds at this stage—that’s for force shutdown, not a normal startup.
Now, listen and watch. You should hear a startup chime (on some older Intel Macs) or see the Apple logo appear on the screen. On Apple Silicon Macs, the startup is very quiet. The screen may remain black for 10-20 seconds before the logo appears. Be patient.
If you see the Apple logo, you’re good. The macOS will continue to load. You may be prompted to enter your password or use Touch ID to log in.
What to Do When Your Mac Still Won’t Turn On
If you’ve pressed the power button correctly and nothing happens—no lights, no sound, no logo—don’t assume the worst. Work through this systematic troubleshooting checklist.
Check the Basics of Power and Connections
This sounds obvious, but it’s the most common culprit. For a MacBook, the battery might be completely drained. Connect it to its power adapter and let it charge for at least 30 minutes before trying again. Ensure the power adapter is firmly plugged into both the Mac and the wall outlet. Try a different outlet or a different USB-C cable if you have one.
For desktop Macs, check that the power cable is securely connected to both the computer and the power strip or wall outlet. Verify that the power strip itself is switched on. If possible, plug the Mac directly into a wall outlet to bypass any faulty power strips.
Look for Subtle Signs of Life
On a MacBook, check for the charging indicator light. On models with MagSafe, the LED on the connector should glow amber (charging) or green (fully charged). On USB-C models, a small charging icon may briefly appear on the screen when you first plug it in, even if the machine is off.
Listen very carefully for any faint fan noise or a hard drive spin-up sound (on older models with hard drives). Feel the bottom of a MacBook or the back of an iMac for any warmth, which indicates it’s receiving power.
Reset the System Management Controller (SMC)
The SMC controls low-level power functions like turning on, battery management, and keyboard backlights. Resetting it can solve many power-related issues. The method differs between Intel and Apple Silicon Macs.
For Macs with Apple Silicon (M1, M2, M3, M4): There is no SMC to reset. Instead, a simple forced restart often clears the issue. Press and hold the power button (Touch ID button) for about 10 seconds, then release. Wait a few seconds, then press it again normally for 1 second to turn it on.
For Intel-based MacBooks with the T2 Security Chip: Shut down the Mac. Press and hold the right Shift key, the left Option (Alt) key, and the left Control key for 7 seconds. Then, while still holding those three keys, also press and hold the power button for another 7 seconds. Release all keys and wait a few seconds before pressing the power button to start.
For older Intel MacBooks without removable batteries: Shut down the Mac. Press and hold Shift-Control-Option on the left side of the keyboard, then press and hold the power button. Hold all four keys for 10 seconds, then release. Press the power button to turn on.
For Intel-based iMac, Mac Mini, Mac Pro: Simply unplug the power cord from the back of the computer. Wait 15 seconds. Plug it back in. Wait 5 seconds, then press the power button.
Try a Different Display or Keyboard
If you have a Mac desktop and you hear fans but see nothing on the screen, the issue might be with the display or video signal. Ensure the monitor cable (HDMI, DisplayPort, etc.) is securely connected at both ends. Try a different cable or a different monitor if available.
For MacBooks, connect an external monitor via HDMI or USB-C. If the external monitor shows a picture, the issue may be with your MacBook’s internal display or its connection.
Advanced Scenarios and Startup Key Combos
Sometimes your Mac turns on but gets stuck during the boot process. You can use special startup key combinations to access recovery or diagnostic modes.
If you see a flashing folder with a question mark, it means your Mac cannot find a valid operating system. Hold down the power button to turn it off. Then, turn it on and immediately press and hold the Command (⌘) and R keys until you see the Apple logo or a spinning globe. This boots into macOS Recovery, where you can reinstall macOS or restore from a Time Machine backup.
If you see a prohibitory symbol (a circle with a line through it), it indicates an incompatible or corrupted version of macOS. Again, use Command-R to start up from Recovery.
To run Apple Diagnostics (on Intel Macs) or Apple Diagnostics over the Internet, shut down your Mac. Turn it on and immediately press and hold the D key. Keep holding until you see a progress bar or are asked to choose a language. This utility will test your hardware for issues.
For Apple Silicon Macs, the process is similar: shut down, then press and hold the power button until you see the startup options window (showing your internal disk and Options). Click Options, then continue to see the Utilities window where you can run diagnostics.
Preventative Measures and Best Practices
To avoid future startup headaches, adopt a few simple habits. Avoid letting your MacBook battery drain to 0% and stay dead for extended periods. If you’re storing a Mac, shut it down and store it with about a 50% charge in a cool, dry place.
For desktops, use a high-quality surge protector to guard against power spikes that can damage internal components. Regularly update your macOS. Many updates include fixes for firmware and power management issues that could affect startup.
If you shut down your Mac regularly, know that modern Macs with fast SSDs and Apple Silicon start up in under 30 seconds. It’s often more practical to just put your Mac to sleep by closing the lid (for laptops) or selecting Apple menu > Sleep. This uses minimal power and allows you to resume instantly right where you left off.
When All Else Fails: Seeking Professional Help
If you’ve methodically tried every step above—checking power, resetting the SMC, attempting recovery mode—and your Mac remains completely unresponsive, it’s time to contact Apple Support. There could be a hardware failure, such as a faulty logic board, RAM, or power supply.
Before you go, gather your Mac’s serial number (it’s on the original box, receipt, or for MacBooks, on the underside of the case). Note down exactly what troubleshooting steps you performed. This information will help the support technician diagnose the problem faster.
If your Mac is still under warranty or you have AppleCare+, repairs will likely be covered. For older machines, you can visit an Apple Authorized Service Provider for an official diagnosis and repair quote.
Remember, the vast majority of “won’t turn on” issues are resolved with a proper power connection, a charged battery, or a simple SMC reset. What feels like a catastrophic failure is usually just your Mac needing a small, specific nudge to come back to life. By following this guide, you’ve equipped yourself with the knowledge to be that nudge, saving time, money, and a significant amount of stress.
