A Mac stuck on a black screen at startup may have a simple power, display, or connection problem—or it may be unable to load macOS. Start with the basics: check power and brightness, disconnect accessories, force the Mac to shut down, and start it again. If the screen remains black, use macOS Recovery to run Disk Utility, reinstall macOS, or arrange service if the Mac shows no signs of power.
Quick Answer
- Make sure the Mac is connected to power and the display is turned on.
- Disconnect hubs, drives, phones, and other accessories.
- Hold the power button or Touch ID button for up to 10 seconds to shut down the Mac.
- Wait a few seconds, then press the power button once.
- If the screen is still black, start macOS Recovery:
– Apple silicon: Press and hold the power button until Loading startup options appears.
– Intel: Turn on the Mac and immediately hold Command (⌘)-R. - In Recovery, use Disk Utility to check the startup disk. If necessary, reinstall macOS without erasing the disk.
- If the Mac has no startup sound, backlight, fan noise, or other response, check power and contact Apple or an authorized service provider.
Check Whether the Mac Is Actually On
A black screen does not always mean the Mac is off. Listen for a startup sound, fan activity, notification sounds, or keyboard backlight. Press the Caps Lock key to see whether its indicator responds. If the Mac seems active, the problem may involve the display rather than startup.
Check power and brightness
For a MacBook:
- Connect the Mac directly to a working power adapter and wall outlet.
- Leave it connected for several minutes.
- Press the brightness-up key several times. On some keyboards, you may need to hold Fn while pressing the brightness key.
- If possible, try another compatible charging cable, power adapter, or outlet.
For a desktop Mac:
- Confirm that the power cable is firmly connected to the Mac and the outlet.
- Make sure the external display is plugged in and turned on.
- Select the correct input source on the display.
- Check that the video cable is firmly connected at both ends.
- If available, test another cable, port, or display.
If the Mac has no response at all, follow the steps in this guide to fix a Mac that won’t turn on.
Disconnect accessories
A faulty USB device, dock, hub, external drive, or adapter can interfere with startup. Disconnect everything except:
- The power adapter
- The built-in keyboard and trackpad, if you are using a MacBook
- The display, keyboard, and mouse required to operate a desktop Mac
Remove external drives, printers, cameras, memory cards, hubs, and other accessories. Then try starting the Mac again. If it starts normally, reconnect devices one at a time to identify the item causing the problem.
Force the Mac to Shut Down and Restart
If the Mac is frozen on a black screen, force it to power off:
- Press and hold the power button or Touch ID button for up to 10 seconds.
- Release the button when the Mac turns off.
- Wait at least 10 seconds.
- Press the power button once to start the Mac.
Warning: A forced shutdown closes applications immediately and can discard unsaved work. Use it only when the Mac does not respond normally.
If the Mac starts after this step, allow macOS to finish loading. Avoid immediately opening many apps or reconnecting all accessories. If the black screen returns, continue with the startup troubleshooting steps below.
Try a Different Display Setup
A Mac may start successfully while sending an unusable signal to an external display. This is especially possible when using a dock, video adapter, or multiple monitors.
- Turn off the Mac.
- Disconnect all external displays except one, if possible.
- Connect that display directly to the Mac instead of through a hub or dock.
- Turn on the display first, then start the Mac.
- Try a different video cable or input on the display.
If the built-in screen on a MacBook remains black but an external display works, back up important files before investigating further. The problem may involve the built-in display, its cable, or related hardware.
Start the Mac in macOS Recovery
macOS Recovery is a separate startup environment with tools for checking the startup disk and repairing or reinstalling macOS. Use the method that matches your Mac.
Apple silicon Mac
This includes Macs with Apple silicon chips such as the M-series.
- Shut down the Mac. If necessary, hold the power button for up to 10 seconds.
- Press and hold the power button.
- Keep holding it until Loading startup options appears.
- Select Options, then select Continue.
- If asked, choose a user account and enter its password.
If the screen remains black and startup options never appear, check the display, power connection, and accessories again. On a desktop Mac, try connecting the display directly.
Intel-based Mac
- Shut down the Mac.
- Press the power button.
- Immediately press and hold Command (⌘)-R.
- Release the keys when you see the Apple logo or a spinning globe.
- Select a user account if requested, then enter its password.
If Command-R does not open Recovery, shut down the Mac and try again. Use the built-in keyboard on a MacBook when possible. Wireless keyboards may not connect early enough in startup.
For additional startup options, see this guide to starting a Mac in Safe Mode. Safe Mode loads only essential components and can help identify software that interferes with startup.
Repair the Startup Disk with Disk Utility
Once macOS Recovery opens, use Disk Utility to check the internal storage.
- In the Recovery window, select Disk Utility, then select Continue.
- In the menu bar, select View > Show All Devices.
- Select the internal physical drive or the top-level internal volume in the sidebar.
- Select First Aid, then select Run.
- Follow the prompts and allow the check to finish.
- Repeat First Aid for the volumes and containers shown under the internal drive if necessary.
- When finished, quit Disk Utility.
- Select Restart from the Apple menu.
First Aid checks the file system and attempts repairs. It does not recover every failed drive, and it cannot fix physical damage. If Disk Utility reports that the disk cannot be repaired, avoid repeatedly restarting the Mac. If you can access your files from Recovery, prioritize a backup or professional data recovery.
Reinstall macOS Without Erasing the Mac
If First Aid completes but the Mac still stops at a black screen, reinstalling macOS may replace damaged system files. In many cases, reinstalling macOS does not remove personal files, but you should still back up first whenever possible.
Warning: Do not erase the internal disk unless you have a current backup and understand that erasing removes data.
- Start macOS Recovery again.
- Select Reinstall macOS, then select Continue.
- Follow the onscreen instructions.
- Select the existing startup disk when asked where to install macOS.
- Keep the Mac connected to power and connected to the internet.
- Do not close the lid or interrupt the installation.
The installation may take time and the Mac may restart more than once. A temporary black screen during a restart can be normal, but do not force the Mac off while an installation is visibly in progress.
If the installer cannot find the startup disk, return to Disk Utility. A missing or inaccessible internal disk may indicate a storage or hardware problem.
Reset NVRAM on an Intel Mac
NVRAM is small memory that stores certain startup settings, such as the selected startup disk and display-related information. Resetting it can help with some startup and display problems. This procedure applies to Intel-based Macs; Apple silicon Macs manage these settings differently.
- Shut down the Mac.
- Turn it on and immediately hold Option-Command-P-R.
- Keep holding the keys for about 20 seconds.
- Release the keys and allow the Mac to start.
The Mac may appear to restart during the process. Resetting NVRAM does not erase personal files, but it may restore some startup or display settings to their defaults. See the NVRAM guide for more context.
When the Problem May Be Hardware
The issue is more likely hardware-related when:
- The Mac shows no response with a known-good power connection.
- The built-in and external displays both remain black.
- The Mac starts only when an external display is connected.
- The screen has visible cracks, lines, flickering, or backlight failure.
- Disk Utility cannot see the internal drive.
- The Mac shuts down immediately or repeatedly restarts.
- The problem began after liquid exposure, a drop, or another physical event.
Stop using the Mac if it has been exposed to liquid, becomes unusually hot, smells burned, or shows signs of battery swelling. Disconnect power when safe and arrange professional service. Do not open the Mac or attempt to press down on a swollen battery.
Troubleshooting
The Mac shows a cursor but the rest of the screen is black
A visible cursor suggests that the display is working and macOS may be stuck while loading the desktop. Force a shutdown, disconnect accessories, and start again. If the issue continues, try Safe Mode or macOS Recovery.
The screen is black only after entering the password
This can indicate a login item, display configuration, or damaged system component. Start in Safe Mode. If the Mac starts there, remove recently installed software or login items, then restart normally.
The Mac shows the Apple logo, then turns black
This is a startup process failure rather than a completely unpowered Mac. Try macOS Recovery and run First Aid. If the problem remains, reinstall macOS without erasing the disk. For problems that stop at the Apple logo specifically, see how to fix a Mac stuck on the Apple logo.
Recovery also shows a black screen
Check the display connection, try a direct connection instead of a dock, and disconnect unnecessary devices. On an Intel Mac, retry Command-R with a wired or built-in keyboard. If Recovery never appears and the Mac has no other visible activity, service may be required.
The Mac starts after several attempts
Back up important files as soon as you can. Intermittent startup may be an early sign of a failing drive, display, power adapter, battery, or logic board. Avoid delaying a backup while the Mac is working.
Frequently Asked Questions
Why is my Mac screen black but the Mac is on?
The Mac may be running with the display brightness reduced, sending video to another display, or stuck during startup. Check brightness, external display connections, and accessories. A responsive keyboard or startup sound indicates that the Mac may still be powered on.
Will forcing my Mac to shut down erase my files?
A forced shutdown does not normally erase files, but it can cause unsaved work to be lost and may interrupt file operations. Use it only when the Mac is frozen and cannot shut down normally.
Can I fix a black Mac screen without erasing my data?
Often, yes. Checking power, disconnecting accessories, starting in Safe Mode, running Disk Utility First Aid, and reinstalling macOS without erasing the startup disk are non-erasive approaches. Always back up important files before more advanced repairs.
Should I reset NVRAM on an Apple silicon Mac?
No special manual NVRAM reset is generally needed on Apple silicon Macs. Shut down the Mac completely and start it again, then use macOS Recovery if the problem continues.
When should I take my Mac in for service?
Arrange service when the Mac shows no response, the internal drive is missing in Disk Utility, the display is physically damaged, the problem follows liquid exposure or a drop, or Recovery cannot start after you have checked power and connections.
Final Thoughts
Start with power, brightness, display connections, and disconnected accessories before attempting repairs. If the Mac responds, macOS Recovery provides the safest next steps: run Disk Utility First Aid, then reinstall macOS without erasing the disk if necessary. Back up important files whenever the Mac starts successfully, and seek professional service when the screen, storage, or power system appears to be failing.
