Why Is My Mac Working Again

There are lots of reasons why you might find that your Mac won't turn on, or your MacBook won't start up, but you probably merely want to get information technology working once again. We'll run through the various checks and changes to make to get your Mac to kick upwardly to yous can start using information technology again.

Read on for some simple tips that should get your Mac working, from the obvious stuff like checking the power connection, to performing a power cycle, starting in Recovery mode, and checking the file system. And if your Mac really is dead, nosotros'll also tell you where to plow side by side.

The fixes in this article apply to nigh recent versions of macOS. The menus and interfaces may look slightly unlike depending on which OS yous are running, but their functions are in essence the same. Similarly, if you accept an M1 Mac there are some changes to the way you perform sure functions – like starting up the calculator in Safe mode or Recovery, we'll detail these beneath.

1. Check your Mac turns on

First, let's find out if the trouble is that your Mac won't start upwards, or that it won't turn on – those might sound like the aforementioned thing, simply there'southward actually a big difference.

Press the Power button on your Mac. If y'all don't hear a startup chinkle, you don't hear any fan or drive dissonance, and there are no images, video, or visuals of whatever sort on your display, and then your Mac isn't turning on at all. Y'all're not even getting to the indicate where information technology refuses to start up.

A Mac that doesn't turn on calls for a different approach to one that doesn't first upwardly. If your computer doesn't plow on then you need to exercise the post-obit:

i) Check your power connection

Don't be the cliché: check that the ability is on and the Mac is plugged in correctly. Or if it'due south a laptop, be sure that the battery isn't expressionless – and if information technology needs charging give information technology a while to attempt to charge before terminal that information technology isn't going to work. If your MacBook won't charge read this.

2) Try a dissimilar power cable or adapter

It may be that the mistake resides with the ability cable. If you've got a friend with a Mac power cable that fits your motorcar, try information technology to come across if that solves the problem. If it does, it could exist a simple fix that involves finding a secondhand ability cable on eBay (although we propose against buying tertiary-party power cables that aren't fabricated by Apple tree, every bit they are much more likely to be faulty and possibly dangerous).

If you recently had a ability cut, that could be responsible: your power adaptor could have been damaged in a power surge and you lot may demand a new one.

Finally, it's possible that the cablevision is loose, and pulling it out and plugging information technology in once more will solve the problem. Just nosotros dubiety it volition be that easy.

Apple sells various cables for charging Apple Macs and laptops. You should find the one you need here: Apple tree power adaptors. Besides read: Which MacBook charger practise I need?

iii) Disconnect all accessories

Unplug all the accessories (such as printers and USB hubs) attached to your Mac. Information technology could be that one of your peripherals is causing bug with the startup sequence.

If you recently installed new RAM or a new hard drive, make sure they are correctly installed and compatible. (If possible, reinstall the old memory or difficult drive and see if that helps.)

If none of those steps work and then it's time to motility onto the next stage.

ii. Perform a Power Bike

If you aren't hearing whatsoever signs of life, you could perform a ability cycle, which involves forcing your Mac to restart after killing the power to it.

• On a MacBook you need to hold down the ability key for 10 seconds. Y'all'll usually hear a squeak as the Mac's ability is forcibly cut. Hopefully after waiting ten seconds and restarting, all will be well.
• If your Mac is a desktop you volition need to unplug it and exit information technology unplugged for at least 10 seconds before plugging information technology dorsum in and attempting to restart.
• For M1 Macs if you printing and agree the Ability push button you would eventually see Loading startup options – bold the Mac was working properly. If pressing and holding the power button does allow you to access the startup options then you can run through those options below to get your Mac up and running. Nosotros discuss this beneath.  We likewise discuss how to revive your M1 Mac using a second Mac and the Configurator app below.

If performing a power cycle on your Mac doesn't help, or if pressing the Power button on the M1 Mac doesn't open the start up options, there are a few other elementary things to endeavour out before moving on to the more complicated steps.

3. Check your brandish

If you're using a desktop Mac such as a Mac Pro or Mac mini this could apply to you. If you lot don't have a separate brandish plugged in you lot tin skip this step.

You could have a problem with the display you take plugged in, rather than the Mac itself. Have a listen to your Mac to come across if it's making any sounds during boot-upward.

It is possible that your Mac does turn on, simply doesn't boot upwardly because it can't access the display – if that'southward the case you are most likely having trouble with the display hardware (rather than a broader startup issue).

If you lot think it'southward a trouble with your monitor, then have a look at this Apple Support document for advice on troubleshooting a display. If your display isn't working the advice is to:

1. Check the power supply to the Mac (and the ability to the display if using a separate unit).
2. Confirm that all cables are continued deeply.
3. Remove all brandish extenders and switches, and whatsoever other devices between the Mac and monitor.
4. Unplug the video cablevision (if using a split up monitor) and plug it back in.
5. If using more than than one monitor in a 'daisy chain', unplug all monitors and test using just one.
6. If possible, effort to apply a different display, or a different adapter (use DVI instead of VGA, for example).
7. Apple also advises adjusting the screen resolution in System Preferences.

4. Kick up your Mac in Safe Boot

Safe Kicking limits what checks and functionality your Mac focuses on during startup, and performs certain diagnostics. It's rare, but sometimes you lot tin get your unhappy Mac to start upwards successfully with a Safe Boot, and then restart it normally, and everything returns to hunky-doriness. If you want more than assist with this step read: How to commencement a Mac in Safe Way.

• To enter Safety Mode on an Intel-powered Mac: Showtime your Mac upwards while holding down the Shift key. Safe Kick tin have a while to first (if information technology does work at all).
• To enter Safe Way on an M1-powered Mac: Press and continue to hold the power push button until you encounter the startup options appear on the screen. Choose the startup disk. At present press and hold Shift and and then click Keep in Safety Mode. And then release the Shift key. You volition see the words Safety Way in carte du jour at the top right of your screen.
• To get more than feedback virtually what'due south happening, you could start up an Intel-powered Mac while property downwards Shift, Command and Five: that enters both Safe Boot and something chosen Verbose Style, which spits out some messages about what Safe Boot is actually trying to do equally it goes.

At present you are in rubber manner we will discuss how to use Safe Mode to fix your Mac get-go up issues.

While you are Safe Mode the interface will look very slightly different, with blocks of colour rather than transparency. The biggest giveaway is the Dock at the bottom of the screen, such equally in the image beneath, for instance.

Once in Safety Style yous may be able to run sure checks (nosotros'll run through these below) and brand changes that could fix your Mac. For example you could reinstall macOS or update other software.

If y'all find y'all tin offset up in Prophylactic Mode it is probable that the effect is related to one of your startup items, in which case yous should get to: System Preferences > Users & Groups and remove all the items (click on -). Y'all could use trial and fault to piece of work out which startup particular is causing the problem.

5. Reset the PRAM / NVRAM

In the PowerPC days, we talked about resetting the PRAM. On Intel Macs, the term is resetting the NVRAM. The NVRAM in M1 Macs is reset automatically, merely there is a mode to reset NVRAM on the M1 Mac – we discuss that hither: How to reset NVRAM on an M1 or Intel Mac.

The name refers to special retention sections on your Mac that store information that persists even when the Mac is shut off, such as volume settings and screen resolution.

Resetting that data isn't harmful, but quite frankly it'southward also rarely genuinely useful. But it can't hurt.

Y'all might need to grow an extra finger or two for this one, or have a friend assistance you out. Here's how to reset the PRAM/NVRAM on your Intel-powered Mac:

1. Hold down all of these keys: Command, Selection (Alt), P and R, and turn on the Mac (information technology's the same keys to reset the PRAM).
2. Go on holding the keys down until you lot hear the Mac restart again.
3. Listen for a second reboot, and and so release the keys.

On M1 Mac resetting the NVRAM means using Final, the method is discussed in the article linked higher up.

In some cases, afterwards performing this step, your Mac volition restart normally. In other cases, you lot might instead see a progress bar on startup. If the progress bar fills up and then the Mac starts upwards, you're probably good to become. In some cases we've seen, however, the Mac shuts downward at around the halfway point in the progress bar.

6 . Reset the SMC

In some situations, you may need to reset your Mac's SMC (Arrangement Direction Controller). This is largely a concluding-ditch endeavour to fix the current version of macOS before attempting to recover the data and moving on to reinstalling the OS.

SMC is absent-minded from the M1 Mac so you can't reset it. All the same yous tin can alter the settings that the SMC used to await later. We talk over how to do this here: How to reset a Mac's SMC.

Here's what to do if you want to reset the SMC (Intel Macs):

On a Mac laptop:

1. Close down the MacBook.
2. Unplug and then reconnect the power cable.
3. Press Shift + Ctrl + Option/Alt keys and the power button at the aforementioned time.
4. At present release all those keys and the power button at the same time.
5. Y'all may see the light on the power cable flicker.
6. Restart your MacBook.

On a Mac desktop:

1. Shut downwards the Mac.
2. Unplug information technology.
3. Printing the ability push for v seconds.
4. Plug the Mac back in.
5. Turn on your Mac.

seven. Run Disk Utility in Recovery Mode

If your Mac is booting only the operating system isn't loading up, you may accept a corrupted drive. Luckily information technology is possible to fix this in Recovery Mode. We take a detailed tutorial on using Recovery Fashion hither, but we'll run thorough the nuts beneath.

Yet once again, accessing Recovery Mode is a little different on an M1 Mac (read most All the new ways of doing things on M1 Macs).

The first step is to run Disk Utility. On a Mac running Mountain Lion or after, which will be the vast majority of Macs, y'all can run Disk Utility by booting into Recovery Way.

• On an Intel Mac you need to make sure the Mac is turned off. If it's not responsive considering it's stuck on a grey, blue or white screen, only concord downwards the Mac'southward power button for several seconds until it gives upwardly and shuts off. (Here's what to practise to fix a Blue Screen of Death on a Mac.) Hold down the Command and R keys, and power the Mac back up again. Keep pressing Cmd + R while your Mac is booting up until you see the Apple logo.
• On an M1 Mac press and concord the Power button until the Mac starts up and eventually shows the starting time up options. Select Options > Continue to enter Recovery.

Now you are in Recovery mode here's what to practise:

1. Once your Mac starts in Recovery Fashion you will gain admission to Utilities. Click on the Disk Utility pick.
2. Locate your Mac'southward drive – probably Macintosh HD, select it.
3. Click First Aid.
4. If there are errors with your disk, Disk Utility should find them and volition either repair them automatically, or volition inquire if you would like to repair them. Click Repair Disk if this is the case.

In Recovery Mode you tin also do the following:

• Restore from a Time Machine backup.
• Get assistance online.
• Install or reinstall macOS (we discuss this beneath).

8. Revive a M1 Mac

If you have an M1 Mac and you all the same haven't been able to revive it, the next option to endeavour is to use a second Mac running Apple's Configurator 2 to update the firmware.

You will need a 2d Mac, a USB to USB cable, a web connexion and Apple's Configurator 2 software.

1. Connect the two Macs with a USB-C to USB-C or USB-C to USB-A cable.
2. Open Configurator 2 software on the working Mac.
3. Now on the non-working Mac press and hold the ability button while also pressing the following key combination: Right shift, Left Option/Alt, Left Control. You will need someone to help you unless you have gigantic hands because you besides demand to be pressing the Power Push at the same fourth dimension.
4. After nearly x seconds allow go of the keys, but keep pressing the Power button. Hopefully the M1 Mac will appear in the Configurator app on your second Mac past this betoken (the M1 Mac nonetheless won't show whatsoever screen activeness though).

The process is a little different for the M1 Mac mini.

1. In this instance you need to unplug it and look for about x seconds.
2. Printing and concur the power button.
3. Plug information technology in again, while however belongings the ability button.
4. Release the power button.

How to use the Configurator software to revive an M1 Mac.

1. The M1 Mac should be showing in the Configurator software on the other Mac. Select the M1 Mac you desire to revive.
2. Click on Actions > Advanced.
3. Select Revive Device.
4. This will revive the firmware on the M1 Mac.

ix. Check the file system

This pace is really kind of fun – at least when it's non your Mac that's under the weather. It's fun because it feels so geeky.

Before yous become too excited though, this isn't an choice for M1 Macs.

1. Shut the Mac off, and kickoff it up again while holding Cmd + Southward to launch in Single User Mode. You can release the keys when the intimidating blackness screen with messages in white text appears.
2. Wait until the control-line prompt appears, when all the text is done scrolling by. Then type fsck -fy and striking Render. And wait. Possibly for several long minutes.
3. Somewhen, after five different checks that have varying amounts of time, you should get to one of two messages: "The volume [your Mac's proper name] appears to exist OK" or "FILE SYSTEM WAS MODIFIED."
4. If you run into the first message, type reboot and press Render.
5. If you see the latter message, you need to run fsck -fy all over again. You can retype the command and striking Return, or press the Up pointer one time and then press Return.

If this doesn't work, and your Mac however doesn't kickoff up, and so move on to the next footstep.

x. Use Target deejay style to re-create files

This stride should be taken prior to reinstalling macOS and it depends on your fill-in situation. You practice make regular backups, or at least sync important documents, music and photos to the cloud, right?

If y'all're not sweating at the moment, and are confident in your Time Motorcar or other backup solution, and then skip to Step eleven below. But if you wish you'd backed up your Mac then now is the time to come across what you can salvage from the machine.

For this, yous'll need a 2nd Mac. If you haven't got 1 then ask a friend. Follow these steps to utilize Target Disk Mode:

1. Connect both Macs together using an Apple Thunderbolt cable (£39 from Apple). If yous accept an older Mac this same process works with FireWire cables.
2. Switch off your Mac.
3. Start upwardly your Mac while holding down the T button on the keyboard.
4. Continue property the T push button downwardly as you hear the startup chime and continue it pressed until the Thunderbolt icon appears on your screen.

This places your Mac in Target disk mode. In Target Disk way your Mac acts like an external bulldoze. Y'all should now hopefully see the hard bulldoze for your faulty Mac on your second Mac'south Finder.

You should be able to catch the files you demand from your unresponsive Mac, or even clone the unabridged difficult bulldoze to some other external drive.

eleven. Reinstall macOS

This is pretty drastic, only if you lot have tried everything else, then reinstalling the operating organisation could remove the issue that is stopping the Mac from starting properly.

Remember macOS Recovery from the footstep to a higher place? You can use it to reinstall macOS too.

1. Boot into Recovery mode as above (agree the Command and R keys while you outset up, or printing and hold the ability button if you lot are on an M1 Mac).
2. Once in Recovery click to install the latest Bone and follow the onscreen prompts.

Our commodity on resetting a Mac to factory settings has more information on wiping a Mac and reinstalling macOS.

12. Make a Genius Bar engagement

If yous've made it this far and your Mac notwithstanding doesn't work, you'll need to have it to an Apple Genius Bar to run into if they can help you set up it (or arrange for a repair nether warranty). Hopefully you have got enough data from your Mac then as to be able to dorsum upward, or go on working on a new Mac.
