Step 1:

Check that your Mac turns on first, let’s check that the problem is that your Mac won’t start up and not that it won’t turn on – it might sound confusing, but there’s actually a big difference.Press the Power button on your Mac. If you don’t hear a start-up chime, and you don’t hear any fan or drive noise, or if there is no images, video or visuals of any sort on your display, then your Mac isn’t turning on at all.

Step 2: Run Disk Utility in Recovery Mode

If you’re Mac turns on, and the display works, but it won’t boot, there could be many issues at play. But the one we like to rule out right away – or repair, if possible – is any problem afflicting the hard drive. The easiest first step on that front is to run Disk Utility.

Make sure the Mac is off. (If it’s not responsive because it’s stuck on a grey, blue or white screen, just hold down the Mac’s power button for several seconds until it gives up and shuts off.) Hold down the Command and R keys, and power the Mac back up again.

Click on Disk Utility and then click on your Mac’s built-in hard drive in the left column of Disk Utility. On the lower right of the Disk Utility window, click Verify Disk, and then wait while Disk Utility does its thing.

Step 3: Try to Safe Boot the Mac

Shut the Mac down, and start it up while holding down Shift. Safe Boot can take a while if it does indeed work. To get some feedback about what’s happening, you might choose to start up while holding down Shift, Command, and V: that enters both Safe Boot and something called Verbose Mode, which spits out some messages about what Safe Boot is actually trying to do as it goes.

Step 4: Fsck for fsck’s sake

Shut the Mac off, and start it up again while holding Command and S. You’re launching Single User Mode. You can release the keys when the intimidating black screen with messages in white text appears.
Wait until the command-line prompt appears, when all the text is done scrolling past. Then you’ll type fsck -fy and hit Return. And wait, possibly for several long minutes.

Eventually, after five different checks that take varying amounts of time, you should get to one of two messages:
“The volume [your Mac’s name] appears to be OK” or
“FILE SYSTEM WAS MODIFIED.”
If you encounter the first message, type reboot and press Return. If you see the latter message, though, you’ll want to run fsck -fy all over again. You can retype the command and hit Return, or press the Up arrow once and then press Return.

Step 5: Reset the NVRAM

Hold down all of these keys: Command, Option, P and R, and turn on the Mac, keeping holding the keys down until you hear the Mac restart again. In some cases, after performing this step, your Mac will restart normally. In other cases, you might instead see a progress bar on startup. If the progress bar fills up and then the Mac starts up, you’re probably good to go. In some cases we’ve seen, however, the Mac shuts down at around the halfway point in the progress bar.

Step 6: Reset the SMC
In some situations, you may need to reset your computer’s System Management Controller (SMC)

Step 7: Target disk mode
For this, you’ll need a second Mac. If you haven’t got one then ask a friend. Follow these steps to use Target Disk Mode:
1. Connect both Macs together using an Apple Thunderbolt cable (it also works with FireWire cables on older Macs).
2. Swift off your Mac (hold down the power button if necessary).
3. Start up your Mac while holding down the T button on the keyboard.
4. Keep holding the T button down as you hear the startup chime and keep it pressed until the Thunderbolt icon appears on your screen.

This places your Mac in Target disk mode. In Target Disk mode your Mac acts like an external drive. You should now, hopefully, see the hard drive for your Mac on your second Mac’s Finder. You can grab the files you need from your hard drive or even clone the entire hard drive to another external drive.

Step 8: Reinstall Mac OS X

Remember OS X Recovery from Step 2. You can use it to reinstall Mac OS X too. Boot into Recovery mode, and then click to install Mavericks and follow the on-screen prompts. See Use Recovery mode to restore your Apple Mac computer.

Step 9: Make a Genius Bar appointment
If you’ve made it this far and your Mac doesn’t work then you will need to take it in to an Apple Genius Bar to see if they can help you fix it (or arrange for a repair under warranty)?
