2012 Macbook Pro won't boot from CD and freezes in single user mode

I'm rebuilding a macbook pro. Everyting was fine until I tried to install Snow Leopard from the disk. It goes to the Apple symbol no spinning wheel and you can hear the drive working for a few seconds but then stops. I've also tried booting to sinlge user mode but it just freezes after Loading System\Library\Caches\com.apple.kext.cahces\Startup\Extensions.
I've tried resetting the PRAM as well.

If you have a 2012 MacBook Pro, you can't install Snow Leopard because it's not compatible, so it's normal that you can't start OS X.
Now, you have to install OS X Lion or Mountain Lion again. Hold Command, Option (Alt) and R keys while your Mac is starting to start into OS X Recovery, and reinstall OS X. After reinstalling OS X, you will be able to use your computer.
You can't run an older OS X version than the one that came with your computer, because of some reasons:
1. The hardware isn't compatible.
2. The firmware restricts the installation of older versions on the computer.
3. It's illegal: Apple doesn't allow you to install an older OS X version than the one that came with your computer, and it doesn't mind the method you use (a "normal" installation or a virtual machine)

Macbook Pro won't startup after Update

I guess everyone has been having problems around here. But I really have no clue what to do. I did not even know there was un update until I restarted. After I did it now my macbook pro won't start up. It makes that chime noise at the beginning and then it shows the apple and the spinning thing below it and I left it for 2 hours and came back and nothing had changed.
It my computer broken? Did I do something wrong? Have I lost all my stuff? Please help!

Yeah, I have had the exact same problem. it happen last friday. Also, i'm not sure if this is related or not but right before the update the computer for no reason in the middle of doing stuff it would tell me to force shut down by holding down the power button. not sure what to do. If i ship it out it will be about a 2 weeks before i get it back and if I take it in, they can't put it on the bench for about 5 days. its very frustrating and apple needs to figure something out for service.

Macbook pro won't startup. Stuck on apple logo with spinning wheel.

When I start up my 15 inch Macbook pro, it gets to the apple logo screen with the spinning gear underneath and it just stays there and does not startup. I have let it sit that way for up to an hour and it juts stays on that screen. Please help!

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see Step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 6
Boot into Recovery again. When the OS X Utilities screen appears, follow the prompts to reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
Step 7
Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a backup.
Step 8
A dead logic-board battery in a Mac Pro can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.
Step 9
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.

Macbook Pro won't startup after 10.9.1 update

Early 2013 Macbook Pro 13" retina running Mavericks.
Installed the 10.9.1 update and left it to do that and when I returned it had restarted in Bootcamp in Windows 8.1
Requested in Windows that it startup in OSX. On starting up OSX a message came up saying there was a problem starting.
It tries to startup a couple of times then a circle with a line though it comes up and it goes no further.
Tried booting into recovery mode to check permissions etc. in disc utility but that's not coming up either.
Any suggestions on what else to try?

Chose startup disk manually:
Hold the Command button during startup, then select your macintosh partition.
Reset the nvram:
Turn on your mac while holding Command-Option-P-R until the chime sounds for the second time.
Safe boot:
Boot while holding down the RIGHT shift button.
If you have a Time Machine, you can use that to restore.
Reinstall via recovery:
Hold down Command-R during boot, then hit reinstall in the menu.
Other than that, you'll have to go to a Genius Bar.
Hope this helps!

Help! My MacBook Pro won't go online

My MacBook Pro is connected to my home's wifi, but it doesn't go online. Every time i try to use safari it just stays blank, it won't go to any website. My family's PCs work just fine. I already tried from restarting my Mac to disconnecting my router and modem. Suggestions?

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, or by a peripheral device.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output andWi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

15" 2013 Macbook Pro won't startup

Hope someone can help,
My early 2013 15" Macbook Pro Running latest Yosemite public beta (10.10.4) won't boot past the password screen, it was working OK this morning went out for a while and when I got home it looked as though it had restarted. Entered my password and the screen changes to show my user picture and name but no loading bar. I've tried to reboot to safe mode however same thing, no loading bar just user picture & my name. Next I tried booting into the recovery screen (CMD + R+ Power) no luck there either, the apple symbol shows with no progress bar. Next tried booting to internet recovery (Option+CMD+R+Power) again nothing globe comes up but stops spinning after a second. I've tried resetting the NVRAM (Option+CMD+P+R) which reset the NVRAM but did nothing for the problem also tried booting in verbose mode (CMD+V+Power) entered password and got the following:

SOS help please. Macbook Pro won't turn on. Blinking Light

Hello to everyone this is my first post here and sadly its about a problem with my macbook pro.
The notebook in question is a 17'' Macbook Pro I bought in September 2008.
I simply closed it (without turning it off, just let it go on sleep) and took it with me as usual and when I tried turning it on again, it would not turn on.
I press the power button and I hear the hard drive/superdrive (not sure which of the two) start up and I see the sleep light turn on but after a few seconds its turns off again. If I hold the power button down for a few seconds the sleep light starts blinking and then the notebook turns off once more. In all cases the screen is black.
I tried everything here http://support.apple.com/kb/TS1365 and tried removing and re-installing the RAM and nothing changed.
Short of trying to re-install the RAM again I have no idea what to do. I won't be able to visit a Genius until after the 5th so any ideas/suggestions?

see http://support.apple.com/kb/HT2674 and http://support.apple.com/kb/HT2341 for some information about beeps and flashes.
In your case, though, jinnes, the slow blinks suggest that the computer is simply refusing to wake up from sleep.
One possible, though unusual, cause of this can be if you are using the computer with it stacked on top of a macbook. In this case the magnet in the macbook underneath activates the Hall effect switch in the MBP, making the latter think the lid is closed, and preventing wakeup. I've had this happen to me and it is quite unnerving at the time! Simply moving the MBP will fix it. see http://support.apple.com/kb/TS2917
The same effect could be generated by proximity to other magnets.
It is also possible , if this is not your situation, that the hall effect switch in your MBP is actually defective. It may be worth trying simply opening and closing the lid a few times to see if you can get it to activate.
Cheers

Macbook Pro won't startup after installing of 10.8.4

I just installed the 10.8.4 combo update package anf my Macbok Pro won't restart. After downloading the updates, the computer restarted itself, finished installing the updates, restarted itsalf again, anf when it gets to the gray screen with the Apple logo and the rotation icon underneath the logo, it just hangs. It goes no further than that. I let it run for about an hour before I tried to restart it manually, but I could never get it past that final screen. How do I fix it?

MacBook Pro won't startup - Folder with question mark appears

I have tried multiple times to startup my macbook pro (I am not sure if I have lion or not) and it will only come to a white screen. Sometimes an icon appears that is a folder with a question mark in the middle. I have an external hard drive, but everything is not backed up.
What is going on and what are some steps I can take to remedy this problem.
I have tried Command + R as well as Shift while starting up.

A flashing question mark or globe appears when you start your Mac

HELP!! Macbook Pro - Will not startup

I have a 17" Macbook Pro, it is about a year old. Just past warranty date. Of course there are no backups for it. Here is what happened:
For no reason when I start up my machine I get the apple, the spinning wheel and a hollow bar below the wheel. Then after about 4 seconds the machine shuts down. Happens every time will not restart.
I tried using the disk utility to repair the disk, but it indicates that the disk cannot be repaired. Tried to use the utility to copy disk contents. No go. If I format the disk I lose all of my contents...not good. Any suggestions
I have tries resetting the PRAM...nothing.

Suggest you try to mount your drive in target disk mode to see if you can access your data in order to retrieve it. After that, try reformatting the disk. Take it that far and see what happens....

Help!!macbook pro won't start up OSX after bootcamp remove vista drive

My Macbook pro (10.5.6) fail to boot into Osx after i used bootcamp to remove the vista drive.

Anyone know how to fix it ? i dont want to reinstall my os, but if i have to do so how can i recover some of my files from it ? Thanks~~~~~~~

You might try a PRAM reset followed by a Safe Boot:
http://support.apple.com/kb/HT1379?viewlocale=en_US
http://support.apple.com/kb/HT1455?viewlocale=en_US
With the PRAM reset, some people have recommended holding the keys down until the third chime.
Good luck!
