Macbook pro can't start..

Macbook pro can't start. It says that I need to restart by pusing the power button longer and start again bypusing the star button.
But when it restarts, the same message will appear. Can anybody help?
Thanks,
Ronny.

Not quite sure what your situation is, but I'd probably start by booting from your Install DVD by holding C. Then selecting language, and going to Disk Utility, then Repair Disk & Repair Permissions.
A photo of the error msg would help if you have a camera handy.

My MacBook Pro can't Start

Hi,
This is so strange, my macbook pro can not start sometimes.
My macbook is an early version in 2011 with Mountain Lion installed now. The first time I can't start my mac in early Auguest.
I checked power, and pressed to start, but I only noticed that only the light flashed once, a very low sound made by the CD-drive I think (Truse me much lower than the normal sound). The strange things it started againt next day's morning, then I shut it down and went to work, and I couldn't start it in the evening. I have suffered this for three times. Normal to start in the morning, but dumped in the evening. So I disassembled it, but stoped after I toke down the battery and harddisk, then I cleaned the dust and assembled it back. what is surpise, It's back to normal until last Friday. Yes, It dumped again last Friday with the same symptom, and it seems my mac spent more time to recover itself this time. Last Monday evening it started when I feel hopeless, Tuesday was good, but on Wenday evening dumped again, and keep dumped by now.
Does anyone know what's the problem my computer has? Anything is wrong, power supply? Mainboard?
Any suggestion will be appreciated.

Not sure if it will help... but... have a look at this discussion...

Macbook Pro can only start up in safe mode

Hi,
My Macbook Pro has recently been freezing on a blue screen when I try and start up. I seem to only be able to start up in safe mode.
I have followed some instructions found regarding the blue screen issue: deleting some files out of library/startupitems folder
and managed to start up normally once, then soon after I got a message saying I need to restart my computer by holding down the power button.
I am now back to having to log in using safe mode.
Does anyone know how I can fix this?

My MacBook Pro can not start completely it stays on a blue scre

I restarted my MacBook Pro but left a USB plugged now it can not start completely it stays on a blue screen where I can see the pointer and sometimes a small icon which indicates its processing something. It has being like that for two days. I can not even turn it off I have to hold the bottom to force it to shut off.

i know this may be silly but i hope you removed the usb device while restarting.
If you did then hold up the option key as soon as you press the power button. It will bring you to a bootfolder selection choose your main partition and boot up. Alternatively if this does not help then do a PRAM and SMC reset. If these things fail then select recovery partition and go to disk utility and repair permisions for the main partition within the first aid section. If all else fails you would need to re install the osx, hope you have a back up.
Since you have not told us what model and year the mbp is if you have the recovery discs with you use disc 2 and read the insturctions on the disc as to what key you should hold.

When trying to install os x mavericks to my macbook pro as it started to install the computer now is stuck with the OS X Mavericks intall showing and I can't get out of it or force quit?

When trying to upgrade and install OS X Mmavericks to my Macbook Pro as it started to install the computer stopped the install and now is stuck with the OS X Mavericks intall window showing and I can't get out of it or force quit? I can not do anything else because this is stuck with this window/install screen showing. I have tried everything to get back to my regular desktop. I do not want to wipe the drive because I have photos on it that I want to save. So if there is any way to bypass this installer and get back to my regular desktop I would greatly appreciate the help.

Install or Reinstall Yosemite, Mavericks, Mountain Lion, or Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
How to Clean Install OS X Yosemite
OS X Mavericks- Erase and reinstall OS X
OS X Mountain Lion- Erase and reinstall OS X
OS X Lion- Erase and reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet if possible
because it is three times faster than wireless.

MacBook Pro can turn on and off, but does not start up. Stays on white screen with flashing folder icon, does not go to desktop.

MacBook Pro is not starting up. It just stays on a white screen with a flashing folder icon. Have tried restarting while holding the Option key, and the cursor becomes visible and movable, but it does not go to the desktop.

Hello Sonya_Rose,
I found this article when researching the issue you describe here named A flashing question mark appears when you start your Mac found http://support.apple.com/kb/ts1440.
Check the mouse and keyboard
This issue might occur if a mouse or trackpad button is pressed during startup. Make sure the button isn't pressed.
If the issue persists, shut down your Mac with its power button, disconnect any external mouse and keyboard, then turn on your Mac with its power button. If the flashing question mark issue persists, reconnect the keyboard and mouse.
Additional steps
If your Mac still starts to a flashing question mark, follow the steps below. If any step resolves the issue, you don't need to continue to the next one.
Select your Mac OS X startup disk with Startup Manager by restarting and holding the Option key. After your Mac starts up, restart again to verify that the flashing question mark does not appear.
If the issue persists, insert your Mac OS X installation disc. Be sure to either use the disc that came with your Mac, or, if you installed a later Mac OS X version from disc, use the newer disc.
MacBook Air note: On a MacBook Air, there are two options for starting up from Mac OS X media: Either connect a MacBook Air SuperDrive to the MacBook Air via the USB port and restart the computer, holding down the C key during startup, or use Remote Install Mac OS X to startup from a system software DVD that's located on a partner computer. Once started up from Mac OS X media, skip to step 3.
Restart the computer, then hold the C key during startup.
From the Utilities menu, choose Disk Utility. Don't click Continue.
Select your Mac OS X disk (named "Macintosh HD" by default) in the left side of the Disk Utility window.
Click the First Aid tab.
Click Repair Disk to verify and repair any issues with your Mac OS X startup disk.
After repairing the disk, try to start up normally.
Important: If Disk Utility finds issues it cannot repair, you may need to back up as much of your data as possible (or use Time Machine to back up to a different disk), then erase the disk and reinstall Mac OS X. You should back up important files and data before erasing a drive. Erasing deletes everything on the hard disk (including things on your desktop). Also, you can install Mac OS X onto an external disk, start from the external disk, and use Migration Assistant to transfer items from your usual internal Mac OS X startup disk to the external disk, then erase the internal disk and reinstall Mac OS X.
If the issue persists, and Disk Utility didn't find any irreparable issues, quit Disk Utility, quit the Installer, select your disk when prompted, and restart.
If the issue continues, reset PRAM. Note: After resetting PRAM, if the computer starts up normally, reselect the startup disk in the Startup Disk preferences.
If none of these steps resolve the issue, start up from the Mac OS X Installation disc and reinstall Mac OS X.
Regards,
Sterling

MacBook Pro won't start up, can I transfer photos to iMac any way

My MacBook Pro will not start up after latest update, I contacted Apple Support who said I needed a thunderbolt cable, I purchased this and tried to put my photos onto someone else's IMac, iit won't work any suggestions please.

You may take out the HDD and install it into an enclosure. Then connect it to a Mac via USB and If the HDD is functional, you should be able to take the data off of it.
Ciao.

My macbook pro can see my home wi-fi network but cannot connect to it. My iphone and ipad are connected to my home wi-fi so the problem is not the modem.

Wow, I tried to submit this as a problem and the computer lost the wifi connection again, so i lost the whole explanation i typed up.
I've turned off computer and modem multiple times.
When I tried to run the network diagnostic, the macbook pro gave me a "perhaps you are out of range error". I am sitting next to the modem.
My iphone and ipad are wonderfully connected to the home wifi network, so it cannot be the modem/router, correct?
If I am on the same floor as the router/modem then the macbook pro can see my home network but after tyoing in my password and trying to connect i get a "timed out" message.
If I move down one floor, then the macbook can see and connect to the wifi. I only have one modem on one floor.
Is there some sort of diagnostic I can run to see why this particular device (macbook pro) is behaving ths way? It just seems weird because the computer could connect to the wifi network yesterday while i was sitting next to the router.

SOLUTION!
I've been suffering from this problem for a few months. I tried everything suggested by everyone, and then, today, I had a mad idea.
I used to work in a room in the house that's about 12 metres away from the router. It's on the next storey up and horizontally about 8 metres away. The problem started when I began to work in the same room as the router.
Today I became so frustrated that for some reason I walked into a room about 8 metres away on the same level - Guess what? I connected with no problem at all. Feeling full of joy I walked back to the room where the router is located - Dropped internet connection within a few minutes! Walked back to the the room that's 8 metres away and, hey presto! I have a connection. I now realise that the problem was that I moved too close to the router.
I can think of no logical explanation for my experience, but empirically it seems to work. Does anyone have the faintest idea of why this should be the case? In the absence of an answer I think I may have to start believing in fairies at the bottom of the garden - I'm just off to set a meal for them.
By the way, I don't know if it has any significance, but the router is a BT Infinity router that has replaced the incredibly unreliable Virgin Media cable connection

TS3423 17" macbook pro won't start blue file with question mark is all that appears on the screen

My old macbook pro will not start up. Worked fine yesterday, today all I gat is the startup sound and a blank blue screen. After a while the screen shows a file folder icon with a question mark in it. Any ideas

Question (?) Mark, Blinking Folder, or Gray Screen at Startup
These are related but not identical issues. Their causes are outlined in Intel-based Mac- Startup sequence and error codes, symbols. Solutions may be found in:
A flashing question mark appears when you start your Mac
Mac OS X- Gray screen appears during startup
In most cases the problems may be caused by:
Problem with the computer's PRAM - See Resetting your Mac's PRAM and NVRAM.
Boot drive's directory has been corrupted - Repair with Disk Utility.
Critical system files are damaged or deleted - Reinstall OS X.
The disk drive is physically non-functional - Replace the hard drive.
Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
The main difference if you are using Lion or Mountain Lion is that you must first boot from the Recovery HD:
Boot From The Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Reinstall Snow Leopard Without Erasing The drive
1. Repair the Hard Drive and Permissions

After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install Mac OS X 10.6.8 Update Combo v1.1.
Reinstalling Lion/Mountain Lion Without Erasing The Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

Hi! My MacBook Pro won't start! HELP !!!

Hi! My MacBook Pro won't start! I have tried everything I can think of like Safe Mode (doesn't work), Recovery (does not find Recovery Drive), Booting with OS Snow Leopard Cd (doesn't work)...
I have really no clue about what to do now... I paid quite a lot of money for this computer and am pretty short of money nowadays! Would like to repair with help rather than having to take it to Apple Store.
Has anyone had this same problem?
All I get is white screen + grey Apple and spinning grey disk... it's 100% frustrating! Any help would be more than welcome since I think i've tried EVERY SUGGESTION on this Support Center and Youtube videos...
This MBP is from 2011, runs on OS X 10.6.8
I tried booting with OS X Snow Leopard CD, it didn't work! (my cd player works! recognizes the Snow Leopard CD, but then never opens it... goes back forever to the with screen + apple and spinning disk)
I don't care about the content, it's OK if i lose all DATA... I just want to bring this Mac BACK TO LIFE!
When i run coomand on root# fsck -fy --> RESULT = my HD was checked and seems to be FINE!
Thanks

Please make a Genius Appointment and take it in for service.

Yes and ask the repair tech.

Macbook pro isn't starting

my macbook pro isn't starting. it gets as far as the apple logo and loading wheel but does go any further, 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
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. The easiest way to deal with the problem is to boot from an external drive, or else to use either of the techniques in Steps 1b and 1c to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
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.
Step 7
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.
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 corrupt and the drive is probably malfunctioning. In that case, go to Step 6.
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 8
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 9
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.
Step 10
Repeat Step 9, 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 Time Machine or other backup.
Step 11
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a boot failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 12
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

My Macbook Pro won't start

This problem isn't like the others, it's completely different. So, I start my day like normal, I turn my Macbook Pro on, it starts loading at the startup screen. But this time, the loading bar suddenly dissapeared, so just the apple symbol and the wheel. Right afterwards, it shuts off. Not sleep mode, like completely shut down. I have already tried putting it in "Safe Mode", but that didn't help. And then when it's shut down, the charger light isn't on when it's plugged in. What do I do to solve this situation?

You don't need the menu bar to do an SMC reset. You don't do anything as the computer starts up, you just need to shut down the computer, which you can do by holding down the power button
Did you read the part for your computer? maybe you should read the article yourself...
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
