My MacBook Pro WILL NOT START. Powers on, grey apple screen loads then shuts off

Fairly new MacBook Pro with OXLion. When I try to turn on the computer, the startup noise and screen appear (grey loading screenwith apple icon). A loading bar at the bottom of the screen fills about a third up, then the computer shuts down again.
ANY HELP?????????

Power off the Mac, press option, command,power button. Just press them at the same time for a second. Then try power up. If still no joy, try a safe boot. With the Mac powered off, press power button and hold shift key down, this boot will take longer so be patient, continue to hold the shift key till you see the progress bar come up and the spinning gear, you can then release the shift key and let it finish booting. Your login window should come up try logging in. Check some of the applications and see if they seem to function correctly, in safe boot mode only essential OS applications are launched, if all is normal try powering off and rebooting in the normal mode. If all is well in safe mode itmight mean some third party software could be causing the problems.

Power it down by holding the power button down. Then try to power it up again. Post back. It would help if we knew what OS you are running, the model MBP...

The Macbook Pro will not start past the grey Apple logo screen? Any help will be most welcome?

The Macbook Pro 13, late 2009 will not start past the grey Apple Logo screen? Any help will be most welcome? Thanks

Have you tried booting with the install disc that came with your computer?
Find it and then run Disk Utility to verify your hard drive. If errors are found, try to repair the disk.
It sounds as if the hard drive might be failing.

My MacBook Pro will not start up with Command -R.

After starting with Command - R progress bar fills and disappears. The Apple symbol remains with the spinning wheel below. The start-up seems to stall at this point. Next steps?

Try booting whilst holding down the option (alt) key - you should see your Recovery partition as a bootable partition.

MacBook Pro will not start, appears to load but does not

Removed Trend Microsystems, installed Norton 360 multi device, MacBook has unsuccessfully restarted since. Turn on...shows apple logo, runs to load...full bar on screen...nothing else happens...MacBook just shuts down??? Please help. Can't remove Norton from drive either.

Try booting in single user mode.

If I were you, once I was there I'd uninstall the Norton stuff. All it's going to do is slow you down. You don't need the anti virus stuff on a Mac.

MacBook pro, will not start up- drive begins

MacBook pro, will not start up- drive begins?

OK, then try this:
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.
Since you can boot into safe mode successfully, I'm assuming the problem may be with a bad third-party extension or plug-in (such as a driver for third-party hardware or a bad Flash plug-in, for example.) It can also be a problem with a bad cache or preference file. If the above doesn't help then use a utility like Lion Cache Cleaner 6.0.5, Cocktail, TinkerTool Sys..., or OnyX to clean out user, system, and font caches.

My MacBook Pro will not start. When I started it goes to a gray screen with the Apple logo and has the spinning dial. When I started in safe mode it will not start. In safe mode it as an error message that says MacBook Launch_msg():Socket is not connected

If running 10.7 or later hold down Command-R at Startup.
This should invoke recovery Mode.
Choose Disk Utility.
Select your Hard drive. Inspect the SMART Status in the lower right of the window for "Verified".
Select the Mac OS X Volume (originally Macintosh HD) click (Repair Disk)
If errors, run again until it comes clean or gets stuck.
Report any error messages.

MacBook pro will not boot. I get the gray screen, an apple icon and spinning wheel. Tried to start in safe mode but get the same screen. The only thing different was that I loaded the zedge sync app yesterday. Now getting this problem.

Macbook pro will not boot. I get the gray screen, an apple icon and spinning wheel. I tried to start in safe mode, but get this same screen. The only thing different is that I added the zedge update app to do a sync for adding ringtones to my apple cell phone. How can I get a good boot. I am fairly new to apple computer.

Reset PRAM: http://support.apple.com/kb/PH4405 and then try a normal boot.
Run the Startup Manager to select Startup disk: http://support.apple.com/kb/HT1310
If those did not work your disk may be sick or dying. The top priority at this point is to make a backup copy of your data.
Check the health of the disk. Boot in Recovery Mode (Boot, Command-R). Run Disk Utility. Click on the upper left disk icon. Does the S.M.A.R.T. status say “Verified”? If not the disk/SSD is unhealthy and needs to be replaced. Even if it does not show “Verified” you can still attempt a backup.
Click on the icon indented below, usually called “Macintosh HD” and Verify Disk. If it finishes with a green “OK” message then all is well with the disk. If it shows errors in red then you have found a problem to address once the system is backed up. Do not attempt software repairs until you have secured the data.
If the disk will not show up at all in Disk Utility as your ran the tests above then it may be dead or it may have a bad internal SATA cable. A trip to an Apple store for confirmation would be in order.
If you have an external disk drive you can use as a backup drive then do so. If not Google “Hitachi USB 3.0 external hard drive 1TB” to purchase one or go to a brick-and-mortar store (including an Apple store) to pickup one. Any 1 TB external drive will do.
Assuming it is still breathing you can try to recover the data without booting from the sick disk.
Reformat the external disk. (This will erase all data on the external disk.)
Boot in Recovery Mode. Start Disk Utility. Plug in the new disk. Select it’s disk Icon (the second one down, left justified). Select the Partition tab.
Partition Layout > Single Partition
Name: Emergency Recovery 1 (or whatever name you wish to use)
Format: Mac OS Extended (journaled)
Options… > GUID Partition Table > OK
Apply
Select the Restore tab.
Drag the old system volume (Macintosh HD) to Source.
Drag the new disk volume (Emergency Recovery 1) to Destination.
Click on Restore.
It may take a long time for the backup.
If that will not complete post back for other emergency data recovery methods, including those from a brody.
If the backup succeeds, use the First Aid tab in Disk Utility to select the old volume (Macintosh HD) and Repair Disk. If it does not finish with a green OK message try to repair it once or twice more. If it repairs with a green OK message, will it boot normally? If not, boot from the Recovery Partition and reinstall OS X.
If it is still not healthy, post back for further instructions.

My MacBook Pro will not start up after entering correct password.

My MacBook Pro will not start up after entering password. Circle with an X in it and 'cancel' below it is on bottom of screen. When clicking on cancel, nothing happens. This just started last night.

Hi MJTOOTS,
Since you are getting to the login screen, it is booting past the "gray screen" phase, so try the steps in this article, like a Safe Boot.
Resolve startup issues and perform disk maintenance with Disk Utility and fsck

You may also want to see if any of your Login Items are causing an issue.

My macbook pro will not boot. It gets the grey screen with the apple until the bar is half way across and then shuts down. The only screen I can get to is in safe mode and I don't know what to do with that

Actually it sometimes gets a little further, the display will dim and the pointer will appear and then whoop it will turn off. if i do a verbose start up, it will finish all the steps, the white screen will appear and dim and then it will turn off.

My macbook pro will not start up or turn on. Any suggestions?

I had the same issue I bought my MacBook Pro in Jan. my harddrive was bad and they had to replace it. I know the guy held down the shift botton for a little then pressed the power botton while still holding down the shift botton and it turned on but not completely since my hard drive was bad.

My Macbook Pro will not charge. I have tried other charges and nothing. Can the MagSafe port go bad? Is that expensive to repair?

The port can fail. Internal boards can fail. Batteries can fail. All with the result that no charging occurs.
You can try Resetting the System Management Controller and you can try Troubleshooting MagSafe adapters.
But usually you will have to take the mac in to a service place for testing. It can get expensive, although occasionally it is not.
