MacBook pro won't start up after I tried latest upgrade, 10.7.3

I can't get MacBook pro to start. Stuck with spinning wheel. I have tried safe mode boot and it will not even recognize. Any ideas?

I'll assume you have backups of all your data. If that assumption is wrong, don't follow this suggestion. Boot from your recovery partition (command-R at startup) and reinstall Lion. You don't need to erase the boot volume, and you won't need your backup unless something goes wrong. If your Mac didn’t ship with Lion, you’ll need the Apple ID and password you used to upgrade.

Macbook Pro won't start up after removing and putting back battery

One week ago I spilled two drops (literally) of water on the drag pad of my MacBook Pro (model A1278). Some of this water went down the top edge of the drag pad. Since this happened, the cursor as either not been been responding at all to my drag pad, or it has been behaving very eratically, as well as this, over the last couple of months since buying this MacBook, there has been an abnormal amount of dust in the air in the house due to some building work going on here. This being so, I decided to follow a video tutorial in you tube on how to remove and clean the drag pad. This involved getting access to the laptop by unscrewing the back, unscrewing and disconnecting the battery, then unscrewing and disconnecting the drag pad, so this it could be handled and cleaned. I followed the video to the letter, taking great care. I cleaned the drag pad as instructed, and replaced it. I did the same thing with the battery. All screws and the two simple 'plug in' connections for both the drag pad and battery have been replaced smoothly and exactly as I found them. but after putting the back panel on the MacBook, it will not turn on. It will not power up, either by the battery alone, or by using the mains power lead. There is a green light showing on the power lead input, but it is nowhere near as bright as it usually is. So I have gone from having a poorly functioning drag pad, to now having a MacBook Pro which won't even turn on! I have no idea what has happened. Please can anyone help? Thanks.

So are you saying that it will not boot from the OSX installation disk?
It might be worth trying an SMC reset as described here:

'09 MacBook Pro won't start up after installing new hard drive and restoring from an external hard drive.

I am in the process of replacing my hard drive and have run into a problem. I reinstalled OSX 10.6.3 using a DVD I bought off Amazon. That went well and I then restored my hard drive using an external and Time Machine.
After that, things still looked good but I couldn't log in to my user (and access my MacBook) because my password wasn't working even though my hint was correct. Yes, I am POSITIVE my password was correct; I even tried a couple other passwords to humor myself. I then gave up and decided to restart the computer.
Now my MacBook won't start up at all. It goes o a gray screen with a still loading symbol for a couple minutes and then goes to a solid light blue screen. I've tried starting up while holding command+R and I tied holding just command and neither worked.
Did I install the wrong OSX because I didn't use the same DVD that came with the laptop? Is there something wrong with my hard drive already?
Please help =[

You probably bought the wrong RAM that has different pin assignments, so it won't fit in the slot. Return it.
I bought 4GB Memory online for my MacBook, so I could get it to run twice as fast.
Doubling the memory does not make your computer run twice as fast.

MacBook Pro Won't Start up after leopard Install

I installed leopard on my MacBook Pro 2.0 GHz Intel Core Duo. Well at the end during the restarting phase it took forever to restart and my power was running out so not sure if it restarted or batt went dead. After recharging i turned on mac and wont boot up past the apple with dots hovering it. Don't know much about macs so if you could help it would be appreciated.

Welcome to the Apple boards:
You installed Leopard on battery power? That's a real big no no. A very risky gamble at best.
If your battery died during install, you may well have totally hosed the system.
After recharging i turned on mac and wont boot up past the apple with dots hovering it. Don't know much about macs so if you could help it would be appreciated.
See if you can boot into the Leopard DVD (hold down "C" on boot) and after the language screen, on the top left will be a menu. Select Utilities, run Disk Utility and repair your HD and permissions.
See if that gets you somewhere.

MacBook Pro Won't Start Up after USB power draw...

My WD external drive was connected to my MacBook Pro while operating from battery. An onscreen message appeared about drawing power from the USB device and the computer shut down, now it won't restart. The power adapter won't even light up when I attach it. HELP! Its a 2010 MacBook Pro.

Try and reset the systems power management. First disconnect the power adapter then hold down then the next step all has to be done in one sequence. You will need to hold down three keys on keyboard on left side they are shift key, fn key and ctrl key while pushing down the power key hold them all down for 3-5 seconds then let up on all keys and push the power button immediately.
Also you might check the power adapter if you have the square one that you can remove the duckbill then do that while to adapter is unplugged from power source ie wall socket as well as the computer.

My macbook pro won't start up after updating it

I Have a macbook pro with Mavericks (I don't remember exactly which one) which I bought in 2012, yesterday night I updated it and it restarted but it took forever and I thought it was installing something, so I left it like that all night and day and is still in the gray screen with the apple logo and the wait spiral. I got worried so I entered the disk utility option and checked the disk, and it said everything was Ok. When I restarted it again, the gray screen never left so I tried with the "safe rebooting" ctrl + cmnd + V and the screen shows now endless rows of "disk0s2: 1/0 error." and it's been like this for about half an hour now, I'm really worried I'll my data.

An 1/O error cannot be repaired by Disk Utiity.
That requires a more robust disk utility such as DiskWarrior
You can contact the developer using their email address here.
Best to get their recommendation before purchasing.
Hopefully you have a backup to restore from once the drive is either repaired or replaced.

MacBook Pro won't start up after update

I just updated my MacBook last night and now when I turn it on it gets to the grey apple screen and shuts down.

Reset PRAM: http://support.apple.com/kb/PH4405
Try a normal boot.
Perform a Safe Boot: http://support.apple.com/kb/PH14204?viewlocale=en_US
Try a normal boot. If it boots reliably with a Safe Boot but not a normal boot then it is probably a software issue. Post back for more instructions.
If you do not have a recent backup create one in case your disk is failing. (Post back if you need instructions on how to do that w/o booting OS X.)
Boot in Recovery Mode. (Hold down the Command (⌘) and R keys as your computer restarts. If you are running 10.6 or earlier boot from an installation disk.) Run Disk Utility. Click on the upper left system disk icon. Does S.M.A.R.T. report “Verified”?
If it does not say “Verified” then the disk or the disk cable is failing and will need to be replaced. As noted above, if it is failing the first priority is to back it up. Post back for more instructions for emergency data recovery and replacing the disk or its cable.
If the S.M.A.R.T. status is “Verified” then repair the disk. Click on the icon underneath and indented to the right, usually called “Macintosh HD”. Repair Disk. It should finish normally with a green OK message. If it does not try to repair it again.
If it will not finish with a green OK message then having a backup is again essential. The remedy is a clean install: backup, reformat the drive (erasing all the data), reinstall OS X, and then restore form the backup. (Post back if you need instructions on how to do any of those steps.)
If it repaired all errors (green OK) and is still not booting normally “Macintosh HD” icon again and Repair Permissions. Ignore the numerous messages in black. It should finish with a green OK message. If not, run it again.
Once you have repaired the disk and the disk permissions, if it will not boot properly, reinstall OS X:
Boot in Recovery Mode and then install OS X.
If it is still not booting normally after the reinstall then, as a last resort, perform a clean install. Make sure you have a current backup (Time Machine or a clone). Boot in Recovery Mode. Use disk utility to erase the system disk (deleting all data). In the Erase tab click on Security Options… Select “writes a single pass of zeros.” This will write to every block on the disk, mapping out bad blocks. Install OS X. Reload your data from the backup. (On the first boot the Migration Assistant should as you to restore from your backup.)

MacBook Pro won't start up after PRAM restart and a control/command restart

My iPhone 4 froze up and I tried to sync and restore the iPhone software. This made my iTunes prompt me to restart my Mac. Now it will not start up. It stops after the chime and grey screen comes on. I have tried a PRAM restart with no luck. Can anyone help?

So are you saying that it will not boot from the OSX installation disk?

My MacBook Pro Won't Start and I've tried all of the suggestions I can find to no avail. What should I try?

When I boot the computer I get the flashing question mark. I have tried:
1.) Holding 'C' to access the 'Startup Utility' but the only thing that accesses is the Wireless Internet access.
2.) Holding [cntrl. option, power button] but that didn't access anything
3.) Holding [shift] to access safe mode, but that didn't access anything
It also suggested loading the 'startup disk' that came with the laptop, but I'm digging through the box and I don't seem to have one.
I don't seem to have access to removing the battery (I, at least, don't see the battery and would have to take the thing apart to access it)
The problem started with a stuttering/ skipping of the functions a couple of days ago- of which I started this thread: https://discussions.apple.com/message/17083016#17083016
That seemed to solve the issues until this morning when a video I was playing suddenly froze. I restarted the computer and the flashing question mark appeared.
Can anyone help with this please?

A flashing question mark appears when you start your Mac
Holding 'C' to access the 'Startup Utility' but the only thing that accesses is the Wireless Internet access.
You hold the C key down when booting from your install disc. Hold down the Option key to prompt the Startup Manager window where you can select the startup disk. If the startup disk is not available from that window then it's likely failing or has failed.
Holding [cntrl. option, power button] but that didn't access anything
Just the Option key.
It also suggested loading the 'startup disk' that came with the laptop, but I'm digging through the box and I don't seem to have one.
It's an "install" disc, not startup disc and you need those discs to repair your Mac or take it to an Apple store or Apple certified repair shop, Since you don't have those discs and you can't boot in Safe Mode (Shift key) you have no way to verify the disk.
Replacement disc(s) from Apple: You can get replacement System Install & Restore CD/DVDs from Apple's Customer Support - in the US, (800) 767-2775 - for a nominal S&H fee. You'll need to have the model and/or serial number of your Mac available.
And hopefully you removed all vestiges of MacKeeper.

MacBook Pro won't start after changing access rights

I did something very wrong. Unfortunately I changed the access rights of Macintosh HD for "everyone" to none.
Result, my MacBook Pro won't start anymore.
Already tried the installation disk, reset password for root and users. No result.
Help program "check acces rigths". Didn't work either.
How do I reset the access rights of Macintosh HD?

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.

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.

Macbook Pro won't start properly... keeps restarting without chime!

Macbook Pro won't start properly... keeps restarting without chime!
Late 2007 Macbook pro. OS upgrade worked great for me.
I have had this problem on and off for a month or so. I simply cannot figure out what the issue is. I have tried poerup with and without AC power and with/without battery installed.
Starting in Safe mode does not help.
Trying to start with a disk does not help.
It sort of seems like it might be an internal power issue or GPU issue.
It also feels sort of like a software compatibility issue since my Macbook Pro gets reallly slugish for no apparent reason sometimes and IU have to restart.
I have three different anti-virus programs so I doubt it is a virus issue.
I noticed all this start after I did a Mountain Lion upgrade and then tried to start up VMware Fusion. Fusion seemed to just bog down the computer horribly but did not cause a system crash.
I need to edit an important sequence on Final Cut Pro and don't want it to freeze me out!
Anyone who has had this problem and resolved it please let me know
God bless

If it doesnt chine it doesn't mean much, the mute could be on or you installed a anti-chime software.
