Macbook Pro 17" Wont start up/ Install OS X

When I got the Mac it had the problem When I tried to boot it up it would show the apple logo, a loading bar and then it would just power off .... (Not boot up).
And when I tried to boot into recovery mode using the OS X disc and a Bootable USB I made. It would get stuck on a screen with the prohibitory symbol and would just stay like that. (http://cnet4.cbsistatic.com/hub/i/2010/01/29/e8ec4a91-fdba-11e2-8c7c-d4ae52e62bc c/96a6baa6398cfcfbbf90ea5d99e3ccf3/ProhibitorySign.png)
Took it to a local PC repair shop, but they couldn't fix it but told me the HDD was faulty/corrupt. So I bought a new HDD and installed it and when I boot it up I get the flashing folder symbol, as it is a new or blank HDD. But again when I try to install OS X using the disc i still get the prohibitory symbol
Help!!!!!
Going to college in a few weeks and really need this to be fixed A.S.A.P

It is helpful if you would indicate the exact model MBP you have.
Install the HDD in an enclosure and attach it to the MBP.
Take the original installation disk (Leopard?) and start up the MBP and install the OSX on the external HDD. Boot the MBP from the external HDD. If that is successful, it indicates the internal SATA cable is faulty and needs to be replaced.
Ciao.

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.

My MacBook pro don't start after installing Lion

Hi
I just downloaded Lion from AppStore, then my MacBook pro wan,t start. It is only the apple.

I'm afraid that with hardware problems, such as you dsecribe, are difficult (if not impossible) to diagnose over the Internet. You're just going to have to break down and make the trip to your nearest Apple Store or AASP and have them diagnose your computer. I take it that you didn't purchase the extended AppleCare Protection Plan? Let's just hope it's not a logic board problem...

Macbook Pro - Applications wont start without External Display

Hi all,
Apologies if this question has already been answered, but I have spent a lot of time Googling to no avail...
I have an early 2011 15" MBP with the following spec:
Model Name:          MacBook Pro
Model Identifier:          MacBookPro8,2
Processor Name:          Intel Core i7
Processor Speed:          2 GHz
Number of Processors:          1
Total Number of Cores:          4
L2 Cache (per Core):          256 KB
L3 Cache:          6 MB
Memory:          8 GB
Boot ROM Version:          MBP81.0047.B24
SMC Version (system):          1.69f1
AMD Radeon HD 6490M / Intel HD Graphics 3000
Snow Leopard Mac OS X 10.6.8
I normally use the MBP with a 27" Cinema Display connected (mini display port/thunderbolt connector) and the clamshell shut. All is fine.
However, if I remove the external monitor and want to use the MBP with just its own display, some applications will not start. They bounce int he dock for a while and then hang, and need to be forcibly killed. Not all applications behave this way, but so far I have experienced this with Aperture 3.2, Omnigraffle, Parallels, Pixelmator.
Does anyonw have a clue whats going on and how to fix?
Thanks

Hi Grant & Bob
Thanks for your responses.
The adaptor has been removed from the Mac, and I have tried all the obvious solutions (like using detect displays), but to no avail.
I will try and investigate some other scenarious (like using a different external display) and see what happens.
Thanks

Macbook pro 2010 wont start up?

My wife used my macbook pro in battery mode until it went flat and died on her. She plugged it in to recharge and when she tried using it again it just opened the first grey screen (with spinning wheel) and stayed like that!! Ive tried some suggested reboots to no avail and now it opens grey screen with spinning wheel and a bar apears below for a minute or so then it just closes down again. Any ideas guys??? Cheers:)

Well, I´m the geeky type of guy, so I have quite a lot of computers, so what I did is I took the hard drive out of my MacBook Pro and inserted it into a 2.5" external enclosure, then copied the files i wanted on to another computer.
Then put hard drive backing computer and insert a Mac OS 10.6.3 Snow Leopard install disk > partition the hard drive and install Snow Leopard > copy the data from the computer that you have previously copied the data on to a memory stick or a external hard drive and transfer it to your MacBook Pro
Thats what i´ve done
hope this helps!

Completely new Macbook Pro 13'' wont start!

Hey there. I'm pretty desperate now. After waiting for some time for my new(first) macbook pro, I finally received it today. My problem is now that it's stuck in the window with the Apple logo and the spinning loading wheel at the first start. What can I do? I've tried SMC, but that didn't help. Now I really hope that you guys can sort it out for me!
Thanks
The model is MBP 13.3/2.4 ordered a week ago

Started working after some tries! When i held the C-key during bootup, I got to the installer!

Macbook pro os wont start

hi
i have a macbook pro running leopard and i cannot get my os to start up. it goes to the grey apple screen wtih the wheel at the bottom then to the dark grey restart screen. ive never had this problem before. any ideas?!...

Welcome to Apple Discussions!
This is usually a kernel panic issue*:
http://www.macmaps.com/kernelpanic.html
I suggest first off telling us the state of your backup, and if there is none, look into data recovery options*:
http://www.macmaps.com/backup.html#RECOVER
Once your data is safe, we can discuss further options.

Mu macbook pro 2012 wont start it goes into this i cant get anything help please

my macbook pro is only on safe mode, was working fine then plugged in battery charger and it came up with a funny screen and voice asking what language i wanted i did disc repair but it said it didnt need it all i can get into is the help line PLEASE HELP

Adam,
if preserving your files is worth your effort, then copy them to an external drive; if not, then don’t. Once you’ve preserved whatever you care to, go back into Disk Utility from Recovery mode, select your internal disk from the left-hand side of the window (probably the first item in the list), and select the Erase tab on the right-hand side. In the Format dropdown, select “Mac OS X Extended (Journaled)”; in the Name textbox, enter the name for your reformatted volume (“Macintosh HD” is typical); and then press the Erase… button. Once the erasure is completed, exit Disk Utility, and then select Shut Down from the Apple menu. When you power it up, OS X Internet Recovery will download your MacBook Pro’s original version of OS X from Apple’s servers, and then reïnstall it. When it restarts after the installation, run Software Update to bring it up-to-date, and then copy your preserved files back to your internal disk.

MacBook Pro won't start after installing new hard drive and me

I changed the hard drive and also upgraded the memory on a mid 2010 13 inch Mac and then used the disks that came with it to reinstall the OS that came on that disk. It worked fine and installed and then the screen came on to transfer from the time machine to the new hard drive so I said yes, and it seems to work fine but then when it finished it asked me for a password. I hadn't put a password on it so that was a surprise. I tried several things but it finally only had the option to restart and when I did that it seemed like it was starting with the apple symbol and the little gear but then it went to a Gray screen with the little gear, and then seems to freeze and then finally goes to the blue screen. The disk to reinstall is still in the drive but I can't seem to get the install to start again. I've tried holding down the c key and starting, I've tried holding down the command plus the c key and nothing....just goes to the blue screen. Any ideas on how to fix this?
Thanks

Hi,
Before trying the following, make sure you can still read the 25 Character Product Activation key on your Windows COA label ( 5 blocks of 5 alpha/numeric sets ).
Assuming that this is just a problem with the Recovery process, there is a straight forward work around if you have ( or can borrow ) a retail Windows 7 installation disc that is exactly the same version as your OEM installation - ie if your notebook came with Windows 7 Home Premium 64bit this is the exact retail version you would need.
If you don't have access to a retail disc, you can create an installation disc yourself using another PC - just download the correct Disc Image from the link below and use an application such as ImgBurn to burn the ISO correctly to a blank DVD - a guide on using ImgBurn to write an ISO to a disc is Here. These Images are clean and from a well-respected source, however there are only limited versions available.
Windows-7 sp1-iso-official-32-bit-and-64-bit
Use the disc to perform the installation, enter the Windows activation key found on the COA Label when requested and when the installation has completed, use the 'Phone Method' detailed in the link below to activate the OS - this method supported by Microsoft and is popular with people who just want a clean installation of Windows 7 without the additional software load normally bundled with OEM installations.

Macbook Pro just wont start?

Ive had my MBP for little over a week and everything was working fine. A few days ago I tried turning it on and the LED light on the button that flips the screen up came on, I could hear everything inside spinning around and whatever so that all seemed fine but I couldnt hear any sounds that you normally hear when you turn it on (Like that big DUMMM when the apple logo appears) and the screen just stays black. So its as though ti starts, but just before the screens about to turn on, everything stops. The usual reaction kicked in, i s* myself! Considering this MBP was bought for me for my course and it needs to be handed in at the end so it is not technically mine. I held the power button and turned it off, pressed the power button and turned it on again and it worked. So i didnt think much of it. Then it became more frequent and last night I was on safari and safari just crashed, i tried force quit and then my MBP just switched off. I tried to turn it on and the same thing happened, only it hasnt switched back on no matter how hard I try. Its been broke since last night and I need it preferably for tommorow morning.
Ive looked and there seems to be similar problems, but they all get solutions like Hold the power button, hold cntl, cmd, p and r and whatever but that doesnt help me. Nothing happens!
Also I placed a DVD in my MBP to check if the optical drive was working fne and it succesfully swalloed it without giving it back and now I dont know how to get that out. Ive tried turning it on and holding the mouse button (even though its a trackpad) and nothing works.
HELPPPP?!
Would anybody reccomend the genius bar? Plus does it cost? Do I need proof the MBP is mine because all the documents are at the place where I take my course.

I dont have the installer disk, its all at where I do my course... The only thing I have is my laptop and power lead. I was hoping I could et it fixed myself so its like it never happened and it can be forgotton about. Sounds a bit wierd but you know... Saves the ear ache.
And i meant does the genius bar cost? Sorry for the inconvenience. (Spelling :S)
EDIT: The cmd, option o and f keys dont work.

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.

Installed Yosemite...now my MacBook pro won't start up. Keep showing "Kernel Panic!" HELP!

installed Yosemite and now my MacBook pro won't start up. Keeps showing "kernel panic"
PLEASE HELP ME!

If you can't start up and log in in the usual way, try in safe mode.
During startup, you’ll see a progress bar, and then the login screen, which appears even if you normally 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.
Log in as an administrator to carry out these instructions. If you have only one account, you are the administrator.
☞ If you don't see any reports listed, but you know there was a panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
Safe mode is slower than normal, and some things won’t work at all.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t start in safe mode.
If you're able to log in, launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
In the Console window, select
DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar.
There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of reports. A panic report has a name that begins with "Kernel" and ends in ".panic". Select the most recent one. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
I know the report is long, maybe several hundred lines. Please post all of it anyway.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
Please don’t post other kinds of diagnostic report.

I was messing around with .kext files in the MacintoshHD and now my MacBook Pro won't start up.

I was messing around with .kext files in the MacintoshHD and moved the system.kext and two others to my desktop and deleted the originals and now the MacBook Pro won't start up. All I get at start up is the apple icon then a bunch of text shows up part of which says Mac OS version: not yet set. then the apple icon turns into the power icon and tells me to turn off the computer. I've tried reinstalling from the install DVD by holding down option when powering on and selecting the install DVD and it just goes to a white screen with the apple icon and stays like that. I didn't have the disk utility on my Mac before this happened because I deleted it to make room on my computer a while ago so I'm not sure if that's why it won't load the install DVD but anyone who knows the solution to this with out going to get it repaired would be greatly appreciated. Thank you!

Never mind my dad just found the original install DVD and that worked. Before I was using an install disc that Apple sent me for another issue I was having, but thanks for replying so quickly and trying to help on this Thanksgiving day!!!

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.

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.
