MacBook Pro 7,1 won't boot Mac OS X Install DVD

I recently replaced the standard hard drive that came with my MacBook Pro 7,1 with a SSD and when I try to install the original Mac OS X Install DVD (version 10.6.3) that came with the computer, the drives spins up, and the grey screen with the spinning city circle comes up and the spinning circle eventually freezes and doesn't work past that point (waited at least 30 mins) minus a hard shutdown.
I have reset the SMC, zapped the Pram, tried doing an online install from disk 2, ran the apple hardware test (no problems) held down the option key and booted to the disk from there! Nothing works (and I have installed OS X from a clean SSD on other computers.
Please help!!
Thanks!!!

Did you prepare the new SSD?
Drive Partition and Format
1. 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.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
Now try installing Snow Leopard.

Mac Pro 12-core won't boot Mac OS X 10.6 "Server" Install DVD

I have just received my new Mac Pro 12-core today.
I tried to boot from my Mac OS X Server (10.6) Install DVD with no success.
I WAS able to "upgrade" from the preinstalled Mac OS X 10.6.4, but I need a clean installation.
I first thought there was a problem with the internal DVD drive, but I could boot the provided Mac OS X Install DVD. I also tried to boot the "Server" DVD from a firewire external DVD drive, with no success. I even tried "target" mode, using the DVD drive from a Mac Book Pro, with no success.
The server install DVD is not corrupted, as I used it recently on my 2007 Mac Pro 8-core.
Please help.

My Macbook Pro (early 2008) won't boot, then booted, now won't boot again.

Hey all,
Summary:
My GF's Macbook Pro (Early 2008, non-unibody I believe) "died" earlier this year without notice or a cause for why, then it worked months later, then it didn't again.
Symptoms:
It stopped booting, with the only signs of life are:
The annoying boot sound that you hear right-away, like a winding sound. "Weeeeah woooo"
A fan turns on immediately after the sound.
The front light (on the open button) is solid.
The battery will light up and show how much juice is left.
The only thing to do from here is to hold down the power for 10 seconds.
Don't worry, my story gets more interesting...
Now, I had another computer and my GF didn't need her macbook seriously for a while, so I didn't research the problem or how to fix it, until last week. Perusing the various help forums and communities, I came across the reset SMC suggestion, so I decided to try a few things on Apple's SMC reset page.
I tried a couple things, including taking the battery out, and LOW AND BEHOLD: IT CAME ON, like nothing happened! The screen was fine, the performance was fine, it updated (to the new Safari and iTunes, as an example) fine, and it restarted fine multiple times. One of the main reasons I wanted to get it working was to save some family pictures we had saved, so I started uploading the images to an image cloud site. I'm sending them at full-res so it takes a while and I go to sleep around 2 am so I'm not too late into the office in the morn. When I wake up, I go to check the image upload progress and the laptop is Off. I figure it just went into standby after finishing, so I hit the power button...
And it doesn't boot again. It's back to the same issue as before. I try doing what I did last time, then resetting the SMC, but nothing has worked this time.
Any ideas? It's out of warranty of course, which is why I'm here.
Thanks in advance!

Since no one else is answering, I’ll jump in.
Your story is interesting indeed. I’m not sure I can help you fix the Mac but it sounds like there is a reasonable chance of recovering the data.
I assume it came with installation disks. Will it boot from them? If so run Disk Utility from there and try to repair the system disk.
For the hardware problems on your Mac it is time to take it to Genius Bar at an Apple store for a free diagnosis and estimate of repairs.
Genius reservation http://www.apple.com/retail/geniusbar/ .
It could be your disk failing but it sounds more like flakey electronics in the system. Let’s assume is is the system board until a Genius tells you otherwise. If so, you can simply put the working system disk in an external enclosure, mount that on your other Mac and copy the data. Here is a source for the inexpensive hardware you would need:
Toolkit: http://eshop.macsales.com/item/OWC/TOOLKITMHD/
SATA enclosure: http://eshop.macsales.com/item/OWC/ES2.5BPU2W/
There are multiple directions to go from here. Let me know what happens when you try theses first options.

MacBook Pro HD issues; won't boot to any drive; need to recover data

*Apologies in advance for the lengthy post. I just want to be sure I include as much detail as possible. Thanks in advance for reading all of this and offering any thoughts and suggestions.
I have a 13-inch late 2011 MacBook Pro running OS 10.7.
The computer recently began booting slower and slower until finally one day it did nothing but show the gray boot screen with the apple and a spinning circle and/or progress bar at the bottom. It won't do anything else. I assume it's the HD; no surprise there. What's killing me is that no matter what I do, I can't boot to any disk, internal or external, can't mount it in target disk mode, and can't repair it or recover data, which is a first for me with any HD. However, the computer still clearly sees the drive, and the drive sounds and runs normally (meaning no clicks; appropriate amount of whirs and such).
What I've done so far:
Reset PRAM — no help
Reset SMC — no help
Boot in Safe Mode — same result as regular boot: gray logo screen with spinning wheel
Disk Utility message:
Verify Disk — "Error: This disk nees to be repaired. Click Repair Disk."
Repair Disk — gets as far as "Checking catalog file" then shows "Keys out of order". Next is "Rebuilding catalog B-tree." Then "The volume Macintosh HD could not be repaired."
fsck — same as Disk Utility: "Keys out of order (4, 22016)", "Rebuilding catalog B-tree", then "The volume Macintosh HD could not be repaired." FILE SYSTEM WAS MODIFIED." ...over and over again
If I hold Option while starting the computer, it gives me only two drives to boot from, regardless of any other external HDs or flash drives I have attached: Macintosh HD (internal), and Recovery HD (internal partition). If I choose Macintosh HD, it's hit or miss whether it prompts the Disk Utility screen or just gray-screens forever. If I choose Recovery HD, it successfully runs Disk Utility every time. Here's the thing, though — if I attach an external HD, it doesn't see it during the initial Option-startup. However, from Disk Utility I'm able to select a startup disk from the menu to restart into. It sees the externals in there every time and lets me select them as startup disks, but upon restart it returns to the gray Apple logo screen with spinning wheel and/or progress bar at bottom. Sometimes it also sees the internal Macintosh HD here, but selecting that is useless. I can't actually boot from any disk, internal or external, running full OS or even just recovery software.
I've tried using TechTool Pro 8's edisk and ProToGo bootable drives, but again, the MacBook only sees them from Disk Utility only (not on Option-start), and I can select them, but it doesn't actually boot to them; it reverts back to gray screen.
I've installed a full version of OS 10.10.2 on an external hard drive, complete with DiskWarrior 4 on it, but same problem as above — it sees it in the "Select Startup Disk" menu, but not in the initial Option-start or successful reboot.
I've tried booting from a DiskWarrior 4 DVD using C-startup. It recognizes and spins the DVD from the get-go. Eventually it boots to it (after about 20 minutes or so of reading the DVD). I'm able to launch DiskWarrior 4 and start a rebuild. However, it goes all the way through "Step 6: Constructing optimized replacement directory... Overlapped files detected: 7 ...Step 7: Finishing construction ...Step 8: Reading from disc, one moment please..." and then the computer kernel panicked. This happened several times. I reset the PRAM again, then retried DiskWarrior DVD boot, this avoided a kernel panic and it got as far as "Comparing directories... Step 9: Recording any file or folder differences; 3,449,089,956 tests..." and then DiskWarrior and the computer both freeze and I have to force shutdown.
The drive will not mount to another laptop in Target Disk Mode.
Disk Arbitrator immediately sees the the faulty laptop HD, but won't let me mount or unmount it. It's just there, grayed out.
Data Rescue 4 is able to see the faulty laptop HD through Target Disk Mode, even though the drive itself will not mount to my desktop. I am able to scan the drive using DR4, and start a data recovery process. However, DR4 is dumping all recovered data into "User Defined" ai (Adobe Illustrator) files, which makes absolutely no sense at all. What's more, the files aren't able to be opened by any program. Even files that it hasn't recovered into ai files, like txt and mpegs, cannot be opened. I've tried recovering from both the drive itself and from a clone of the drive (made through DR4), with the same result each time.
So, all of that said, I guess my first question is what the **** is going on? The drive mechanically is functioning fine, but there seems to be an issue with its readability (and the directory/files?).
What's more, why won't this laptop mount ANY drive? I should be able to Option-boot into any drive, especially if the USB ports, drives, and OS's are all fully functional, right? Is there any workaround I'm missing? Even if the internal drive and data are just screwed, what's causing a total lack of mounting or booting of any drive, internal or external?

Holy crap, I got it to work.
Essentially, I just waited until DiskWarrior reached Step 9 and told it to skip the step before it had a chance to freeze. It skipped successfully, moved on, rebuilt and replaced the faulty directory files.
So far the computer is booting like normal, I can log in, and I'm currently copying all of the data to an external as I type this.
I still have no idea why the computer wouldn't mount or boot to any drive, but I guess I'll deal with that later.

MacBook Pro mid 2009 won't boot OSX

Since today i have a strange problem booting into Mac. This is how it started out:
I was inside of Mac, and decided to reboot to Windows, to play a match of MW2. I forgot to use the ALT button, so Mac was already booting. I used the on/off switch to turn it off before i started it again. This time i did use the ALT button, and i booted into Windows. I decided later on to boot back to OSX, and it didn't give me any problems.
I wanted to mount a DVD ISO file to watch, and when i mounted it my user account got logged off. I logged back in and tried it again, same problem.
I decided to reboot the system, but this time something wierd happend. Along with the Apple logo i got a grey progress bar, wich went till about 25%. After this bar dissapeared it was just the Apple logo with the rotating gear, and it didn't go any further.
I tried using the installdisk to repair my OSX partition, but whenever i try to repair i get the following:
Repairing volume completed.
Updating startup support partitions where necessary.
Error: Diskaid cannot repair this disk
(original messages were in dutch, so in translated it. Could be different from the english messages)
Diskaid also shows my OSX partition as grey, instead of the normal black. I can't seem to be able to activate tis volume in Diskaid
After this i tried running Apple Hardware Test, and it didn't give me any errors.
The strange thing is that Windows(bootcamp ofcourse) runs fine. It's Mac OSX that cannot boot.
I don't have backups, and no Time Machine either. Is there a way to get my OSX back up again without having to reinstall everything? Especially because of certain installed Audio Units. I don't have the original license codes anymore of same AU's, so it would be a real pain if i need to reinstall this again.
I'm using this mac:
MacBook Pro 15"2,66GHz mid 2009
500GB 7200RPM Hard Disk
Hope you can help, i really need this one to be back up as soon as possible!
Thanks in advance!

Your options are:
1. DiskWarrior to rebuild the directory. Or,
2. Erase & Install

Macbook pro (early 2011) won't boot after sleep. Black screen with chime

I put my macbook pro early 2011 (Quad, 8 Gb RAM, 2 x SSD-disks, external 27" LED-screen) into sleep mode a couple of days ago. Everything was fine then.
However, the morning after it wouldn't wake up - this is the bootup process:
- Black screen
- Chime
- Still black screen, nothing happens.
So I've tried resetting NVRAM, SMC etc - no luck. Even tried the "Powerbutton" + "S" + Enter but to no avail.So I immediately began dd:ing my SSD-disk before trying anything else, figured it might be some preboot-corruption of some sort since I'm running FileVault2 with full AES-encryption.
Now, the problem (after some troubleshooting) doesn't seem to be disk-oriented. Remember the black screen? I've tried pulling the SATA-cables one by one on the motherboard of the Macbook pro and discovered that when I pulled the cable which reaches over the optical device (just above the SATA-cable for the optical device) then I get a white screen and I'm able to get as far as boot-option, or even disk repair (if I run my SSD-disk over USB and without any cables (three of them) attacked to the motherboard).
So since nothing works when I have disks connected or that third cable (some kind of logic board bridge? Reaches through the screen over to the other side of the mother board).
Also worth noting is that I was running out of free disk-space on my system disk. The disk is 250 Gb and free space was about 5-10 Gb (less than 5%). I also make the macbook pro dump contents of memory to disk (since my disk is encrypted it resides safely there).
So, my fear is that Apple hasn't used A-grade controllers for the disk drives (I've had drive corruption before, a Crucial 6 GB/s drive trashed less than a week before a presentation) and doesn't handle "unexpected events" nor signal/noise ratio very well. Maybe free space on disk was less than the 8 Gb needed to dump RAM (shouldn't have needed the full 8 Gb though) and this caused some kind of panic overwrite which trashed the controller?
Anyways, I've attached an image of the motherboard and I am wondering - what does the top cable which reaches over the optical drive do? Is it connected to the logic-board?

** The volume Macintosh HD could not be repaired.
Looks to me like a fatal error on the hard disk. IMHO, the only solution is to boot from an external device, reformat the hard drive, and restore from backup. If you don't have a backup, you're in trouble. Boot from the external device, try to mount the int'l drive, and, if successful, back up as much as possible. Also, try running Disk Utility—it may be possible to fix it while booted from a different device, thought I wouldn't bank on it. At any rate, make sure to run an AHT afterwards, to check for possible hardware issues with the drive.
If the machine is still covered by AppleCare, take it to the store by all means. But they won't try to recover anything from the int'l drive, just check it, erase it if they don't find hardware issues, and re-install a fresh copy of the OS.
That's why you should always have at least 1 up-to-date backup (2, with one kept off-site, is better).

2007 macbook pro keeps restarting won't boot up

Hello,
I have a fairly old MAcbook Pro (2007). Recently, after rrsinsatlling and erasing the hard drive, my MBP will not Boot up. Ive tried Resetting PRAM, SMC, etc. The symptoms are as follows.
the chime then apple logo---then it RESTARTS. I can't open in safe, or verbose, or run Apple hardware test. since it just restarts. I can't boot from DVD or External Flash drive because it just restarts after selecting the alternate startups. I also can not boot from the recovery HD because it just restarts. the only thing that delays the restart is if I don't select a startup disk after holding the option button. or if i hold the N key...at which point after about a minute or so of searching for a network disk it restarts. when i hold down the V i would see a few lines of code and it then restarts. It will continue to restart for hours until I disconnect the power adapter. (finally there is no battery in the device and hasn't had once for over 3 years when it exploded. Please help
Thank you.

I also have a Late 2007 MBP 15" that, after 5.5 years, finally succumbed to the Nvidea curse. Nvidea sold Apple a lot of video chipsets (yes, if you have a 2007 MBP, you could have the Nvidea curse) that were faulty and would fail with heat. Mine failed during a software update too.
Aple had a repair extension program for this but it expired in December 2012.
I called around a lot, finally calling Cupertino to be told the 2007 MBP not longer qualifes for a flat-rate repair due to a lack of parts.
My point is you may not be able to get the flat-rate repair. I replaced mine with a refurb entry-level 13-inch MBP that nearly twice as fast, has over 4X the hard drive space, and cost half of what the old MBP did. That was after getting several estimates for a new logic board from third-party service centers that where in the US$500-900 range. I paid US$1020 for the refurb 13-incher.

OS X Won't Boot, Can't Load Install DVD

For the last couple of days my mac has been really buggy, hanging, slow boot speed etc.
Until finally yesterday it simply failed to load into OS X.
So I tried the trusted unplug it for a few minutes, I zapped the PRAM, I tried safe mode, I did a hardware test on startup and that was fine. I've tried booting into the install DVD using 'C' and by using Options and selecting it on boot up menu. Sometimes it has limped into the OS where I removed everything in startup, repaired permissions and tried to verify the hard disk, where it said there was an error. I tried to get the install dvd to restart the computer and get into Time Machine but that just hangs, any ideas? I have a fairly recent backup, does Time Machine backup ALL my stuff? Music, Mail personal documents etc?
Cheers
A now bald Tristan

If Disk Utility has told you there are problems with the drive, you must repair them. You didn't mention trying that, you just said you tried to use Time Machine while booted from the install disk. Try booting from the install disk, running Disk Utility from there and clicking the Repair Disk button.
If the disk can't be repaired, you can try a more powerful utility, like [DiskWarrior|http://www.alsoft.com/DiskWarrior/index.html] or [TechTool Pro|http://www.micromat.com>. If those don't work, you'll have to just erase the hard drive and reinstall the system from scratch (or restore from a backup).
Note that, even if you repair the problems, files have probably already become corrupt, thus causing the problems you've been experiencing. You may end up having to reinstall anyway, even if repairs are successful, and it would be wise to be cautious with backups, as corruption could have crept into them.

MacBook Pro 2011 15" won't boot - ML

Hi,
Over the past few weeks I've bene experiencing problems with my 2011 15" MBP.
Initially, I though they were s/w related, but am no longer certain ... and was wondering if anyone has had a similar experience?? Here's what's been happening:
* about a month ago my machine started to run really slowly. It didn't freeze, but would run incredibly slowly. After reading the forums, I found some info RE apple mail and vacuuming the mail file and a few other housecleaning suggestions which claimed to help. I did these and it seemed that things went back to normal, particularly after deleting the index file in mail.
* Alas, the problem crept back after about a week. This time my machine came close to unresponsive, so I decided to reboot. Upon doing this, I couldn't get into the OS ... the grey apple logo appeared on start-up, then a white indicator bar, then it would just shut down. I tried booting into the recovery mode and using disk utility to check permissions. There were heaps of errors. I realised that fixing permissions can sometimes do harm, but had a complete TM backup so I wasn't too stressed. The repaair perimissions failed. I then did a verify disk and this too failed. Hmm.
* Now I thought that the HDD may be bad, or that the OS had become corrupted, so I decided to do a clean install of ML. This worked ... and all was well ... I made sure to check permissions and the disk in disk utility a few times and it said all was perfect.
* I managed to load my apps and data/files from TM backup. But, the day that I did a restore of my iphoto library (220Gb), the machine started running slow again. I noticed that a few times it seemd to be stuck indexing the HDD. Odd. It never got passed 'calculating the time'. I rebooted a couple of times, then was back to the unable to start scenario.
* Once again, I went into recovery mode, disk utilities and found heaps of disk permission errors. This time the option to fix was avail, so I 'fixed them'. After rebooting back into recovery mode and trying this again, more permission errors were found, but the option to fix them was now greyed out. I also tried to verify the disk and this failed - indicating HDD issues.
* My second last step was to go into terminal and try /sbin/fsck -yf to check the HDD. The HDD passed all tests and reported back that it was fine. Hmm?
* Finally I tried booting into my Windows 7 partition and that worked fine. I was also able to see the data in the OS X partition - but have't tried doing anything with it (yet).
Before I run off ad replace the HDD, or freak out that maybe something more sinister is damaged ... I hope someone out there could offer further troubleshooting suggestions or help? Does thid sound s/w or h/w related?
BTW, My HDD is a Toshiba MK 7559GSXF 750 Gb.
PS - My machine exhibited the exact same symptoms last year when I was running Snow Leopard. The Apple store recommended I do a clean install - which I did - and at the same time switched to ML. Since then, all was running fine for about a year!
PS - I don't have Disk Warrior ... but have had a quick look at it ... not so simple to use and wasn't sure what verison to run on Moutain Lion.
Thanks in advance ...

Hi ds store,
Thanks heaps for your help. In your suggestion, you mentioned two things:
1) Reformat the drive with a secure erase. When I did my previous (non secure) format of the drive, I made sure to check with DU that the drive was OK. After the format, it reported 'no errors' at all. I'm just wondering how the secure format will provide any additional benefit? Assuming that once that's done it will again report no errors. I guess what I am asking is, does the secure format do a more thorough scan or check as part of the process?
2) Find and replace 'corrupted' files. Yikes ... how does one do this? I've got about 700Gb of data (pics, files, work, research, etc). How could I identify possible issues?
As an aside, I have not yet performed the format b/c I reaslised that I have a few photos in my iPhoto library that didn't backup before this issue. There are about 100 recent pics that didn't make it to the TM iPhoto backup. As mentioend before, I can boot in my Win7 partition and 'see' the Mac HD, and know I can copythe files in the Master directory across (if I knew which ones they were) ... but ...
Think it would be easier to connect my iMac (running SL) to my MBP and open the iPhoto library directly on my iMac. This way I could identify the relevant pics quickly and copy them to my iMac temporarily.
However, for some reason, even though I've turned on sharing for the MacHD/...users/XX/Photos directory (while in Win7), my iMac doesn't recognise or allow me to open the iPhoto directory - is this a permission thing ... or is it b/c I am trying to look at a Mac partition 'through' the Win7 o/s?
Any advice would be great ..
Thanks in advance.

Macbook Pro internal HDD won't boot the OS, but if i use it by usb works perfect

Hi people I have this computer with the following problem: The computer will not start the hard drive if I left the drive internally .When start the machine with this hard drive internally I get the error foulder with the question mark, but the same hard drive boot the OS if I connect it by USB. I did the tests to verify the hard drive, but testing the hard drive they works perfect. I thought it was the hard drive SATA connector, but the computer recognizes it but will not let me do anything to this hard drive. The computer let me see the drive the file system and the capacity but can't do any change to the drive. This hard drive is formatted in journals file system that everything works fine when connected by usb and boot the operating system but does nothing when connected internally only appear but you can't make any changes in the hard drive. The machine does the same thing if a connect a new hard drive. Anyone have any idea what can happen to this machine?

If the drive is working properly outside the system but not inside the system then you have a bad piece of hardware inside the system.
If the drive does not work properly inside or outside the system then the drive has failed and will need to be replaced.
Need more info on your last post.
If you are booting the computer from that drive you can't make any changes to it with Disk Utility as the system is Running from it. You have to boot the system from some other drive to make changes.
What model year Mac do you have? When did you buy it?

MacBook Pro (early 2011) won't boot, sleep light comes on and fans come on high.

Just had a stick of RAM and the CPU replaced by Apple for an unrelated issue, but now this has cropped up. A little searching indicated that the GPU became unsoldered, but I'm curios if anyone can shed some light on this issue.
Thanks.

Did you do anything in particular to get it to boot up? If I could get mine to boot then I could work with it. I've got an external monitor that might connect, but if not, I should be able to share the screen from my Mac Mini. But I can't get it to boot.
Also, what time zone are you in? Since the same problem happened to us both on the same day, I wonder if something in the date is causing a failure in sleep/wake. I've had my fingers crossed that when tomorrow rolls around it will boot up again. Crazy, perhaps, we'll see. You give me hope.

What's wrong with my 2008 MacBook pro? It won't boot up, but I can hear it running!

i can't get my computer to turn on. I can hear a sound when I press the power button but nothing on the screen. The sound is not the boot up sound. I can also hear a fan running.

What is the sound?
Is it a sequence of beeps?
How about when you shine torch (Flashlight) on or behind the screen, can you see anything? Sometimes the backlight fails, but the computer is still running.

MacBookPro updated to 10.5.6 won't boot from 10.6.3 DVD it came with

I have a clone image 10.6.3 on an external hard drive also, and when I try to select it as the start up drive for a machine that often freezes on start it says it won't bless that drive as a startup disk, and it won't boot from the original install dvd. it's only 3 months old - does it go to hardware repair?

Since your machine is so new, I'd definitely make an appointment at the genius bar and have them take a look at it. It's one thing if it won't boot from an external clone, since there could be a problem with the external drive or how it's set up, but if it freezes and won't boot to the install disc, there's something wrong.
The Apple Store can run a hardware test from their store feed and it just takes a few minutes. That might be a good place to start. Take your install DVD along when you go--possibly it is what has a problem.
Good luck!
