MacBook Pro doesn't start up to Apple Diagnostic

I have the issue that after an Adobe Flash update the Facetime/iSight camera is no longer recognized by the system. System profiler claims that there is no camery installed. the day before I had a nice Facetime call. See Here: Adobe Flash update killed iSight camera
And to find a solution for my problem I read some Apple troubleshooting docs and Diagnostic could be helpful to find out if the cam is really broken or if its a bug.
But OSX 10.10.2 prevents me from starting up to Diagnostic mode. When I hold down D the gray screen last for 60 seconds and boots as if I haven't pressed anything. But the MBP delays the start for the time I press D. I press when I hear the sound and before the gray screen appears. Is there an issue with the startup keys?Startup key combinations for Mac - Apple Support
And because there are not enough problems the battery seems to reach the end of life. I wondered if this is no accident that the battery and the cam broke at the same day. Will the cam work when I replace the battery? Its frustrating that the battery only has 270 cycles. Apple claims 1000 cycles to be appropriate.
I have no luck with my little 13'' MBP. In December 2013 the housing top case and the logic board needed to be replaced because the USB ports didn't work. And now as the APP ended in December 2014 all this s*** happens now.

An early 2011 MBP came with Snow Leopard installed. Use the #2 disk that has the Apple Hardware Test instructions written on it.
You might also try OPTION + D on start up. Sometimes that works.
Ciao.

My MacBook Pro doesn't start; in safe mode shift CMD V the message "disk0s2: media is not present" is written on the screen repeatedly but the MacBook doesn't start. Do you have any ideas of why this should be or what I should do to resolve this?

My MacBook Pro doesn't start; in safe mode <shift CMD V> the message "disk0s2: media is not present" is written on the screen repeatedly but the MacBook doesn't start. Do you have any ideas of why this should be or what I should do to resolve this? Thanks Eamonn

Thanks for these suggestions: I have tried safe mode re-starts (both "verbose" and simple "shift" + power) to no avail. I get the error message "disk0s2: media is not present". Following this I inserted the installation disc and from there ran disc utility. The "Verify Disk" indicated an error " invalid sibling link" which it could not repair.
I also tried to completely re-format/erase the disk, but again got an error message "disk object invalid or unable to serialize".
Any ideas of what could be causing this or the best solution? I fear I am fast running out of options.

Macbook pro doesn't start up anymore

Guys i got a pretty big problem. My 1st gen macbook pro doesn't wanna completely start up anymore. When i press the startup button, I get the bong and when the apple logo appears, it suddenly restarts. So the bong appears, the apple logo shows up and then it restarts again: this keeps on going and i cant stop it unless i pull out the battery and power plug. I have no idea how this is possible: I did nothing unusual with my computer. The only alarming thing that happened before this was a kernel panic. After restarting my computer everything was fine and the mbp seemed to have recovered. So I then left it as I went for dinner and when i came back, the screen was black en frozen. So I turned of the mbp and then it wouldnt start up anymore!!!
Can anyone please help me!!!

Place the OSX installation DVD that came with your computer and hold down 'C' during the restart. That should open up the installation/repair screen. There you can check your volume and repair it through Disk Utility. If you can't fix your drive here, you can restart your machine in target mode and backup your drive (given that you have another computer to back it up to) and then hard-format and reinstall. This might be a long and hard process but it should solve your problems. If you have more questions, just post.
Cheers-

10.5.4 installed, Macbook Pro doesn't start up

Hi,
I just installed 10.5.4 via Software Update. But now my Macbook Pro doesn't startup correctly anymore. I hear the start up sound then the white screen with apple and the spinning wheel. Then then fans start to grow louder and louder until the whole unit just shuts down and is off.
Has anyone already experienced this problem? Please help.
Thanks.
Best Rob

The combo update is only available from the Apple download site. The link is in one of the other 10.5.4 threads. Software update only uses a delta update.
Try booting in the safe mode, hold down the Shift key while booting. If you get to the login screen, don't login but hit the restart button. That should allow a normal boot - it forces a disk repair.
Otherwise, boot into the Leopard DVD, select the Utilities menu and run the disk utility from there and repair HD and permission. If that succeeds, you should be able to boot normally.
The update may have actually succeeded but the cleanup failed.
If you manage to get back into your system, check the version of your OS. It may be 10.5.4
If all else fails, you will need to restore your previous system using TimeMachine, although usually one of the above techniques will usually result in a bootable system without needing major surgery.

I took it to a regular computer repair center and they said its an issue with the 1*8 gb and 1*2 gb totally 10 gbs i put in and then i replaced the 8gb with the old 2 gb that came with the computer and the issue is the same.
I tried reseting it to factory form that took 3days to download os 8 . and finally stopped by itself.
I don,t know if i had to take it to apple store?

MacBook Pro doesn't start - harddisk is not working

I am desperate. My girlfriends MacBook Pro unibody, with OS Leopard doesn't start any more. It shows the grey screen with the apple, but that's it. I tried resetting the NVRAM - it didn't help. I tried starting in Safe Boot mode - it didn't start. I have booted from the installation DVD and run Disk Utility, but it doesn't even see the partition and all the buttons to Repair or Verify the disk are grayed out. And the System Profiler doesn't see the disk, but instead just gets stuck while trying to read it.
After all this I did a deep Hardware test, but it didn't find any problems.
I suppose then that the partition, but not the harddisk is corrupt... any ideas?
And one more question: is there a way to save the data from the harddisk before trying to erase and reinstall the system, or taking it to the service?

Try putting it into Target mode...
http://support.apple.com/kb/HT1661
To try to read it's drive, or put another Mac with Firewire & a comparable OSv in T mode, hold the Option key down when booting the MBP to see if it'll boot off the the other Macs drive.
Long shot, but...
Either boot this one in Target mode...
http://support.apple.com/kb/HT1661
And recovering from another Mac, or booting this Mac from another HDD, then using Data Rescue...

Macbook pro doesn't start after a long time of inactivity

hi,
MAC OS doesn't start when I switch on my macbook after a long time of inactivity. The HD seems to turn, the non activity led is on but nothing on screen.
I have to switch off the machine by pressing the start button during five seconds and then switch on again to launch MAC OS without problem.
the problem doesn't appear if the macbook has been switched off for a short time and only appears after a long time of inactivity
I dont'know if their is a hardware problem? can somebody help me?
macbook pro Mac OS X (10.4.6)

hello,
I have a the problem when the MBP is in sleep mode too for one hour for example. It doesn't wake up and the behaviour is the same as a power on.(power ok, hd turns , blank screen, activity led on, no launch of MAC OS)
I call apple support . They told me to look at the ram stick in order to find if the ram is in good place.
No differences , the problem is still present after disconnection an reconnection of RAM.
did someone find a fix at this issue?
thank you.

Macbook Pro Shuts Down / MacBook Pro Doesn't Start Properly

I just had this problem today. When I tried to wake the macbook pro back from sleep, it didn't wake up, after closing and reopening the screen several times. Thus, I forced quit it by holding the switch button. Now, when I tried to start the macbook pro, the computer automatically shuts down in less than 3 seconds. I have tried resetting the PRAM and all that stuff but they don't seem to work. Has anyone had this issue before?

I am having this exact problem. In my case, I shut down my MBP before going to work. Once I reached work, I tried restarting and it shuts down almost immediately. I've already tried most solutions, but as I am at work, I have not been able to try the cd solution. Any help would be welcome as I do not want to have to reinstall the OS.

Macbook Pro doesn't starts and only sounds a beep

Does anyone know what to do?

I had this happen before on a fairly NEW macbook pro. Ended up, the hard drive was blown. I just ended up getting a hard drive. It worked for almost a year and then boom I try to start it up and get this. And I tried to reinstall mountain lion, etc, and it'd let me get through the install process which made me think the hard drive DID in fact work. But then as soon as it was reinstalled, boom the hard drive gone again.
I put in a new hard drive. Flawless. No problems. So in my case it was the hard drive. Although many many other people told me it was not the hard drive. If it wasn't, replacing the hard drive fixed it either way.
It had a toshiba branded in it. I put a western digital 1TB in it. Worked great. Now I have an even newer macbook pro, 2012 edition, once again I took out the hard drive and put in SSD's.

Macbook Pro doesn't start from internal disk. How to?

Hi.
My Macbook doesn't startup. I tried to repair it but it isn't possible and now I need to do one last backup copy before format it. But it doesn't pass from the grey apple screen.
I've checked the S.M.A.R.T. and it is OK. What else can I do to start from the internal disk on last time?
Thanks.
Best regards,
Telmo

Hi. Yes, I did. It goes on and on with the grey apple screen.
I just need it to boot one last time to save one Word document that I didn't had the chance to backup.
The internal disk appears on the disk utility when I star from the install disk and I select it to boot but when restart nothing happens.

My macbook pro won't start up. I get the white screen and the grey apple icon   the spinning wheel......and it doesn't change !

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
Step 1
The first step in dealing with a startup failure is to secure the 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 the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from 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.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start 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.
d. 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. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d 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 startup failure can be resolved by resetting the NVRAM.
Step 4
If a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
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 start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up 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 started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. 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 do this. Post for further instructions.
Safe mode is much slower to start 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 the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up 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, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup 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 restart as usual (i.e., not in safe mode.)
If the startup 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 the 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 restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
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 startup 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 13
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 (August 2010) keeps freezing when apple mail starts up. This happens every 2nd time I turn on my Macbook Pro. This forces me to hold down the power button to restart my Macbook Pro. Does anyone else experience this, and is there a fix? Thx

since upgrading to OS lion, my mac book pro (2010 August) keeps freezing (non responsive, requires restart) when i turn on my mac and the system is trying to open apple mail. while apple mail is attempting to collect new mail, the macbook pro freezes. this happens every 2nd time i try to start up my computer. this only started happening after i upgraded to OS lion. please let me know what I need to do to fix this. being forced to restart every 2nd time i turn on my macbook pro has been very frustrating. not sure if apple mail is also the cause of my macbook pro for being very slow during start-up (on the occasion the computer doesn't freeze).

I am having similar 'freezing' problems with many programs (Mail, Safari, iTunes, etc.). I have done a clean install of Lion instead of an upgrade when it came out. Perhaps something went wrong with my install? I'm thinking about wiping and reinstalling.

MacBook Pro doesn't want to start up anymore.

My MacBook Pro doesn't want to start up anymore.
When I turn it on, it turns on, followed by a white/light grey screen with apple logo. After a while a loading wheel appears beneath the logo and a loading bar beneath it. The loading bar loads to about 1/5 and then disappears, leaving the computer stuck on the the white screen with the apple logo and the loading wheel.
I tried to reset the PRAM, but it didn't help, it only got the startup sound to play when I turn the MacBook on.
What can I do about this? Hopefully I don't need to lose my files.
Thanks in advance,
Emil

No you don't.
OS X can be reinstalled all by itself leaving the programs and files alone, provided the drive is working correctly.
I'm not quite sure how to recover the files from Macintosh HD that I don't want to be deleted during this process.
The TM drive is almost useless because you can't boot from it to recover your latest files with.
That's why I gave the link for the undelete boot drive, you create and boot from that, access your internal drive and grab files, then you can restore from TM or other things, like the repair list of fixes I gave you.
Could you help me a little on how to backup files manually most easily?
The problem is your machine isn't booting to grab the files.
So you need to create a external boot drive, then you can access the internal boot drive directly and grab files out of your Music, Pictures, Movies, Documents folders (etc) to the external boot drive.
Most commonly used backup methods
Or is there a way to do this without deleting all of the files in my user folders on Macintosh HD?
Yes, you can choose to create a
Create a data recovery, undelete boot drive
and recover your filesnow , or you can chose to try fixing the machine without recovering your files, but your taking your chances as we don't know how seriously wrong it is yet.
If your willing to take a risk then proceed through this list, Step 1 - 8 etc., until the machine boots up.
Step by Step to fix your Mac
If the machine doesn't boot up then you need to create the external boot drive to get the files before proceeding with further steps.
If this is too much for you, then call a local PC/Mac data recovery/repair service and they will handle it for a large fee.

My Macbook Pro has recently started to mute/unmute itself randomly. VERY FRUSTRATING! It doesn't matter whether I have speakers connected or using the onboard speakers. Any suggestions?

I have looked at other forums and the fixes suggested do NOT work.
What would cause this?
How is it corrected?

Hello DChrystal
Try paying attention to the Keyboard Viewer to see if any keys are being pressed that could be causing the sound to be muted. If it is, try it in another user to see if it is software that is causing the issue or if it is the actual keyboard that is having the issue.
One or more keys on the keyboard do not respond
