Start-up problem with my Macbook - light stays on and screen stays black?!

Hi, sometimes when I start up my Macbook the switch-on light stays on and the screen stays black. Then I have to turn it off and when I restart it boots normally. What can this be? I resetted already the PRAM and the firmware is up to date. Perhaps someone understands german. Therefore I added my german post... Many thanks in advance!
Hi, hab ein seltsames Phänomen. Manchmal, vor allem nach ausgeschaltetem Zustand über Nacht, leuchtet nach dem Einschalten das Einschaltlicht auf und geht nicht wieder aus, wie normal wenn das Macbook startet, sondern bleibt an und der Bildschirm bleibt schwarz. Dann schalte ich das Macbook mit dem Ausschaltknof aus und warte ein paar Sekunden und schalte es dann wieder ein. Daraufhin startet es ganz normal. Woran könnte das liegen? Hab schonmal PRAM resettet und die Rechte auch repariert. Der Hardwaretest zeigt auch keine Probleme an. Kann man(n) noch irgendwie überprüfen, woran das liegen könnte oder hat das Problem auch schonmal jemand gehabt? Mein Macbook ist gradmal 2 Monate alt und hat das Problem erst seit kurzem. Könnte das vielleicht auch an einer Software liegen, die ich installiert habe. Kann sowas auch Auswirkungen auf den Bootvorgang haben? Bin Laie und würde gern wissen, ob sowas auch an der Pufferbatterie oder einer kalten Lötstelle liegen kann oder könnte das Macbook da dann gar nicht starten. Wäre für jeden Vorschlag dankbar... Vielen Dank schonmal im voraus!

Hi,
put me on the list as well. I was already in contact with ADC and it seems to me that they acknowledged it as a bug. I'm using a Mini-DVI-to-VGA adapter. And sporadically when unplugging it the internal display stays black or switches to the blue background and hangs there.
As I heard from friends who are using the Mini-DVI-to-DVI adapter in the same use case, this doesn't happen to them.

have a problem with my MacBook Pro.5,3 and monitor. Intermittently, the desk top screen becomes broken up into vertical sections, which appear in the wrong order, creating a haphazard picture.
The Apple icon, usually at top left corner, appears in top right corner in a strip including all that left hand. When the computer is restarted, the screen goes back to normal. But I have to move the mouse to the far left of the screen and then up until it reappears on the far right hand side of the screen so that I can hit shut down button.
It seems to happen randomly though always on desk top and sometimes when I move mouse and computer switches on from rest mode. My large flat screen is relatively new.
The video card on this computer, which is approximately two years old, is Nvidia FeForce 9400M.
Any help would be welcome as my usual source of assistance is not available and I am not well versed in workings of the Mac although I have used one for many years.

That sounds like a Hardware problem.
You may be able to confirm that with Apple Hardware Test, or make an appointmenst for a free Genius Bar evaluation.

If this is a fairly new Mac running either v10.7 Lion or v10.8 Mountain Lion she can use Lion or Mountain Recovery to repair the startup disk or reinstall OS X.

Huge problems with my MacBook: Invalid Node Structure and More!

A couple days ago I was browsing the internet, and when I closed Safari, the system froze. I couldn't even force quit out of anything, so I had to shut it off manually. When I tried to turn my computer back on the next day, I couldn't get past the Apple screen. The little wheel would keep spinning, but I could never get anywhere.
Then, I tried to boot from the Leopard DVD to possibly reinstall Leopard, hoping it would work. At first, no drives would show up to install to, but for some reason, they eventually showed up. Problem is, I don't have enough free memory to reinstall Leopard. Furthermore, I've tried to fit it on the space I have, and it says that the install failed, so I can't reinstall Leopard.
I also went to Disk Utility from the DVD and tried to repair the disk. The only option available was to Verify Disk, but when I go there, that fails, and it says "invalid node structure."
I'm not sure what happened to my computer because it seemed to come from nowhere. To sum up, I cannot log in to OS X, or even XP on a separate partition, I can't reinstall Leopard, and I can't repair the disk. I've read about how DiskWarrior might help, but I can't get in to OS X. Does anyone have any idea what happened or what I can do? I haven't backed anything up, so if I'm screwed, then so be it, I guess. Just wondering if anyone has any explanations or suggestions. Thanks.

Interesting how many people have this same issue. A friend of mine has brought me her white Macbook Intel Core 2 with Leopard and it had a folder with a question mark instead of the apple at startup. I was able to boot using the Mac Install DVD and ran Disk Utility. It said something like "Invalid Node Structure" and "Cannot Repair". Unfortunately DiskWarrior will not fix this. I tried it to no avail. I'm resigned to the fact that a new hard drive is necessary.
The HD in there is a Hitachi 120GB.
It also wouldn't let me erase the disk nor partition it. Then, one morning I woke up and it was able to erase! So I erased, then installed Tiger. It seemed to be working fine. So I rebooted from the Leopard drop-in disk and installed Leopard. Then I restarted, and BAM! back to the question mark folder. Now I'm back to where I started. Other threads
I forgot to mention that my friend had photos and music on the HD that she couldn't do without and I was able to recover that data using Data Recover II. First I had to use SuperDuper to clone my own computer onto an external drive so I could use it as a boot drive.
For now the only solution is to buy a new internal hard drive and reinstall the OS. And regularly backup!!
So I guess this issue has not really been solved, but hopefully you have warranty. Unfortunately for my friend, this happened a week after her warranty expired.
Good luck.

try inserting and removing the headphones in and out of the audio jack. The toggle switch is stuck and your mac thinks the headphones are still plugged in.

If there is no loading bar, it's usually a problem with a third party kext file in OS X itself.
You can press the power button down to force a hardware shutdown, then reboot holding the shift key down on a wired or built in keyboard, this will disable them and you go around and update your third party software.
Gray, Blue or White screen at boot, w/spinner/progress bar
Also take this time to backup your users files off the machine if possible.
Most commonly used backup methods
Sometime that won't work and you need to do more

I am experiencing some major problems with my MacBook Pro. I have had some issues with it turning on/off at random times, but today, when starting, I get the grey start-up screen and a recovery bar. After filling in approx 1/4 of the way, the machine dies. After starting it in recovery mode, it will not allow me to download OS X Mavericks- it says the disk is locked. Any ideas? I do not have a back-up and do not want to erase everything before I have explored my options. Help?

try forcing internet recover, hold 3 keys - command, option, r - you should see a spinning globe
most people will tell you to do both pram and smc resets (google) and if you still have issues, either clean install (easy) or troubleshoot (hard)

Start up problem with macbook pro

i have a problem with my macbook. when i start up the macbook after pressing power button it turns on with apple logo and then convert into a stop sign (like a circle with slash ).it does not proceed further .what should i do ??

The following support article is somewhat outdated. Where it refers to booting from an installation disc, you should boot from your recovery partition by holding down the key combination command-R at the chime.

What backups do you have?

I am having problems with my macbook pro and the dock. About every fourth time I start the computer, the dock flashes on and off, then goes completely off and all I get is the spinning ball with brief moments of the cursor. But the computer locks up.

Do you have Parallels installed by any chance? There is a known problem that causes symptoms similar to this. You do not need to actually be running Parallels at the time and nothing in ActivityMonitor would point to Parallels. An update corrects the problem:

Having problems with my macBook Air wifi staying connected

I'm having problems with my MacBook Air staying connected to wifi....Help - Very frustrating!!!

When you go to perform a software update or make a system change it'll prompt you for an administrator's password. If you're the only user on the machine, you're also the administrator.
If you've forgotten this password it can be reset using Disc 1 of the System Restore DVDs that came with your computer. Because the MBA lacks an optical drive there are two ways to perform the password reset:
1. Purchase/use the external, USB-based MacBook Air SuperDrive
2. Use CD/DVD sharing between another, compatible computer on your network
Steps on how to do this are found between 46-49 in the owner's guide that came with your machine or it can be downloaded via the web at:

When i try to wake my macbook after sleep the keypad lights up but the screen stays black. I have to switch off and restart. How do I fix this?

After my Macbook goes into sleep mode it sometimes won't wake. The keypad lights up but the screen stays black. This problem has only occured after updating to OSX 10.7.2.
All I can do is switch off and restart. Then any programs I have not 'quit' all open.

OK, I have a fix.
After spending about an hour online with Apple Care without success, I did a reinstall of the Lion OS. It fixed the problem. I was concerned that I would lose data or settings, but the reinstall was seemless and everything was the way it was before the reinstall except that the "black screen on wake" problem was fixed.
I started the reinstall before I went to bed and it was waiting for me the next morning.
Here is a link to the page on how to do the reinstall:

Is there a phone number to call Adobe. I go around an endless loop pressing their contact info tabs? Maybe someone at this sight can help. I am new to digital photo - I have been a B&W film photographer for many years. I have a problem with a Macbook Ai

Is there a phone number to call Adobe. I go around an endless loop pressing their contact info tabs? Maybe someone at this sight can help. I am new to digital photo - I have been a B&W film photographer for many years. I have a problem with a Macbook Air. It was working fine - I was using LR and a message came on the screen that said something like the memory was dangerously low. I stopped and tried to delete LR files. I couldn't do it. I closed the program and tried reopening and got the message that there is not enough memory available to open LR. I contacted Apple. They spent a half hour on the phone with me and eventually told me they didn't know how to help. The tech said that LR had gobbled up all the memory and said I should contact Adobe and ask where and how my photo files are stored and to delete them. I have several back-ups. Thanks - Arthur

This sort of error message only comes up for Lightroom when your hard disk is full. Indeed this has nothing to do with internal memory as that will be intelligently be dealt with. If you have a mac Book Air that is not so surprising as the cheapest versions come with very small hard disks and if you shoot raw with any recent camera, you'll fill up your hard disk very quickly and you can probably only store a few months of pictures if you are a typical photographer. So the bottom line is that you need to create some room on your hard disk. You should move some of your originals to an external hard disk. You can also delete some of your backup copies of your catalog file that Lightroom automatically generates every few days and that quickly gobble up hard disk space. So first figure out how full your hard disk is. To see that, go to the apple menu, hit -> About this Mac -> More info->Storage. You should see your internal hard disk on top and you'll find that it is almost entirely full with photos. Now find your Lightroom catalog file using Finder. It is usually in a folder in the Pictures folder in your home directory. You should see a Lightroom 5 Catalog.lrcat file, a previews file and a folder called backups. Inside the backups folder, you'll find a lot of subfolders. They have names that show the dates the backups were created. If you have backups of your entire hard disk, you can delete these backups when they are older than a few months. I usually only keep the last 4 around. Just drag the folders into the trash can on the dock on the bottom of your screen and empty the trash. This will probably free up enough space that Lightroom will already run again. Now start thinking about where you will want to store older images. If you have a good USB3 or Thunderbolt hard disk that is probably the best option. There is a video here by Adobe that has some instructions on how to do this: Is Your Hard Drive Full? Here’s How to Move Images to Another Drive in Lightroom. « Julieanne Kost's Blog If that doesn't work because you don't have enough hard drive space to run Lightroom yet, here is another set of instructions to move your files using the finder to the other hard disk: How do I move only my photos to another hard drive, leaving the catalog where it is? - The Lightroom Queen. If you follow that, as soon as you confirm all your images are on the new hard disk, you can delete them from your internal one. She is not so clear about that part but if you don't delete the originals that you moved off you don't free up space. You should move the folder structure over to the new hard disk and then reconnect the folders in Lightroom. That should make it refind all your images.
That said, if you are uncomfortable with the computer in itself, your best bet is to find a local photography club. There is invariably a Lightroom savvy person in there that could help you move your files. That might be your best bet if you are uncomfortable moving these yourself. A general mac savvy person like you would find at an Apple store or so generally will not be able to help you with this except when they are photographers themselves and know Lightroom. You might get lucky with that.
