My Mac book pro turns on with a grey screen with a blinking folder question mark. Help!

My bag carrying my computer fell on the ground as I was entering a cab. I checked my computer immediately for damage and it seemed to work fine. After about an two hours, I went back to my computer and it had a black screen and was getting very hot. I held the power button down and it restarted only to have a grey screen with a blinking folder + a question mark. I've already looked on the forums, and I don't have the CDs with me as I am traveling, and I don't have much backed up.
I appreciate any advice provided.
Thank you!

Hey peawok,
The following document goes over troubleshooting steps for when you encounter a folder with a flashing question mark during startup:

My mac book pro is frozen on a grey screen with an apple in the middle. It is not responding to restarting and has white letters that says panic(cpu caller 0xffffff8027259241) and so on

Press the Power button and hold it down until the computer turns off. Restart. Do you still get the same result? If so, then try booting into Safe Mode, then restart normally. A safe mode startup takes considerably longer than a normal one, so don't panic. You will also see a progress bar at the beginning.

Mac book will not boot up,only grey screen with ? on it,Why?

Why won't my Mac book boot up,start up only grey screen with ? showing?

That folder with the question mark icon means that the MacBook can't find the boot directory. That can either mean it can't find the hard drive or the Operating System data on the hard drive is somehow corrupted.
With 10.4, 10.5 or 10.6 put your install DVD into the optical drive (CD/DVD drive) and reboot. Be sure to either use the disc that came with your Mac, or, if you installed a later Mac OS X version from disc, use the newer disc. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option Key until the Install Disk shows up) until the apple shows up. That will force your MacBook to boot from the install DVD in the optical drive.
Or if you are running 10.7 Lion, 10.8 Mountain Lion or 10.9 Mavericks, boot from the recovery partition (Command +R on boot) and use Disk Utility to repair your OS 10.7, 10.8 or 10.9 partition.
When it does start up, you'll see a panel asking you to choose your language. Choose your language and press the Return key on your keyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it. When it comes up is your Hard Drive in the list on the left?
If it is, then click on the Mac OS partition of your hard drive in the left hand list. Then select the First Aid Tab and run Repair Disk. The Repair Disk button won't be available until you've clicked on the Mac OS partition on your hard drive. If that repairs any problems run it again until the green OK appears and then run Repair Permissions. After repairing use Startup Disk from the same menu to choose your hard drive for restarting from your hard drive.
If your hard drive isn’t recognized in Disk Utility then your hard drive is probably dead.

My mac book pro 2011 never pass the grey screen.

I have a mac book pro 2011, 17". For some reasons it just stop working. I have recovered the OS by holding command-R, the problem still persist. I follow the note provided by apple here: http://support.apple.com/kb/TS2570 . Unfortunately, I have lost the recovered CD that came with my computer. What are the solution for this case. Please, help if any one has any idea about this issue.
The windows safe mode is working fine, but the Mac OS safe mode does not work. I have brought the computer to an apple technician to check for the hardware error using the tool provided by apple and found all hardwares to be ok. However, after try all the solution including internet recovery, the technician insisted that the mainboard is defected. What should I do to repair my computer?

There is a grey spinny wheel that keeps spinning. Normally this stops and I get the login screen but now it just carries on endlessly

Mac book pro, Turns off and goes under protection especially with an External monitor on.

Mac book pro,
Turns off and goes under protection, sometimes without any specific motivation, but most of the time when an External monitor is pluged-in.
I use it when I work with final cut pro, and this problem it's becoming huge and changing my workplans....
It can turns off also 10 times in two hours.
In many forums I read that the CPU temp could be the problem, but I've checked it and It's always around 62°-68°....
In some others they say that the new RAM could be the problem too.
Is anybody able to help me? (Underneath you can check the Panic Report and my mac informations)
Thank you so much.
Antonio

Problems with volume when streaming a Netflix movie from my Mac Book Pro (Mid 2009) to my flat screen TV?

Hi!
Does anyone know what I need to do in order to turn up the volume when I’m streaming a Netflix movie from my Mac Book Pro (Mid 2009) to my flat screen TV?
I hooked up the HDMI adapter from my Mac to my TV and it is currently in Mirror Mode, but I can’t turn up the volume, the only audio I’m able to adjust is on my Mac.
I’ve already tried: System Preference > Sound > Output > Internal Speakers Built in output. That’s the only option my Mac gives me.
Any suggestions?

Hello jguti,
Thanks for using Apple Support Communities.
I understand that your external display connected via HDMI is not being detected by the computer. At this point, the best bet for your next troubleshooting step would be to reset the system:
Reset the system
You can reset the Mac's parameter RAM and SMC.
Reset the resolution
Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.

HT2486 can I have two contact lists on one mac book pro? I need one to sync with my iphone, one to sync with my husband's iphone.

can I have two contact lists on one mac book pro? I need one to sync with my iphone, one to sync with my husband's iphone.

I agree with Chris CA that this is the way I would *expect* iTunes to behave.
When I look at iTunes from my account (my music is in ~/Music/iTunes/ and not available to my spouse's account), I can see in my music library all my rips and my purchases, just as I would expect. I can use Store>View My Account (<myAppleID>) and all is as expected. Home sharing is NOT on.
Doing the same from the other account is not much different, actually. Nothing in the library yet, of course. Store>View My Account (<herAppleID>) also works. I CAN authorize my computer to play her music. I CAN view her iTunes purchases. When I attempt to download the purchases to HER library, though, I get the following dialog box:
Now I interpret this to mean that this computer (mine) will not download from a different AppleID (also mine) for 90 days. Is that [interpretation] correct?

I have a problem with iphoto (have a mac book pro): the icon in the dock appears with a question mark, and the application is gone!!! Can someone tell what's going on? Yesterday I had the same problem with itunes: I downloaded the last version (it's free), but I cannot do the same with iphoto, and more important: I need to know what is happening!!! Please help me!

Applications should not disappear all by themselves.
If they are then that coud indicate serious problems with your hard drive.
Backup everything up as quickly as possible.
Using Disk Utility verify your system disk.

I have microsoft outlook installed on my Mac book pro, I can only use the outlook with the office server where it was setup, I can't use outlook else where, is there any way I can reset the settings in order to be able to use outlook every where?

I have microsoft outlook installed on my Mac book pro, I can only use the outlook with the office server where it was setup, outlook won't work out of office, is there any way I can reset the settings in order to be able to use outlook every where?

I can see my folders by clicking the X next to my name on the Inbox Folder. So I have my folders now, just cannot see them in the left colum or see multiple windows on Outlook. At this point, I can use the folders, just with limited functionality. Thanks -Gina

My mac book pro turn on alone

I have been noticed that several times a week at the same time (0.00 h) my mac book pro turn on alone. What Can I do to fix this issue ? Thanks in advance

Open system preferences and go to the Energy Saver section then click on the Schedule button, bottom right hand side of that window, and see if you have "Start up or wake" option checked.

Mac Book Pro turns off

Hello,
My Mac Book Pro turns off without reason. It hypernates. At first I thought it was the battery but It is not that. It says it has 2:30 left, but to turn it on I need to plug in the adapter. It does that for 2 days now.
Thank you in advance,
Chrystalla

The battery has an integrated microchip that acts as a "fuel gauge." Calibration resets this gauge, which allows the OS to better determine times to charge and discharge the battery. Calibration should be done approximately every two months. Failure to do so for a long period of time can result in the microchip "fuel gauge" in the battery losing the ability to accurately determine the remaining charge, and it will report that there is more charge in the battery than is actually present. As a result, the computer will not initiate Safe Sleep at the proper time, and instead undergo a hard shut down, one of the main causes of hard drive directory damage.

Why is my mac book pro mid 2012 display green flickering screen?

Why is my mac book pro mid 2012 displays green flickering screen? I was able to return the screen back to normal after i turn the lid up and down.
Is this a hardware issue ? should i return to applestore since the warranty still valid?

It seems like your display is damaged. As your computer is in warranty, take your Mac to an Apple Store or reseller to get the display replaced for free, as it's in warranty

This has never happened. I have tried to do the command-option-p-r trick and that didn't work. HELP

That folder with the question mark icon means that the MacBook can't find the boot directory. That can either mean it can't find the hard drive or the hard drive data is somehow corrupted.
Put your install DVD into the optical drive and reboot. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option key until the Install Disk shows up). That willforce your MacBook to boot from the install DVD in the optical drive.
Once it has finished booting and you Choose Your Language and you are at the Install screen launch Disk Utility from the Utilities menu. Is your Hard Drive in the list on the left?
If it is then select the First Aid Tab run Repair Disk and if that repairs any problems run it again until the green OK appears and then run Repair Permissions.
If your hard drive isn’t recognized in Disk Utility then your hard drive is probably dead.

You enter Target Disk mode by launching the iMac with the "T" key held down or by the method you used. It's used so another Mac connected to it can access the files as if it were another external HD.
