I'm getting the grey screen during start up and can't boot the computer - MacBook Pro with lion.
I did a command r after doing some research but got nervous that it would automatically wipe my hard drive and reinstall OS.
I was nervous because it asked me for language for software use before any options were presented (such as repair via disk utility). It looked similar to an OS install.So I powered off....Is there a risk at command r will result in wiped HD without me actively making that choice?Repair the Hard Drive and Permissions - Mavericks, Lion/Mountain Lion
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
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 then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.

So my late 2012 MacBook Pro was sitting on my desk when the desk collapsed. The computer fell with it and I was quite scared at the moment, but thankfully I opened it up and it worked perfectly fine again.
I was later watching a YouTube video and pressed the back button. The screen then froze, and I could not force quit safari. Then this weird clicking noise started to happen. It was coming from the right of the trackpad. That's when I decided to force shutdown the computer with the power button.
I let it sit and then decided to turn it back on. The clicking noise then came back and there was just a blank screen on the boot up. Eventually a grey folder with a question mark started flashing on the screen. That was all it did so I decided to turn it off again.
I'm going to take it into the Apple store ASAP, but I'm curious if my hard drive is damaged and if I will need a new one, which would erase everything on my Mac. So I was wondering if there is anyway to back up the hard driver even if it doesn't boot up all the way, or turn on the computer all the way.
P.S. I have never backed up my hard drive so I wouldn't know what to do.You may have damaged the HDD which is located in that spot. I would take it in for service.

My MacBook has a grey screen with a folder and a question mark in the middle what does this mean?

It means a valid system cannot be found. You need to reinstall OS X.
If you have Snow Leopard:
Reinstall OS X without erasing the drive
1. 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.
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.
If you have Lion or later:
Reinstall Lion, Mountain Lion, or Mavericks without erasing 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.

My macbook pro is stuck on grey screen with apple symbol in center with the progress circle under it continusly spinning. After I had turned it on. Prior to turning it on I had to force close and shut down a few hours prior. Please Help I have tried everything I know to do
Unfortunately this means that there is a problem in the boot sector of your hard drive. It might be indicative of a fundamental corruption in the coding that allows your computer to boot your operating system from your hard drive. I had this problem twice and it resulted in me having to get a new hard drive and restore my data.
In other words, your computer can't talk to your operating system so you can't access your data.
Here is my advice: DON'T CALL APPLE TECH SUPPORT though they are kind and usually helpful it will take you an hour just to explain the situation and they will only tell you to do what I'm gonna say here.
First: Shut down your computer completely
Two: boot up while holding down the following keys: command, option, p, and r. The computer will reboot 3 times. This solution will likely fail so if you're frustrated skip to the next step.
Three: Boot up while holding down the option key. Select recovery drive. Select your default language. Select disk utility, click on Macintosh HD, and select "verify and repair volume." Likely the verification will produce some line like "unused node not erased." Or something like that. If anything using the words "node structure" comes up, you need a new hard drive.
If after verification and repairs you still can't boot I sincerely hope you have apple care because you will need a new hard drive. Set up an appointment to come in to the apple store, they will tell you to go and get data recovery, just ask them to give you the old hard drive. Unless you have an up to date backup in which case you can just restore from that. If you're lucky the only issue is with the boot sector which means that if you ask them to give you the old hard drive, you can buy an enclosure and you have effectively been given a free external hard drive. It still works to store data just not to load an operating system.
If you have a back up drive bring it to the apple store and they'll do the whole thing right there, it should take around an hour and a half but may take longer.
Hope this helps, it's annoying but it's your safest bet.
All the best. -

If you replaced the Ram in your machine at any time, you may not have been aware of the fact that Apple computers have always been a little picky when it comes to 3rd party Ram. Apple computers have always run very well on 2 different brands.

This first link is from other world computing and none of us on these forums to my knowledge have heard of any bad ram from either Other World Computing
or Crucial Ram.

The only difference I am aware of is that Crucial offers a download and will tell you exactly what Ram your computer is capable of using and the prices that are available.

My MacBook Pro 13" (2012) is running Windows 7 on Bootcamp and there is an issue with the headset I'm using. I use a cheap Logitech Stereo Headset H130, but since there is only on audio plugin on the computer, I purchased a 3.5 mm 4-pin smartphone audio adapter thingy. That allowed me to put both my the sound coming to my headset & the microphone on my headset onto one wire. Everything worked wonderfully when running the Mac OS since they probably have support for that kind of stuff. The problem is though that once I try to use the same method in Windows 7, the OS doesn't recognize my headset microphone at all, but, instead when recording my voice decides to use the built-in mac microphone. Using this adapter still allows me to hear from my headset, but not use the microphone and that becomes a problem. It might be so that Windows 7 doesn't have support\drivers for that... How should I continue from here on out? Any advice?
From what I have read from others on here you may be out of luck. You would need the appropriate Windows drivers for the Cirrus chip in the Mac and no one has been able to successfully locate them. Apple wouldn't support this since Windows is an optional install.
Sorry to bring the bad news. -
MacBook pro keyboard doesn't light up all the way, I don't know why and I was wondering how much it could cost for repairs.
If there is Warranty or AppleCare it will be covered at Apple Store. If no coverage, Apple does not repair iPhone 4 Power/Lock Button, for $149 they will give you a perfect replacement iPhone 4 exactly like yours with a 90 day Warranty. For the time being or as a permanent solution you can use perfect Virtual Lock Button. Tap Settings App > General > Accessibility > Assistive Touch > ON > tap the new small white screen button > Device > Lock. You can even use this button to turn the iPhone OFF. To turn iPhone ON, connect to power, ie charger or USB port of computer.

My computer has a white screen at start up and sits for hours. How can I fix my computer?
My computer has a white screen at start up and sits for hours. How can I fix my computer?
Take each of these steps that you haven't already tried. Stop when the problem is resolved.
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 you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
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, or if a firmware password is set, or if the startup volume is a Fusion Drive or 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 10. 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. -
I have a problem with Mail on my Macbook Pro. It is configurated with a gmail account, and now I can't access the mail. Is it possible to reboot the account or..? Please help:)
The question mark means the computer cannot find a bootable volumes so can;t do anything, That, combined with annoying sounds, strongly suggests a failed hard drive.
You can ask a "genius" at an Apple Rtail Store to test it but I'm pretty sure the drive is kaput. I'm hoping you had your data backed up. -

MacBook Won't Boot Up All The Way
Hi, I have had my macbook for quite a while, and it has had problems before like a non working battery and random brightness changes but ever since I installed the latest security update it will not boot up all the way, first it takes a long time for it to pass the white screen with the Apple logo and loading circle, after that it reaches a blue screen, with no response. Once it made it to my desktop background but none of the icons or dock showed up. Any help?
I have the same problem mentioned in the original message. I downloaded the updates and my computer will no longer boot up. I put in Disk one of the install disc, but that did nothing and now I can't get the disk to eject. I was going to try disk 2, but can't get disk 1 out.
