MacBook Pro 15in showing gray screen on start-up
Okay, so basically trying to format my Macbook pro, I guess I deleted the software on my computer as well. Stupid me, didn't back my computer up. All that shows, is a gray screen with a folder with a question mark on it. I have the OS installation disk on an external CD-ROM drive and all that pops up when it's plugged in is the apple logo. Ive tried CMND-R, CMND-C, CMND-V, and just simply pressing the option button at startup and nothing has seemed to work, i end up at the same screen. When I just did the option, it gave me the opportunity to use the disk, but it goes right back to the apple screen. If anyone could help, that'd be FANTASTIC. Please!!
You have a Retina model MBP. It did not come with installer discs. You would use Internet Recovery:
Install Mavericks, Lion/Mountain Lion Using Internet Recovery
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
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. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
This should restore the version of OS X originally pre-installed on the computer.

MacBook Pro mid 2010, gray screen at start up, boot from dvd not working.
Backstory:
I was in the process of installing Windows 7 using boot camp, but I was a little bit low on HD space. So, I deleted the user account that had a ton of stuff, and did some other crap that messed up my hard drive. So my computer just won't boot. It shows a gray screen 24/7, going into safe boot/safe boot + verbose doesn't fix the problem. I tried booting from an OSX Leopard dvd, but it won't work when I hold down C, and when I choose the Mac OS X Install DVD option after holding the option key, when I click the arrow button it freezes and doesn't boot. I have Lion installed, and apple says not to boot with an older version of OSX DVD, but there is no Lion DVD.
What do I do?
PS: I'm trying to boot using the DVD so I can reformat my hard drive, trying to do so in Recovery HD doesn't work because it says it 'Can't unmount drive'.Rockswim,
did it do that only once, or does it do that every time you restart it? -

Macbook pro-Freezes with black screen at start up.
Macbook pro-Freezes with black screen at start up. I've tried inserting the Mac OS X install disc to run the hardware test(Restart and hold down D), But it still does nothing. Just the black screen. Now I can't get the disc out. I've tried holding down the track pad key upon start up but that doesn't work neither.
What do I do??? Please help.Remove the battery to find your serial number in the battery bay. Then you can look your MBP up on EveryMac.com:
http://www.everymac.com/ultimate-mac-lookup/
That will give you all the information on your Mac.
This is assuming that you have the MBP with the removable battery and not the unibody. The unibody has different graphic chips.
Good luck!

My macbook pro 2011 shows grey screen with apple logo and want start
i was just using my macbook pro and it freezed for a while not responding and i turned it off by pressing the power button. afterwards, i turn it on and it shows a grey screen with apple logo but want start pls somebody help me because am having "my life" on the machine
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 boot failure is to secure your 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 your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.a. Boot into Recovery by holding down the key combination command-R at the startup chime, or from a local Time Machine backup volume (option key at startup.) Release the keys when you see a gray screen with a spinning dial. 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.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. 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
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot 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.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode.* The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
Safe mode is much slower to boot 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 your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
*Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Post for further instructions.
When you boot 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, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot 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 reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see step 1.) Select your 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 reboot as usual.
Step 6
Boot into Recovery again. When the OS X Utilities screen appears, follow the prompts to reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
Step 7
Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a backup.
Step 8
A dead logic-board battery in a Mac Pro can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.
Step 9
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested. -
Macbook Pro 2009 has gray screen, safe mode won't work
I have a Macbook Pro 2009, with a new hard drive installed in August of 2013. I opened my computer a couple days ago to a gray screen with a prohibitory sign and a spinning gear that will not disappear. I have no backup and tried to backup my hard drive to an external drive in Recovery Mode, but I got an error message and the backup did not work: the image could not be created. So I decided to try Safe Mode, but the Macbook will not enter safe mode. Is there any way to get onto the computer just to backup a handful of files onto an external drive before I format my drive and start over? Am I doing something wrong by trying to enter safe mode? (I held down the Shift key after the chime and released it when the Apple logo and the gear appeared) Any help is appreciated. I've read all the topics in the forums I could find on this issue, but none of the directions seem to help. Thank you.
LisaLoParo,
no, you’re not doing anything wrong in trying to boot into Safe mode.
I can think of three possible alternatives to Safe mode to try:
If you have an external disk, you could boot from the grey Mac OS X Install DVD which came in the box with your MacBook Pro, and try copying files from your internal disk to the external disk;
If you have a bootable external disk, you could boot from it using Startup Manager, and try copying files from your internal disk to the external disk;
If you have access to a FireWire 800 cable and a second Mac with a FireWire 800 port, you could try booting your MacBook Pro into Target Disk mode so that it can be used as an external disk from the second Mac, and try copying files from your MacBook Pro to the second Mac.
You’d only need to try one of these three alternatives; if you try one of them and it doesn’t work, then you’d get the same result by trying either of the other two. Good luck. -
Macbook pro freezes with grayed screen
MacBook Pro 5,5; OSX 10.6.8
Repeatedly crashes with a translucent gray veil that moves down the screen, and a message box in the middle of the page saying you have to turn off the computer by holding down the power button and then restart.
I think this happens almost always in Safari or Thunderbird - the programs most used.

MacBook Pro hangs in gray screen after security update
I just allowed software update to download and install the latest Safari update and Security update 2009-6. During the restart my macbook just hung on the gray screen with the spinning gear.
I've tried starting in target disc mode but the iMac doesn't register the MacBook's HD.
I started from the install disc (10.4.5) and launched disk utility but it won't read the HD either.
I tried Safe Start-up, resetting PRAM but still the hang.
HELPIf not for the coincidence of a restart after those software updates, I'd say
you need to get a correct version of Disk Warrior and see if it can repair
or rebuilt the hard disk drive's Directory; since that is a likely item to have
been corrupted somehow. And corruption of data, including the System,
is a serious matter. A near-capacity or over-full hard disk drive can cause
odd issues including corruption; so there may be more going on in the Mac.
Other third party disk utilities may be able to help get into the failed computer
and the problem is likely the hard disk drive. Sometimes, a software issue in
a drive can related to a hardware failure; so to consider a strategy that may
include a new drive for the computer and an external enclosure for the drive
that is now in the failed computer, to then maybe further your recovery of data
if it comes to that.
Good luck & happy computing! -
Macbook Pro Stuck at Gray Screen When Entering Boot Options
Hello apple community,
I have a 15 inch MacBook Pro 2008, and I decided recently to replace the 250 Gb hard drive with a new WD Black 500 Gb hard drive. I backed up all the data onto my external hard drive and replaced the hard drive. Now I am trying to enter the disk utility to boot from the disk utility by holding the option key. When I turn on the computer and hold the option key it gets stuck on the gray screen. Does anybody have any idea why this is happening? Thanks.OK. When you say it doesn't work does that mean you cannot see the drive in Disk Utility? Of course that means you need to boot from another drive such as your external backup. If you happen to have a Snow Leopard DVD to boot your computer then you could try with that. But there isn't much you can do if you don't have another bootable drive in an external enclosure or other form of hookup like a universal drive adaptor.
Your model is not new enough to use Internet Recovery. I don't know what more to offer. You cannot even verify that the new HDD is OK by putting it in an external enclosure. -

I honestly don't remember the year.
Also, no backups at all. I checked my box for original install disks and don't see any so I assume they don't come with any, anymore. Any help is appreciated!Mac OS X: Gray screen appears during startup - Apple Support
-
This started happening around the beginning of this year. I contacted Apple Support and they worked with me on-line and over the phone. It happened again the next day. After it happened about 20 more times, I took it into the Apple Store and they decided to reinstall the OS. Since then, it has happened about 10 more times.
This has happened with and without attached devices or flash drives. It has happened on different wi-fi networks. It generally happens when I am navigating with the track pad or with a mouse. I don't recall ever leaving the room and returning to find the gray screen. In other words, it happens shortly after I have moved the cursor. I've noticed the pinwheel usually appears before the gray screen.
Any suggestions?Talbott Jones wrote:

Bad sectors on the hard drive or failing drive, pinwheels usually means there is a delay of some sort from either the network or the storage drive, but not exclusive.
If you reboot to gray screen, hold the shift key down while rebooting, that may get you back in

Macbook Pro boot shows black screen with white text cursor
Hello,
I have a MacBook Pro 7,1 MC374xx/A running Mavericks. My box has two internal hard drives in it. One had the Mac OS installed to it, and the other has absolutely nothing on it. I decided to give Boot Camp Assistant a try and chose the hard drive with nothing on it to install Windows on. I also had an external USB DVD drive attached with the Windows 7 installation disc on it.
So, next thing ya know, my Mac reboots and loads a black screen that says "Memory Overload." I take out the external USB drive and restart. Then it said, "No boot devices found." Now for whatever reason, it's just a black screen with a white text cursor.
What the heck happened?
I selected command R and confirmed that I installed Boot Camp on the right hard drive (the drive that did not contain my Mac OS). Then, I completely erased everything from the drive with Boot Camp on it. But still..black screen with white text cursor.
I have no Time Machine backups available so I'm forced to reinstall the OS. Any idea why this happened? It seems I must have attempted to install Boot Camp improperly. Any ideas or instructions on what to do now or how to install Boot Camp successfully on the Macbook Pro I own?
Earnestly,
SpeckBoot Camp- Windows installation boots to black screen with blinking cursor.

I cannot keep my computer from showing applemail mailboxes when I start up. When I go to system preferences, users and groups, login items nothing is listed. If I try listing mail and then restarting and deleting it, that does not work. What to do next?
System Preference > General
At the bottom of the section "Number of recent items"
uncheck the box next to "Restore windows when quitting and re-opening apps".
Best. -
On startup a blank white screen shows after startup tone and followed by 3 clicks from the speakers. The light at the front of the computer then flashes 3 times at intervals. Startup doesn't progress past this point. I've attempted to put it into safe mode but no luck. Any help?
