Snow Leopard is a Mac OS X version. You say that it's the version you have in your Mac (10.6.8). Do a back up of your files, format the hard drive (using Disk Utility) and reinstall again

I went into recovery mode - and keep receiving error 4005 - tried different usb, computers, did all updates possible nothing helps, my iphone screen shows apple logo and constant waiting circle
Same here. I tried to update my iPhone 5S and iPad 4 to 7.1 but iTunes wiped out them. This thing already happened for iOS 7.0.6 update. What happened to Apple? I am really curious whether Apple is aware of this problem.

Hi, I downloaded Yosemite this evening. It downloaded fine, it installed fine and then it restarted the Macbook. Now it seems to be frozen. I have nothing but a grey screen with the apple logo and a bar that is half black and half grey. It's been like this for over an hour. Should I worry or is it still working at something? How do I fix this if it's not still working at installing something. Thank goodness for this poor old pc as backup.
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. -
Macbook pro will not boot. I get the gray screen, an apple icon and spinning wheel. I tried to start in safe mode, but get this same screen. The only thing different is that I added the zedge update app to do a sync for adding ringtones to my apple cell phone. How can I get a good boot. I am fairly new to apple computer.
Reset PRAM: http://support.apple.com/kb/PH4405 and then try a normal boot.
Run the Startup Manager to select Startup disk: http://support.apple.com/kb/HT1310
If those did not work your disk may be sick or dying. The top priority at this point is to make a backup copy of your data.
Check the health of the disk. Boot in Recovery Mode (Boot, Command-R). Run Disk Utility. Click on the upper left disk icon. Does the S.M.A.R.T. status say “Verified”? If not the disk/SSD is unhealthy and needs to be replaced. Even if it does not show “Verified” you can still attempt a backup.
Click on the icon indented below, usually called “Macintosh HD” and Verify Disk. If it finishes with a green “OK” message then all is well with the disk. If it shows errors in red then you have found a problem to address once the system is backed up. Do not attempt software repairs until you have secured the data.
If the disk will not show up at all in Disk Utility as your ran the tests above then it may be dead or it may have a bad internal SATA cable. A trip to an Apple store for confirmation would be in order.
If you have an external disk drive you can use as a backup drive then do so. If not Google “Hitachi USB 3.0 external hard drive 1TB” to purchase one or go to a brick-and-mortar store (including an Apple store) to pickup one. Any 1 TB external drive will do.
Assuming it is still breathing you can try to recover the data without booting from the sick disk.
Reformat the external disk. (This will erase all data on the external disk.)
Boot in Recovery Mode. Start Disk Utility. Plug in the new disk. Select it’s disk Icon (the second one down, left justified). Select the Partition tab.
Partition Layout > Single Partition
Name: Emergency Recovery 1 (or whatever name you wish to use)
Format: Mac OS Extended (journaled)
Options… > GUID Partition Table > OK
Apply
Select the Restore tab.
Drag the old system volume (Macintosh HD) to Source.
Drag the new disk volume (Emergency Recovery 1) to Destination.
Click on Restore.
It may take a long time for the backup.
If that will not complete post back for other emergency data recovery methods, including those from a brody.
If the backup succeeds, use the First Aid tab in Disk Utility to select the old volume (Macintosh HD) and Repair Disk. If it does not finish with a green OK message try to repair it once or twice more. If it repairs with a green OK message, will it boot normally? If not, boot from the Recovery Partition and reinstall OS X.
If it is still not healthy, post back for further instructions. -
My macbook will not start up. It gets stuck on teh opening page with the apple. It was working fine and all of a sudden i cant get it to work. Does anyone know what could be wrong with it? Or, is there a bypass to the start up page?
You won't lose your files unless something goes very wrong -- which may already have happened. You absolutely must have a backup before you do anything else. If you don't already have one, boot from your installation disc and follow the instructions in this article under "Instructions for backing up to an external hard disk via Disk Utility":
Mac OS X v10.5, v10.6: How to back up and restore your files -
IBook will not start up past gray screen w/ apple logo
iBook will not start up past gray screen w/ apple logo. So I have zeroed out the hard drive and reinstalled tiger. No change except if I start up holding shift it will boot and welcome comes up then black screen that says you must restart by holding down power key.
Zeroed out the HD again with same results. Also I have a iBook G3 with the same symptoms.What you are experiencing is a kernel panic.
Try starting up from the Mac OS X Install Disc by inserting the disc and restarting your computer, holding down the C key as the startup chime is ending. Then choose Installer > Open Disk Utility (in Panther) or (in Tiger) click 'Next' at the language screen and choose Utilities > Disk Utility and select the hard drive in the left column. Choose the First Aid tab. Click Repair Disk to test and repair the hard drive.
Once you have repaired the hard drive with the Install disc's Disk Utility, then try to restart normally, and go to Applications > Utilities > Disk Utility. Click on the top hard drive icon in the left sidebar and note the S.M.A.R.T. status at the bottom right of the pane. What does it say?
Select the named boot volume in the left sidebar, ("Macintosh HD" unless you've renamed it). What is the hard drive capacity and how much space remains available on it? Repair permissions on it.
See if a little hard drive maintenance helps things out. -
Hey Guys i have a problem with my mac since last month and it wont boot up it freezes in a grey apple logo and and spinning gear any body know how to fix this?
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 the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
How to back up and restore your files
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.
How to use and troubleshoot FireWire target disk mode
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.
Before reconnecting 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 above for instructions.) 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 produces. Look for the line "Permissions repaired successfully" 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
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. -

Gray Screen, no apple logo, bread & butter mac, need help
While I was working on my Mac Pro the Apple Raid utility popped up with a warning that "2 serious events had occurred" One of the messages said something about the drive in carriage 2 had been removed... I closed Raid Utility and restarted (had to push power button until shutdown, then push again to start) only to keep getting a gray screen - no apple logo, nothing just a plain grayish-white screen. Could hear raid drives initiating, not sure if all were winding up. Tried resetting PRAM, SMC, etc... no luck. Tried booting to external drive (opt key), nothing, just a plain gray screen. dvd drive door wouldn't open, so manually opened it and put original install dvd in, restarted holding down C key, nothing, plain gray screen, won't boot to install dvd. Also tried booting to target disk mode, no deal, gray screen. RAID was configured 0 with one drive J+ and other three as one volume.
Thanks in advance for any help,
JohnOkay, I pulled all the drives and booted with bootable FW800 attached and with orig. install DVD loaded. Boot options screen popped up! I was also able to boot to Diagnostic on install dvd. So, I skipped the hardware test and installed drive 1 in bay one. The OS was on this drive as a J+, other 3 drives were RAID 0 volume. Again, attached FW800, left DVD loaded. This time the J+ drive in bay one showed up in the boot options... so I selected it and the MPro booted as normal. At this point I thought it wise to retrieve the events log from the RAID Utility. The following events occurred within seconds, in the following order:
"Drive 3:5000c50007da55af missing - Replace immediately or acknowledge loss of RAID set RS1 and associated volumes"
"Drive carrier 00:02 removed"
"Non-viable RAID set RS1 and all associated volumes are offline"
I assume this is telling me that Drive 3 (bay 3) failed. I think my next steps will be to
1. Leave the J+ OS drive (drive 1 / bay 1) in.
2. Insert drive 2 in bay 2 and try starting up
3. If that works, repeat 1 & 2 above with drives 3 and 4, using bay 2
I would deduce that if one of the drives causes the gray screen previously experienced it is the culprit. -
MacBook will not Shut Down or Restart
My MacBook will not shut down or restart from the apple menu, nor from any other dialog box that pops up, after an update, for instance. The only way I can turn it off/restart is by using the power button. I have tried archiving and installing OS X, but I am still having this problem. Does anybody know how to fix this?
Hi Henry,
Help here: http://docs.info.apple.com/article.html?artnum=303319
Second, make sure you have all your updates. Click the Apple logo in the Menu then click Software Updates.
Reset PRAM by holding option-command-P-R keys down during startup until you hear the chime at least three or four times.
Resetting the PRAM is a standard procedure for the problem you are experiencing.
Also, run Disk Utility and Repair Disk Permissions. DU is located here:
Applications/Utilities. Launch DU, select MacintoshHD in the panel on the left, then click Repair Disk Permissions. Quit DU and reboot.
If you need further assistance, please post back.

I disconnected my iPad unconsciously while it was updating ios 7.0.4 and it just stuck on that screen showing apple logo and a loading bar that just won't move on what to do now ????
It's not uncommon for it to not work the first time and sometimes, you have to try it a few times. Turn off your antivirus software and your firewall while you are trying to restore the iPad. Enable them again after you restore.
If that still won't work, post back with detailed information as to what exactly does happen as you go through the process. -
The macbook will not start. begins with "Deng", then the initial blank screen with flashing folder and question mark. Unfortunately, the DVD player is dead. I tried with a USB external drive and the installation disk but nothing happens (keys, C, D or N). I managed to get the mouse pointer on a blank screen by holding the alt key at startup.
My impression is that the disc is filled abnormally and can no longer boot. Probably jumped the permissions. I explain: the disk was almost full. Then my wife tried to connect to a site (German) images (art history) who was struggling to load the large amount of data downloaded. At that point the machine was stopped and forcibly turned off. From the day after is no longer divided.
I have no idea how to do it again and all attempts have failed. As a last test I can try with another mac connected and with the T key pressed (target). But I ask: can I connect with a USB-USB cable?Thank's for answer.
The internal DVD player is broken. I have an external DVD drive (USB). I have the install DVD for the OS. But the evidence that I did not have success. What evidence do you recommend? May you confirm that the USB connection is useless? We need a firewire cable crossed? -
My Macbook will not start up
I've had it about 5 years and around 3 years ago it started to go wrong with random shut downs so i took it into my local apple store and they replaced almost everything internally free under the special warranty i paid for.
since then its worked flawlessly, i dont use it often but did about a week ago to setup my new airport express (which wouldnt work from a pc)
now .. it wont start up
i't dosen't have a battery, that ended its serviceable life around a year ago with a life span of about 4 minutes so since then i've just run it plugged into the mains charger and has been absolutely fine.
when i plug the power adapter in the green light comes on and when i press the power button i can hear something inside whirring on start up (i suspect the HDD) and then the optical drive makes it usual sound ... but nothing else. there is no chime and the little white indicator does nothing also.
i tried unplugging everything and holding down the power button and that didnt do anything.
it's running Snow Leopard and literally has nothing on it, no files, no installed software, it only used from browsing the net so is pretty much empty except the OS.
PLEASE can someone help me find the problem and get my mac running againWell i never did try the command option p r combo, but have now and makes no difference.
and the macbook dosen't work again.
sometimes it sounds like it wants to boot, the HDD spins up and the optical drive makes a noise but no screen and no chime.
sometimes it does the above and then seems to keep rebooting as the optical drive keeps making the start up noise it does on boot about 5-6 times in a row.
but on all occasions ... still no boot and no screen.
