Start Up Issue-Gray Screen, Apple Logo And Cognition Wheel-Blue screen before start up at times but no longer starting up beyond gray screen and cognition wheel
Power button pressed.
Start up light okay
Chimes okay
Gray screen, apple logo and cognition wheel spinning and the loading bar underneath loading 1/10th of the way.
Loading bar doesnt load fully and then disappears.
Gray screen remains with apple logo and cognition wheel only.
No start up to desktop. Before start up to desk top which is not happening any more a blue screen appeared before the desktop appeared. When start up complete the ' Finder' had no responded and did not work' Multi coloured loading pointer continually turned. ' Network' could not be loaded in 'System Prefrences'.
Ive tried reading and following propts...Results NVRAM/PRAM - Logic board battery replacement. How much will this cost?
Hardware test - No problem found
Safe Boot - ' volume Machintosh HD could not be repaired.'
' Run time corruption detected on Machintosh HD device'
What do you suggest aside from taking it to a apple store?
Thanks Stephen
Lion or Snow Leopard? If Lion, boot into your Recovery partition (hold down the Command and R keys whilst booting) and use Disk Utility to verify and, if needed, repair the boot volume.
If Snow Leopard, use the installation disc and use Disk Utility in the same manner.

Gray screen, apple logo and spinning gear hang at start up
after a lengthy round of "bejeweled", i let my imac fall into screen saver mode. when i tried to log back in, i tapped the mouse and the imac flashed as it does when actuated outside a dialogue without clicking the okay button, and immediately returned to screen saver. i then manually shut down and restarted to the gray screen, apple logo and spinning gear hang. i then inserted the leopard install dvd, manually shut down and restarted pressing the option key and selected the install disc. it booted as usual. i selected the language preferred, used the utility drop down menu and selected DU, then selected the hard drive and verify permissions to reveal a pop up "Error: The underlying task reported failure on exit. Permissions verification complete." i immediately selected repair disc, and breathed a sigh of relief with the notification "appears to be ok". then utilities/start up disc/macintosh hd/restart. still get the hang. i have repeated this process several times, also resetting the PRAM as well to the infinite hang. as a matter of fact, the gear has been spinning the entire time creating this post. needless to say, i am truly at a loss. SOS!!!!!!! Please!!!!! SEND LAWYERS, GUNS AND MONEY!!!!
i have perused some of the threads posted per this topic and decided to attempt an "archive and install." i also have a 620gig acomdata external drive with close to a carbon copy of my internal. a few short minutes into the install, the imac reveals a pop up stating it cannot install some files on the hard drive, contact the software manufacturer or restart and try to install again. the internal drive is a 160gig with only about 60gigs of room, so i tried to archive and install to the acomdata instead as it has 180 gig of free space. i get the exact same dialogue once again. restart and a third attempt only archive and install will not highlight, only first time and/or erase and install. further, start up disc shows only the install disc and network as choices. so i attempt first time install on both drives and get the same pop up message again. DU recognizes both drives although verify/repair permissions does not highlight, but not start up disc.
i'm trying not to become frantic, but my patience is threadbare. i am in desperate need of sound advice as to what i need to do.
thanks again in advance,

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.
=======================================
Reinstall - 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.
Reinstall Mountain Lion or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is
three times faster than wireless. -

TS3148 my mackbook air starts up with a persistent grey screen, apple logo and spinning gear
my mackbook air starts up with a persistent grey screen, apple logo and a spinning gear. It will not show the login window
Press and hold the power button down to force a hardware shutdown (emergency use only!)
Next find the Shift key and hold it and press the power button, the machine will boot into Safe Mode.
Next backup your files to a external drive just in case.
Emergency backup procedure
Drag and drop copy your users file folders (music, pictures, documents etc) to a regular external powered drive as soon as possible.
Do not use, setup or trust only TimeMachine at this troubled time as it will copy corrupted data and we need just your users files safe just in case. TimeMachine cannot be used with a Windows PC.
Unmount and Disconnect all external drives once the backup process is completed.
Note:
If you have any over 4GB sized files, those won't copy to a standard formatted FAT32/MSDOS drive from the factory, if you need to save these 4GB+ files use another blank/empty drive and use Disk Utility to format it 1 Partition, Option: GUID, Format: OS X Extended Journaled (or the standard default one for older Mac's).
Mac's cannot copy to nor format a NTFS drive. ExFAT format to be used with a Windows machine must be right click formatted by Windows, not OS X (does it wrong) XP macines can install a free exFAT update from Microsoft. Vista-Win 8 can format exFAT.
Formatting a drive will erase all data on it.
Most commonly used backup methods
Your problem is likely due to a incompatible third part at boot kernel extension file that some program installed into OS X at some time.
If you can recall which programs you installed using your Admin password then that's a good place to start and update or uninstall those programs.
The next solution is a #8 Reinstall Just OS X + Software Update fully, this will replace OS X with a new copy, fix OS X if it's the cause and kick out ALL third party kext files out of OS X.
You also can manually drag and drop the third party kext files (if you know what they are) out of of the System/Library/Extensions folder and reboot.

G5 turns on but display stops at gray screen+apple logo
Can someone tell me why my G5 turns on but display stops at gray screen+apple logo. The keyboard and the superdrive not responding. After a minute the fans kick in and grow louder and faster...?? I tried a reset with the P and R but keyboard N/S. USB have power. I do get the start sound then the gray logo+screen.
Thanks for the help anyone!!
G5 dual 2G Mac OS X (10.3.9) 2G RAM, 23" displayI was getting a similar issue yesterday, stuck on the
grey screen, then the G5 turned into mini turbine
engine. I'm not sure what fixed it, i took out the
plastic wind deflector and noticed three leds next to
the RAM slots were lit up.. with some quick googling
bringing me back to apple's support pages, it turned
out the lights came up because the deflector shield
wasn't in place. Anyway myabe it was slightly out of
place, but that coupled with unplugging the power
cable for some moments seemed to help, and i was able
to get past the logo screen etc..
but i was still getting intermittent issues, with
startup and programs, and getting plenty of crashes.
So i did the Apple Hardware Test, and after 3hrs it
turned out my RAM was at fault. I recieved the
machine only a week back, since then i've added new
RAM, which was the exact same Samsung RAM that apple
use, though one stick didn't share the exact same
serial, it was still the same spec.. anyway i've
removed the pair of 1GB sticks for the time being,
and since doing so, i've got my mac running to its
full strength.. i just hope i can sort out this RAM
issue and not have blown my money.
Thanks for the help but I tried the cable thing etc and nothing so I reformated the disk (clean install and I'm back to normal now...so the RAMS were not the problem in my case.
Also, I'm glad I backed up all my stuff frequently therefore, no losses...

Mac SUDDENLY reboots continuously and displays apple logo that is half blue and half gray
I was surfing the web and my Mac goes black and reboots unexpectedly. I say OK, fine.....gray screen comes up then a Apple Logo that is half Blue and half gray appears with a graduated progress bar under the logo......it progresses half way then reboots and repeats-over and over again... I turned the unit off completely to cool off and give it a break.
I disconnected the ethernet cable and a few preipherals.
I am about to re-start in safe mode but wanted to bounce this here first.Well I took it to the GENIUS BAR and they have to replace the logic board which wont be in until Friday which *****....I am so glad i have APPLE CARE. is all I can say...I am also so very happy this isn't a WINDOWS BOX situation because then there wouldn't be TIME MACHINE. I may or may not have to restore from backup but it is there is I need it....so I will have to re-install all 3rd party software....but hopefully all the data will be there somewhere.....
thanks for everyone's help during moments of panic...

I resets my iphone without disabling touch ID lock, it restarts, apple logo appears, and it stays like that, it never starts till now, just the apple logo and stays that way, please give a solution???
Hi ahmedsgh,
I'm sorry to hear you are having issues with your iPhone. If it isn't responding or starting up past the Apple logo screen, you may find the troubleshooting steps outlined in the following article helpful, in particular this portion:
If your device gets stuck during startup
When starting up, you might see the Apple logo or a red or blue screen for a long time, or your device might restart again. Try these steps:
Make sure that you have iTunes 12 or later on your computer.
Put your device in recovery mode.
When you get the option to restore or update, select Update. This will reinstall iOS without erasing your data.
If your iPhone, iPad, or iPod touch doesn't respond or doesn't turn on - Apple Support

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) -
i've jail break Iphone 3GS. i tried to restore setting (erasing all data and media) without connecting to computer/itunes. When it starts it freezes by showing apple logo only. what is the solution. please help me out. Here i don't have iphone service center too.
Although not illegal, Apple discourages a user from modifying the iPhone OS in any manner, including "jailbreaking". Apple feels so strongly about this that discussing methods to assist a user trying to either jailbreak or "unjailbreak" an iPhone are prohibited.

Hello s0ha1b
If all you get is the Apple logo and it powering off, then the next step is to put your iPhone into recovery mode and then use iTunes to restore it. If you have a back up, then you can put that on there to once the restore is complete.
If you can't update or restore your iOS device

I searching my Facebook account when apple logo showed up then blue death scree then black screen after all white and black stripped screen . It happened for a few times the the phone went off and didn't work ever since . What was that ?
And how can it be solved ?Back up and restore your software via iTunes. If the problem continues, restore as a NEW device. If this solves it, that means there is some corruption in your backup file, or maybe it's one of your apps causing the trouble. If the problem is still there, you should take it to the Genius Bar at an Apple Store for evaluation.
For the charging problem:
Inspect the charging port area for dirt/debris/fluff build-up that may be preventing a good connection and use a wooden toothpick, soft clean toothbrush, or a can of compressed air to clean it. Also look for bent or broken pins. Try another cable and/or charger block (be sure to always use a genuine Apple certified brand) in a known good outlet. If you're using a USB port, try another port. If you're using a hub, try a direct connection. If you're using a USB port in the front of a desktop computer, try one in the back. If all these fail, make an appointment at your nearest Genius Bar to have the device evaluated.
