HT1758 Power failure in the middle of a software update and not the computer will not boot up. The computer just has a white screen with a grey apple and just loads non stop.

My iMac will not boot up after a software update. the screen is all whute will show a grey apple in the middle and will look like it is working but nothing happens; this can go on forever.
Does anyone have any suggestions?

Do you have a backup in the form of a bootable clone or Time Machine? Restore that and then try the update again.

Another option might be to download the standalone from Apple Downloads on another Mac and try installing it in Firewire Target Disk Mode to the Mac that was interrupted during the update.

My iMac won't boot up past the white screen with a grey apple and spinning icon

My iMac won't boot up past the white screen with a grey apple and spinning icon...please help!

command R did not result in anything different - still the white screen, etc. I do you Time Machine with and external hard drive, but I unplugged that. I have the installation DVD, but it doesn't seem to be reading it either.

When my phone is not plugged into the charger or computer, it will not turn on at all; even though it is not dead. When it's plugged into the computer, it will go to a white screen with a grey apple icon and then it will turn off again and repeat. IOS7

Try this step and if you cannot get your device into recovery mode there is a chance you have a hardware failure and you need to call apple to see what service options you have.

My Iphone 5 crashed yesterday, when i try to reboot it it comes up with the apple symbol but then some kind of script runs down from the top of the screen, then after a while it turns off again. Also sometimes it just has a white screen with pink lines

Went to restore it and it can't restore, got error 2002.
This is just great.

I have a mid-2011 iMac running Mavericks. When I click restart the computer goes to a white screen with a spinning circle and does not go any further until I hold down the power button to turn it off. What do I do?

Ok, sounds like the safe mode boot worked... You probably don't want to always be in safe mode though (some reduced functionality) so does it do a normal boot now? If not, you should then reboot into safe mode and run Disk Utility. Then select Macintosh HD on the left hand side, and click the Verify Disk button. If needed, it will ask you to Repair Disk. If there are errors found, Repair Disk again until there are none. Then try another normal boot and reply with result, wether good or bad.

I can't get the laptop to start. I get to the gray linen screen with a gray apple and stop. It will not ask for log in.

What do I do now?

Hold the shift key at boot time, then run through this list, did you install anything recently or perform a update of some third party software? Uninstall it.

Exporting slideshows results in file with only the first picture then a blank white screen with music. Apple bug or am I missing the obvious?

Usually when the phone shows just the white Apple logo, it indicates an issue with the system software that prevents the phone from finishing it's boot sequence. When this happens, you will need to restore the phone, which removes all data and replaces the system software with a fresh set.
Since the phone is not seen in iTunes when it's in this state, you will have to put it into DFU mode for iTunes to see it.
To put the phone in DFU mode:
- make sure the phone is connected to a computer with the current version of iTunes on it.
- hold the sleep/wake button and the home button simultaneously for 8 seconds.
- let go of the sleep/wake button and continue pressing the home button. The iTunes screen will show a short progress bar then show a dialog box stating that an iPod was detected that is in recovery mode.
-click OK
-click the Restore button in the middle of the iTunes page
After the restore the phone should be back up and running and you can sync your data back.

HT1553 I did the back up as instructed... Installed a larger hard drive and followed the restore instructions... Now I get a white screen with a folder icon and blinking question mark. When trying to set startup with new drive I get a bless tool error...

If you have installed a new hard drive , you will need to have formatted it in Disk Utility correctly. This may explain your problem.
Boot into your 10.6 Install disk again at the top menubar > Utilities > select Disk utility and in there select your new hard drive, and select the tab Erase and choose to make the format as Mac OS Extended Journaled. When that is finished look in the main window to make sure that the partition map scheme says GUID Partition Table.
Now go to the Restore tab and reinstall from your backup.

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

My iMac has a white screen with a flashing file folder with a question mark in the middle. What does that mean?

My iMac is completely unresponsive. Whenever I restart it, it's just a white screen with a flashing file folder with a question mark in the middle. What does this mean?

this means the mac cannot find the startup disc. which more times than not means you need a hdd replacement.
try starting holding the option key, then using utilities try to repair the disc.

Email not opening This is a sudden thing, Email had been working fine for two months then today would not stay open now it will not open at all. after trying to open mail I receive a white screen for a nano second and the app closes

Email not opening on my iPad2 This is a sudden thing, email had been working fine since purchasing the device then today would not stay open, now it will not open at all. After trying to open mail I receive a white screen for a nano second and the app closes.

Have you tried closing the Mail app completely ? From the home screen (i.e. not with Mail 'open' on-screen) double-click the home button to bring up the taskbar, then press and hold any of the apps on the taskbar for a couple of seconds or so until they start shaking, then press the '-' in the top left of the Mail app to close it, and touch any part of the screen above the taskbar so as to stop the shaking and close the taskbar.
If that doesn't work then you could try a reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

My MBP wouldn't start this morning, it was just stuck on white screen with grey logo and fan running. I replaced my magsafe power cord and resolved starting issue. Now I can't connect to internet and iTunes won't load??? Help?

MBP will start now, but won't connect to internet. I have full wi-fi signal. Also, when I try to launch iTunes, it just quits right away. Please help?

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.
