IMac does not start-up after recovery screen.

My iMac (late 2008), does not continue to start-up.
After switch-0n, I get a grey screen with Apple loge, a 'busy' indicator and a 'progress bar', which fills slowly.
When the 'progress bar' is completed, the iMac switch-off.
When started again, the same repeats it self.
Any keyboard combination does not work.
What can I do..?
Kind regards

Hello Stephan
Start with booting up to the Recovery HD and then use Disk Utility to verify the hard drive. Check out the first article to go through those steps to sort you out. If for some reason that it checks out and you are still having issues booting up, then you will want to reinstall the operating system. I have provided the steps to reinstall OS X Mavericks, but the steps are the same for OS X Lion and Mountain Lion.
Also if you can somehow back up before you go through the troubleshooting to make sure that you have a safe copy of your date.

My iMac does not start up after Mavericks upgrade

Hi,
I have a 2010 27" iMac with OSX.6.8 (if I remember well). Yesterday, I made a backup on an external drive with Time Machine, I downloaded Mavericks, proceeded to installation and when it restarted it got stuck on the grey screen.
I've tried every procedure from the Apple support, nothing worked.
Please help. I'm not living close to an Apple store and I'd love to figure this out by myself.

Hi Philippe,
Has this iMac gone without AC power for extented periods?
If so likely the PRAM Battery is dead.
Couple of things to try...
Hold alt key at bootup, what boot options show up?
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.
Have you done a PRAM reset, CMD+Option+p+r...

In fact, do 3 in a row, takes a bit of time.

My imac does not start anymore (stops at the screen with the apple and a rotating circle). An idea what I could try to make it start again?

My Imac does not start anymore.
==> What I have already done:
1) I tried with the tigger dvd to reinstall. It didn't succeed.
2) Via the single mode, when starting I got the message "disk0s2: I/0 error" several times. After that I got "Root device is mounted read-only"
3) Nevertheless, I tried the "fsck -yf" function. After checking "Journal HFS Plus volume", "extends overflow file", "catalog file"... and invalid record count
==> /dev/rdisk0s2 (hfs) EXITED WITH SIGNAL 8
Can someone advices me? I red on the internet I could reformat the disk... loosing all the data I didn't backed up. How am I suppose to reformat?
Thanks in advance,
Fred

Restart the computer while holding down your mouse button which if you hold it down long enough (5 minutes at most) should eject the disk
If the disk still doesn't come out at that point then you need hardware evaluation;
contact Apple, contact an Apple Authorized Service Provider, or make an appointment with an Apple Retail Store.

My iMac does not start.

My iMac does not start. When I turn it on, it stays loading in the half and doesn't continue. Some days before I had updated my iMac to Yosemite 10.10. Everything was ok but yesterday I decided tu reboot it and when it was turning on this happened, it kept stuck at the middle of the bar. I have the latest model of MacBook Air '13.

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.

My iMac does not start up as usual. Start up disk is full message and I do not get normal desk top. Please can you help? Thanks

My iMac does not start up as usual. I now get a ' start up disk is full. You need to make space available on your start up disk by deleting files' message.
I am able to key my log on password however I just get the purple galaxy screen with no desktop.
If I try to use the keyboard I get a tone when pressing the keys.
Has worked perfectly well up until I got this dusk full message.
Can anyone help please. Thanks

Your going to have to follow the Data Recovery Efforts page here to be able to access your drive and remove files without booting the computer.
You can't open the iMac so you will need OS X booted from a external drive or via Firewire Target Disk Mode using another Mac.
https://discussions.apple.com/docs/DOC-3172
I would concentrate on Movies as this is a big source of large files to free up room.
Read Storage Drive here
https://discussions.apple.com/docs/DOC-3045
If you not handy with computers, your going to have to hire a local service or provide the info above to someone you know who can, it's not easy.

My imac does not start and asks for bootdisk

i bought a new imac and connected it with internet to upgrade the drivers. Power went off... and now imac does not start.
When it starts it asks for the boot disk and no boot disk came up with my mac.
Please help how can i reinstall mac.
thanks

None of the options work. I press the power on button keeping the option and R button pressed but the only option that appears is
First blank white screen appears as soon as i power on (option R is pressed) and then the following message
No bootable Device -- Insert boot disk and press any key
(Ethernet cable is connected but it does not go for internet recovery either)
No more activity.
Also if you can guide from where I can download OS X Lion for reinstalling it to the imac, please.
Does every mac come with a restore/bootable disk or not? We ordered two macs but did not get any disk with any of them.
Anxiously waiting for help....

IPhoto does not start up after upgrading

On my new iMac iPhoto does not start up after migrating. Upgrade from iPhoto 6/Snow Leopard > Lion 10.7.1 with iPhoto 9.1.5. When the conversion is finished I can see the new library, it works allright. And with packet-inspection (or how is that called in English) all maps & data seems to be OK; I can check the seperate pics.
But: iPhoto won't start up a second time (grey screen with infinite spinning wait cursor). The same thing is happening when I add a new library and drop in some pictures.
What can cause this problem?

Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Rebuild iPhoto Library Database from automatic backup.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one. .

imac does not start becouse cd i burn fast need help

andres:
Running Repair Disk from your install disk as suggested by neuroanatomist is the best first step. I have outlined the procedure in detail below, with suggestions for what to do if DU reports errors it cannot repair:
Repair Disk
Insert Installer disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.T Status of HDD at the bottom of right panel, and report if it says anything but Verified)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
If DU reports errors it cannot repair you will need to use a utility like Tech Tool Pro or Disk Warrior
What’s a kernel panic may help you identify the black screen you saw earlier. If it does, post back and let us know.
Good luck.

Please help me, my Imac does not start and make a terrible noise like an alert when try to start ,the Imac keep a grey screen when try to start and keep there.

Sounds like it is time to take it to an Apple Store or AASP to be serviced. You can also try troubleshooting using Apple's Gray screen appears during startup instructions.

Same thing happens when i click restart.
No difference when i run it in Safe mode. And it won't let me create a new profile either. Is there anyway else i can extract my bookmarks? This is driving me crazy!

Did the crash reporter send any crash reports? 
You can see the crash reports in this folder:
"C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Crash Reports"
See: http://kb.mozillazine.org/Breakpad
See also [[Firefox crashes when you open it]]
Create a new profile as a test to check if your current profile is causing the problems. 
See [[Basic Troubleshooting#Make_a_new_profile|Basic Troubleshooting: Make a new profile]] 
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" 
If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files) 
See http://kb.mozillazine.org/Transferring_data_to_a_new_profile_-_Firefox 
If that still causes the same problem then do a clean reinstall and remove the Firefox program folder.
* Download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
* Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
* Don't remove personal data when uninstalling.
* It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.

Xorg does not start (timeouts) with "no screens found"

After years of my system working correctly, this has been happening for the last ten days.
Many times - not all of them - xorg does not start, and I get greated with the standard console login prompt.
Checking in /var/log/ the xorg.0.log, it says that "no screens found".
I am using an nvidia VGA with nvidia driver 190.xx from extra.
I am using KDE, from inittab (not with kdm as a deamon).
Initial xorg.conf used to be:
Section "ServerFlags"
Option "AutoAddDevices" "False"
EndSection
Section "ServerLayout"
Identifier "Default Layout"
Screen "Default Screen"
InputDevice "Generic Keyboard"
InputDevice "Configured Mouse"
EndSection
Section "InputDevice"
Identifier "Generic Keyboard"
Driver "kbd"
Option "CoreKeyboard"
Option "XkbRules" "xorg"
Option "XkbModel" "pc105"
EndSection
Section "InputDevice"
Identifier "Configured Mouse"
Driver "mouse"
Option "CorePointer"
Option "Device" "/dev/input/mice"
Option "Protocol" "ExplorerPS/2"
Option "ZAxisMapping" "4 5"
Option "Emulate3Buttons" "true"
EndSection
Section "Monitor"
Identifier "My Monitor"
Option "DPMS" "True"
Option "DPI" "96 x 96"
EndSection
Section "Device"
Identifier "My Graphics Card"
Driver "nvidia"
VendorName "NVIDIA Corporation"
EndSection
Section "Screen"
Identifier "Default Screen"
Device "My Graphics Card"
Monitor "My Monitor"
DefaultDepth 24
SubSection "Display"

Option "DPI" "96 x 96"
Option "AddARGBGLXVisuals" "true"
Option "TripleBuffer" "true"
EndSection
Section "Extensions"
Option "Composite" "enable"
EndSection
Now I have trimmed it down to:
Section "Device"
Identifier "My Graphics Card"
Driver "nvidia"
EndSection
But the problem remains.
The problem started ten days ago.
The previous night I had updated the following packages (I provide a section of pacman.log):
[2010-01-21 20:35] upgraded acct (6.3.2-2 -> 6.5.1-1)

[2010-01-21 20:35] upgraded whois (4.7.36-1 -> 5.0.0-1)
So since nothing on xorg was updated, maybe the new coreutils is the more likely suspect?

Thank you
The reason you were asked if you rebooted is because installing the nvidia driver also installs a kernel module. That kernel module
needs to be installed in the running kernel, either by invoking "depmod nvidia" or rebooting, providing everything installed correctly. You
may need to put the module name in your modules section of rc.conf and then reboot.
The absence of that kernel module explains your error message of not finding that kernel module. :-)
iirc the .install already does the depmod
Note to TS: if you use virtualbox you can't use your hosts video card so you will have to use the vboxvideo driver. So read the wiki about virtualbox
