Put in the original DVD that came with your iMac and restart your computer by holding down the "C" key, once it has restarted go into utilities and repair your Mac hard drive, then select startup disk from the same menu and then restart your iMac.

I have a 21" iMac that only boots as far as a folder icon with a question mark in it. Anyone know what this means and how to fix it?

I have a 21" iMac that only boots as far as a folder icon with a question mark in it. Anyone know what this means and how to fix it?

It usually means your OS has corrupted files. You need to reinstall OS X.
If you are using Snow Leopard:
Reinstall OS X without erasing the drive
Do the following:
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 the Combo Updater for the version you prefer from support.apple.com/downloads/.
If you are using Lion:
Reinstalling Lion Without Erasing the Drive
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 the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
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 click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion and click on the Continue button.

24" iMac will only boot in safe mode

Here is the short version:
I have a 24" iMac Core 2 2.16 GHZ with Lion installed (has been for a long time). It will only boot successfully in safe mode. The AHT Extended tests do not report any problems. I have reset PRAM and SMC. Nothing helps. Normal boot process will get to the point where it switches from the Apple logo with spinning wheel to where it would normally switch the OSX GUI and login screen. Instead the screen is all white or gray. The exact same problem happens if I try to boot from an OSX Install DVD or USB and also my DiskWarrior DVD. Since safe mode works, my guess is that the problem is with the video card and the normal color depth that the Mac boots to. In Safe Mode it is in reduced colors.
Since safe mode works, I have all of my data backed up to an external drive. If I could boot from an install disk, I would have already wiped the disk and done a new install, but I cannot do this! I am assuming this is a hardware problem and given the age of this iMac I am out of luck. I ordered a new system last night, but if it is possible to get this one working again, I would like to be able to give it to a relative who could use it. So if anyone has any ideas, it would be appreciated.
Just slightly longer version:
Been using this system since 2007. Used to use it for work, now it is the home media hub where we sync our iOS devices. It has had Lion installed for probably a year now and has always worked great. A few weeks ago, it started locking up whenever my son was playing Minecraft. I would have to power off the system to get it back. I assumed it was a Java problem. I tried fixing disk permissions etc. but nothing solved it. Anyway, last week I was downloading App updates in iTunes when the system locked up again. The mouse would move around but I could not Force Quit anything or really do anything. So I had to power off the system. That is when the boot problems started. Since that happened, the system has not come back with a normal boot.
Thanks for any ideas/help. If someone thinks this is fixable, I can bring it to my local Apple service dealer. I do not want to pay them $100 just to have them tell me it cannot be fixed or needs a new logic board or something like that which would not be worth buying.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in safe mode.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
The commands may line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then either copy or drag it. The headings “Step 1” and so on are not part of the commands.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click the line of text below to select it. Copy the selected text to the Clipboard (command-C). Then click anywhere in the Terminal window and paste (command-V).
find /Sy*/L*/Ex* -type f -name Info.plist -exec sh -c '/usr/libexec/PlistBuddy -c "Print :CFBundleIdentifier" "$1" 2> /dev/null | egrep -qv "apple|Accusys|ArcMSR|ATTO|CalDigit|HighPoint|hp-fax|JMicron|print|SoftRAID|stex" && echo ${1%*.kext/*}.kext' {} {} \;
Post the lines of output (if any) that appear below what you just entered (the text, please, not a screenshot.) You can omit the final line ending in “$”.
Step 2
Repeat with this line:
ls -1A /e*/mach* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts 2> /dev/null
Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.
Step 3
osascript -e 'tell application "System Events" to get name of every login item' 2> /dev/null
Remember, these steps are all copy-and-paste — no typing. Also remember to post the output.
You can then quit Terminal.

IMac will only boot in Safemode; Gfx card failure?

My Specs:
iMac (24-inch, Early 2009)
2.93 GHz Intel Core 2 Duo
6 GB 1067 MHz DDR3
ATI Radeon HD 4850 512 MB
OS X Yosemite 10.10.1 (14B25)
The past few weeks I have not been able to startup my iMac regularly. Only way it boots is through Safemode. I cannot find my startup dads which was 10.6 I believe. I have attached links to two videos of what the display has been doing lately. I have reset the PRAM, run disk utility, disconnected all usb devices, etc. and nothing is working. I have managed to backup the entire HD to a time machine.
Video #1
https://www.youtube.com/watch?v=iGWrJqooJDg&feature=youtu.be
In this video; this is what initially was happening when it was running in normal mode. I noticed the lags, tears, processing slow and animations were very broken so I captured it on video. Few minutes later the computer froze up and tried restarting it many times.
Video #2
https://www.youtube.com/watch?v=fnMlRKcbyzw&feature=youtu.be
This is how Safemode operates at this time. The dock/finder animations are like this.
From what I have read I may be dealing with a failing video card (overheated)?

IMac G5 only starts up in Single-User Mode

I am using an iMac G5 with the lastest version of Tiger.
I was trying to make a my.cnf file for MySQL for it to start logging queries, however was having some trouble doing so. After restarting MySQL a few times it would not start up any more, so I tried restarting the computer.
After doing this Personal Web Sharing (httpd) would say that it was running although would not serve pages. So I tried restarting httpd which got it running properly, however I still had the same problem with MySQL, where it would not start running (the Preference pane would not respond when clicking "Start".)
So I tried restarting again. Now my iMac will only boot into single-user mode.
I read somewhere about modifying the boot-args, however have not had a chance to try it yet. I don't see why this would do anything however, as I'm not sure why that would have been changed in the first place?
Has anyone heard of a similar instance, which is possibly related to MySQL?
Thank you in advance for any help.

G5 iMac Mac OS X (10.4.7)

I solved this. I was able to boot up in verbose mode and note that a certain missing file '/etc/hostconfig' was mysteriously missing and causing an error at the boot-up. I was able to boot this mac up in Target Disk mode and copy the file into the /etc/ directory from a backup through another Mac and now it's working fine, thank G-d!

IMac Extreme + Boot Camp + Vista SP 1

Partitioned drive using boot camp and was able to successfully install Windows Vista w/ SP 1. System came up, inserted Leopard DVD to install drivers and ever since doing so, Windows will only boot into safe mode.
Have not tried seeing if Fusion can read the partition successfully or not.
Any ideas?

Update on this....
identical iMacs bought at the same time (when the debuted last year). Bootcamp install of Windows Vista w/ SP 1 works like a dream. Only change up from install directions (because of failure on other machine), was that post driver install, ran Apple updater and pulled down the boot camp updates. Worked with no issue..
On second machine (which assumed identical) not so lucky. Machine would only boot into safe mode after driver install. After getting into safe mode, disabled the ATI drivers and left it boot (successfully) back to normal mode running the standard Microsoft video drivers.
Download the ATI2600 drivers from ATI and installed. Video is back and golden, but without the dual monitor support that came with the Apple drivers.
Does anyone know if its possible to extract just the ATI drivers off the Leopard DVD and give that another go? I would really like to have the dual monitor support capabilities that I had on the first machine (24" iMac Extreme with a 19" Viewsonic monitor). Only difference between the two systems is the external monitor.
Thanks,
macfoo

IMac only boots in to Windows

Hi
My feonca got a copy of windows today and wanted me to install it for her. I created the partition using bootcamp setup the inserted the windows cd and rebooted. Competed the installation. Then I inserted the Leopard cd and ran the setup for the drivers. Some of the drivers would not install. It was then that I discovered the copy of windows is 64-bit and I cant get leopard back. The iMac only boots in to windows. What can I do to fix this.
thanks Dan

Holding down the option (or alt)-key during booting--as soon as you hear the apple chime--doesn't work?

PC networking to iMac booted in Vista, and in vista emulation-Small office

Re: Wireless and Wired Network: probably using a dlink 825 dual n band wireless router.
1. How is a typical Dell/ vistax64 networked to an imac booted in vista x64?
2. How is a typical Dell/ vistax64 networked to an imac running vista x64 in emulation?
*3. how are they configured to simultaneously synch business files and digital images, that will originate from the dell, in situation 1 & 2 above?
I (might be) stuck getting a Dell/vista 64 to acquire digital dental x-rays in the treatment room, bec the sensor mfg'er says the drivers won't work(!) on a Mac booted in Vista, either way. But since the PC imaging app and PC practice management software works fine either way, the iMac will rule the Front Desk. I'm still not convinced about the driver PC only spec! ..... Please help me get the sync'ed networking configured. Thanks!

IMac won't boot OsX Partition after Bootcamp install/uninstall.

Hello,
I have bought 2 late 2012 21.5 iMacs last year and have used both the same way. Here is what happened with one of them recently.
Fisrt af all I've installed bootcamp 1 year ago in both iMacs without issues and was ok so far, and was using exclusively Windows 7 partition. The trouble iMac started with some startup issues during boot/reboot (screen was frozen with green/grey horizontal lines), but worked fine after following manual start up.
Lately I've been trying to boot from OsX partition and it freezes in the apple logo every time.
I have already done the SMC / PRAM procedures, without success.
I have tried to download and do a fresh OsX install (Mountain Lion, Mavericks and Yosemite). Can't boot from Mavericks / Yosemite flash drive install (both freeze at apple logo - horizontal lines), and only had partial success with one Mountain Lion 10.8.5 flash drive install that booted all right and the first part of the installation process was ok, but after the initial reboot, it happened to freeze the same way before.
The iMac failed to boot in safe mode (stops booting at 25% and then freezes on apple logo), and show no issues with AHT tests.
I can boot in single user mode, but it reboots after a few seconds. I noticed some errors messages during this boot.
It fails to boot in verbose mode, showing a few lines of errors (images attached), and then freezes in a green horizontal line screen.
I can still boot from Bootcamp flash drive and Ubuntu Flash drive, and install both OS. The only issue is with OsX itself. I have used Gparted in Ubuntu to Format the hole partition to HFS+, and can't find any errors in hard drive tests.
I thought about buying a thunderbolt cable and try to do a Clone of my other iMac, but don't know if it will work.
Any other tests/suggestions about this issue?
Regards,

Fixed the problem with this setup
Of course this means i just lost 4GB.
Let me tell the full story.
In the beginning, long ago, once upon a time. My iMac had 2x2GB ram sticks which were in the two DIMM1 Banks. I then told myself "I WANT MORE RAM BECAUSE LOLZ". So i bought 2x4GB ram sticks. The two empty slots were Bank 0/DIMM0 and Bank 1/DIMM 0. and I added them in there. having done that, I booted OS X up, worked great, had 12GB, everything was shiny and beautiful. Soon after I wanted to try it out on windows. I restarted my computer and BAM the blinking cursor just sits there, being stubborn and all. I then told myself "holy balls, this new ram i got is bonkers" (them words, I blame the language filter). Then after giving it a little thought, i just asked myself if it was because I had ram from two different manufacturers. I removed my old ram, which has nice Samsung stickers on them, and booted it up on windows. Still had the same problem, I then decided that maybe this is all really mentally challenged so to win I had to think like a retard. I took my new ram and inserted it in the same slots where my old ram sticks were (DIMM1 Banks), booted windows up and IT WORKED.
I still hold all of my WHYs on this subject but I will keep messing around to see if I find a better solution than just leaving both DIMM0 banks empty

Bootcamp problem when booting win vista

hello guys
i have one small problem while booting with windows vist. i make a clean install with vista.
first i created bootcamp partition and then i boot with vista dvd and i formated the ''bootcamp'' partition and install vista. after restart and pressing the option key to select the vista boot the booting started with some errors. because is not possible to make screen shots on bootime i record a video and i uploaded to youtube so u can watch the errors.
does this happen on all macbooks with bootcamp/vista installation or the problem is on my macbook or the vista installation...?
http://www.youtube.com/watch?v=J7PrnQw-T_A
thanks

If Vista installed, and did an automatic restart after expanding and copying files to your hard drive, it should restart on its own into Vista until all the updates are applied. No need to use the Option key.
I didn't visit YouTube to try to see, other than what you have described.
As long as you formatted to NTFS and Vista accepted the partition (20-50GB is good number).
I would install Boot Camp from your OEM DVD from Apple either before doing any auto updates from Microsoft, or when it is all done. Either works. And add AV software like Norton AV 2009 (and yes, it is fine, unlike 2008 and before, and no need for any of the "Suites" with Vista, most get in the way and take over).
I have had trouble with Vista SP1 DVD though.

How can I transfer files from a 27" iMac which will only boot in safe mode?

My late 2009 27" imac is having issues and will only boot in safe mode. I have tried to transfer files to a new Imac using migration assistant but it wont let me. If I try booting the old Imac normally I just get a grey screen, I believe it is the video card failed and am waiting for a fix, but I would like to transfer files before the fix in case something goes wrong and I lose everything.
Any help would be great

Hello Myles, likely it is a Hardware problem.
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

Windows Vista and Windows 7 Only Boots to a black screen with a mouse cursor

Windows Vista and Windows 7 Only Boots to a black screen with a mouse cursor after I installed Mcafee Internet Security.
Hi I installed 1of 3 McAfee Internet Security protections on my HP laptop a few weeks ago with no issues. I Have a Dell XPS 420 desk top with Windows Vista operating
system, it’s never had any issues, until 2 nights ago I installed McAfee Internet Security (detected incompatible files and will remove) pc now only boots up to a black screen with a mouse cursor, it will show the windows logo and a hash symbol floating around
the screen. Now 2 weeks ago I installed the same program on my Dell all in one desk top with Windows 7, the same issue happen but that pc has no screen activity, I tried a back to factory reboot on this one, still black screen.

Hi,
Please install the compatible version of McAfee Internet Security:
http://home.mcafee.com/store/internet-security
if you have startup issue, you can boot into Safe Mode to uninstall the problematic software to go back into Windows.

If you can't boot from your installer DVD, then take it in for service.

PowerPC G5 iMac only booting up in Safe-mode - Help!

In July of 2005, I purchased my PowerPC G5 20" iMac, 2.0GHz, +260 GB harddrive and 2 GB of DDR SDRAM. It has been running so great that I even upgraded to Leopard OS 10.5.6 in June of 2011.
However in Nov. 2011, the computer would freeze upon start-up, and I would have to hold the power button to shut it down. After waiting a minute I would start it up and the OS came up ok. But each week I had to shut it down and restart a few times before it booted up ok. I ran the OS Disk Utility to repair permissions and it did not seem to make a difference. I also ran MacTuneUp 3.6.0 (purchased it in 2010), and there was also no difference.
Now I can ONLY boot into Safe-mode - Help!!!

Discovered something new!
I left my iPhone connected to the iMac, and when starting up the computer the iPhone started charging. When the screen froze (light blue shade, not black screen), the iPhone stopped charging. (no charge?).
BTW....my mouse always moves when in frozen state.
I also tried starting up (c-key) using OS 10.5.6 CD and computer also froze in light-blue screen. The computer tried to access the CD but then gave up. After leaving the computer for awhile the screen power saving mode was on (screen was black). When I moved the mouse the screen changed from black to light-blue screen. Boot CD did not work. No keyboard commands work. Only holding the power button will shut down the computer.
Help!!
