my new imac has recently been displaying a red screen for a split second on startup, does this indicate a problem or not. I'ts my first mac so I know very little about it being a regular pc user.
My parents recently bought an iMac. Yesterday my mom was playing a game when the computer froze. Neither force quit or holding the power button was doing anything so in her frustration she unplugged the system. Today, after plugging in the system again, it won't turn on.
I press the power button on the side of the wireless keyboard and the green light on the keyboard turns on for about 3 sec and then starts flashing. No fans start up and the screen does nothing.
Information: iMac and Macbook Pro Mac OS X (10.6.3)
This is the image I get on my iMac 2.4 GHz Intel Core Duo OSX10.5.4. I have repaired permisions and removed all login items. Once I move the cursor or open up a window the screen clears behind the cursor or window etc... It freezes up at least once or twice a day...
I started up again and attached another screen, the image was normal on both screens. But alone the iMac still starts up with the pixelated screen.
I have an Intel IMAC, which is now out of warranty as I have had it for 16 months (and I was dumb enough not to get AppleCare). A few days back, my computer would not startup and everytime I hit the power button, I would hear some spinning noise but no chime from the iMAC. Yesterday, I tried it again and this time I heard the chime but the monitor did not start. I was then able to SSH into the MAC and see that it is indeed connected to the network and booted up, but the screen is still dead. Any ideas what I should do before the painful trip to the apple store ?
After connecting the imac to a new router the system hung completely up. After each input, e.g. opening preview or a browser, the coloured turning disc appeared and nothing happened anymore. Several restarts, also in safe mode, were unsuccessful. I could not switch to another user. Restart is only possible at all from installation disc but thereafter problem remains the same.
I don't think it's dead but something to do with the indexing of the HDD.
I can go into target firewire mode and i am backing up my data as we speak. However I do not have a big external HDD that i can back up everything so I have to pick and choose.
I have diskwarrior but it does not boot up. It says cannot find boot hdd or something and shows a No entry sign on the grey loading screen with the spinning gear.
I tried disk utility to repair the HDD but it says it tries three times and fails. Cannot locate the index file. I think this is my main problem here.
If i try and boot in verbose mode it shows this [URL] something message and repeats that it cannot locate the file. I dont even know what this is as i've never been to this website.
Anyway I can repair the index file and see if mac os x will boot up? Or you recommend a fresh install?
I just want to boot the mac once so i can look for some files because spotlight wont work since it says its trying to index the macintosh HD from firewire.
Yes I plugged in the block heater..... Tried to reset the SMC (apple's only advice) Tried to kick it into boot menu... no luck
managed to boot to Leopard install disk. backed into Disk Utility.... Verify System Disk produces: "Invalid B-tree node size...Disk Verify / Repair fail".
too bad too sad... no more information.
I don't know enough to know whether this is a SW failure or a drive failure, and my searches has led me here.
Also, my very first post in a forum, I read the rules and I hope I have found the right forum for this query.
Imac hard drive may have error because i get a blue screen on start up. I have started up using osx leapard disk but it looks like the only way to get hard drive going is to erase thecontest of the hard drive

When I turn on my computer there are 4 people to choose from to sign in. One is my son who has moved out and the other is my ex boyfriend and I do not want their start up/sign in icons on this computer anymore.(the last 2 are me and my daughter who uses the computer.) Where do I go to remove the people who will no longer me using my computer?
Also, when I went to post this question, there was iMac Intel and iMac PPC and I do not know what that means and which one i have. Can you tell me what they mean and how to find out which one I have so I know where to correctly post in the future?
my imac keeps freezing on the white boot up sceen where the apple logo usually appears. But the apple logo does not appear also the computer doesnt go beyond this point just fresses.
When I press the start button the screen goes on and I hear the chime but after 2 to 3 seconds the screen goes completely black. the fan in working the red light under the mouse is on. led # 1,2,3 are all on. I can't find my original system disk, so I inserted an original system disk from my macbook and tried pressing "C" at start up. But what ever I do the screen goes on for 2 or 3 second and after that goes black and stays black.
-Got the iMac refurbished in mid-2010 (2009 iMac i5) -Originally planned on mainly using Windows, so I partitioned the drive to 750gb for Windows and the rest for OSX
I eventually got fed-up with certain things about both Windows and certain limitations/glitches within Bootcamp itself and decided it was time to go OSX, and use the machine properly in all it's Apple glory.
I removed the 750gb of the Windows 7 partition, restoring the whole thing back to OSX. At this point, my computer seemed to be working fine still- OSX would boot up in about a minute or so, nothing that seemed out of the ordinary. After that, I still wanted a small partition with Windows 7; so I partitioned 100gb of my drive and proceeded to install Windows 7. During the Windows 7 installation, as had happened the first time I installed Windows 7 with Boot Camp, I got the "Black Screen" issue. If you are unfamiliar with the issue, see here:.......................
Turn on Mac goes to grey apple screen cog wheels spins but its stuck there tried control option p and r doesn't do anything tried turning it on while holding shift key to try and get it in safe mode but that does not work either.
I have not been able to startup my iMac for 3 days. When I turn it on all I get it is a white screen. After about 10 minutes a folder with Question mark inside apears in the middle of the screen and it just stays like this. I unplugged everything from the computer except for the mouse and keyboard. I had this computer since 2008 and never had a problem until now.Please help
My 27" iMac, running OS 10.6.8, has started running slowly when loading Apps and when running Safari. Also, when powered, on It has started stopping on the grey screen before the Apple logo displays. To get past this I must turn the Mac off and then back on.
I have a 2009-2010 27inch iMac with OSX and software fully updated.My Mac started shutting down or going into deep sleep when left on.I've tried rebooting, power long hold, checking cords etc.I've attempted the 5 second hold after disconnecting the power cord, plugging back in and start no luck.I hear a very small click inside when I long hold, sometimes a very faint spinning sound but nothing else.The fan came on once after a start attempt but nothing else happened. I can't seem to safe start because the screen remains black.
I am currently experiencing problems booting up my imac 17-inch, 1.6GHz (2004 model I think). When I hit the power button the machine starts but the screen rmains black and after about 3 mins of this, the fan goes into overdrive! The only way I can turn the computer on at the moment is to remove the casing and use the on switch located inside the the machine, although this is no guarantee it will work, sometimes it does but the majority of times it will be the same black screen as before. All I am waiting to hear is the part in the top corner (hard drive~?) to click into gear and then it's fine, and the machine seems to work perfectly. But this is not a solution and I fear it is only a matter of time before the machine just explodes altogether
I bought a Guardian MAXimus hard drive and it seemed to be working fine for the past few weeks. Now all of sudden when starting my Imac 27 I7 the grey screen takes a long time then it get stuck on the blue screen and stays like that. Some times after being on the blue screen it will goto the main page but it takes 3-5 min if it does. When it gets stuck, if I unplug the firewire from the back of the computer from the hard drive it boots up. Any thoughts, their tech support wants me to send the unit back with out doing any testing at home to see what the problem is, seems like a pain in the butt.
