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.
My 2007 iMac won't start up anymore -- I get the spinning "gears" and they flash on and off. It's a bit hard to explain, so I uploaded a video of what it's doing here: url...If anyone has any advice, please let me know.
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 ?
I know this is a fairly common subject matter but I have tried just about everything suggested but with no success. detailed below are my findings, I was wondering if anyone better qualified than me could suggest a diagnosis?
What does it do?
I hear the fans and hard drive and see the white/grey boot screen with the apple logo and spinning cog. The cog will spin for anything from 5 - 30 seconds before freezing. Some disk activity will continue for a short time afterwards before everything grinds to a halt?
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.
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.
The computer was my friends old one, which she gave to me as a gift. I'm trying to set a lock/password on it but it won't let me set one without the old password, which she doesn't know.
I have a 2010 iMac that won't start when I press the power button. No chime, no fan running, nothing. I tried unplugging it and plugging it into a different power source which made no difference. I made sure the power cord connections are good. We recently had an 8 hour power outage at my house and this is the first time I tried to power the iMac up since the power outage (it was working fine prior to the power outage). Of note, my husband's iMac started up fine after the power outage.
I just got the new 24 inch intel iMac yesterday and it was working fine until tonight. I installed Skype and as I was using it, the computer froze and said I had to restart. So I did that. It happened again, but this time, it wouldn't restart. It went grey and kept making loud beeping noises. I looked up what could cause this and it said that if the RAM was upgraded improperly this could occur. The problem is, I never upgraded the RAM. Its been working fine for the past day until now. What should I do?
I am running into an issue that the screen resolution of my imac keeps resetting to scaled 1600*900. I can use system preferences to change this to 1080p but every time I restart the computer it is back to 1600*900.
I have tried clearing the PRAM, but it has not worked.
I turned my iMac on (2008 model) but after 10 minutes it went black and beeped 3 times loudly, repeating at 5 second cycles. Shut it down by pressing the ON button for 5 sec. Restarted and all worked for a hour before repeating the same problem...screen and keyboard and touchpad all locked out....shut down with the ON button. On restart it gave me the 3 beeps every 5 sec with an ALL BLACK screen...no hard disk whirring, either. I don't know how to do cardiac massage on an iMac. Is it dead? Is it the processor? Is it the video card? Is it the hard disc?
My imac is around 4 years old and has been running both windows bootcamp and os x snow leopard for at least 3 years without any problems. My default operating system is mac and when I tried to turn it on this morning it gets stuck on the white screen with the grey apple icon and the loading icon spinning. Also a bar appears below this that I have never seen before. I have tried opening the mac in recovery mode but it does not respond and goes to the same logo screen.
I have tried holding the 'D' key down while the mac comes on and doing the apple hardware test but once the window pops up it does not complete the probing and appears to freeze just before its completion. I have also tried booting in safemode but the script stops at these commands:
-launch tl: Please convert the following to launchd: etc/mach_init.d/dashboardadvisory.plist
-launch_msg(): socket is not connected
However, the windows bootcamp is working fine and I can access my mac files from there.Also worth mentioning is that it is not a grey screen that appears on start up it is just the normal apple icon screen.
I have a G5 iMac - 2.1 ghz, 20", 250gb hd and 3gb ram, but it has been having problems starting up and it is also going to sleep midway through a task or at random times totally unprompted.
It now almost never starts up first time (I keep the iMac mains power lead always connected and the mains electricity supply turned on at all times now)- sometimes I will get the 'Start-up Chime' and then the cooling fans start spinning very loudly and then after a few seconds the iMac stops the start-up routine, but often when I try to start-up I don't even get the 'Start-up Chime' and I have to leave it for some time before trying again.
I can also now only get the iMac to run as a Firewire Target Disc by starting up with the T key held down and then using an old G4 (400mhz) Powerbook Titanium as the screen/keyboard by using the iMac HD as the startup disc for the Powerbook but this is obviously just a temporary work around.
I have also tried backing up all my data, and reinstalling the Mac OS X onto the iMac but the iMac still will not start-up normal and I still have to use it just as a Firewire HD.
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)
Running mid-2009 iMac with latest Mavericks 10.9.4.
DVD Player has been performing perfectly in Snow Leopard until this update to Mavericks.
I've tried resetting SMC/NVRAM. Reinstalled Mavericks 3 times. Tried dumping the plist too. That did nothing. I've re-set SMC/NVRAM...done the Permissions using Disc Utility.
I can get a DVD to load selecting the Recovery Mode StartUp disk. Then I reboot and the DVD plays fine using the DVD controls. But ejecting and trying it again - it won't play.
We had a pretty bad storm here last night and we had lost power. At the time my imac was on and obviously turned off when we lost power. A few moments after we lost power we regained power, but now my imac won't start. Any ideas of what have my happened and what I can do it try to fix it>
I have an aluminum Intel (2007) iMac and I have had it for two years now. I love my Mac and would never go back to a PC now, BUT (you knew that was coming) I have recently (unfortunately I don't know exactly when) developed a problem in that my iMac will not auto sleep. The screensaver will kick in OK, but it will not go to sleep on its own. I can put it to sleep from the menu manually, but not by the setting in System Preferences. I have reset the PRAM, and the SMC and neither of those changes have worked. Have any of you had this issue and solved it?
I have a mid 2007 24" iMac. It has been slowing down recently.I'm not clear as to the problem.Might it be due to the fact that it is running the latest operating system, 10.7.2, bloated, with only 4G of memory?
When ever I turn off my iMac (AL mid-2007 running 10.5) it seems like it hangs during shutdown. It takes about 60 seconds to shutdown and after about 30 seconds it starts to show. It looks like this, except it still shows my wallpaper... (This is just an image I found on the web). I am not sure why it is taking so long to shutdown lately... I don't remember it taking nearly this long in the past. Here is a photo of everything that is running during shutdown and it still does it. (I usually try to close out of apps before shutting down).
