Software :: New 24 Inch Intel IMac Won't Start?
Jun 22, 2009
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?

The new 27-inch iMac uses up to 365W vs 280W for the old 24-inch! (going by Apple's published max. power consumption numbers. I doubt they would lie because it isn't exactly favourable for them to put in falsely high numbers in an environmental report).
That means there's some extra beef behind the extra components. Perhaps the ATI 4670 is a bit overclocked and the 4850 runs a bit faster than the old iMacs? Admittedly that 2.8 GHz i7 is going to suck a fair bit of power - the recent 2.8 GHz i7 860 model runs at a 95W TDP, however, the quad core iMac isn't available until November. So it won't be using the i7 860, and my guess it is using another custom processor, something a bit more power efficient, somewhere in between the 55W TDP of the old iMacs and the 95W TDP of the i7 860.
The difference between the power consumption of the two computers is 85W. The old iMac had a 24-watt digital amplifier, this new one has two 17-watt amplifiers. That brings the delta down to 75W. Say the iMac's i7 processor has an 80W TDP. That now brings the delta down to 50W. The new display likely wouldn't increase power consumption because of the LED backlight.
I'm not sure if I'm missing much (OK, two extra RAM chips may use another few watts), but there is still a fairly massive 50W unaccounted for.
Just a bit of fat to chew on

I have a 27" iMac. Just recently, the screen has begun to randomly shut off. I then have to squeeze the power button, followed by a click of the mouse. This will bring me back to my password screen. Sometimes, that would be it, other times, it will do it repeatedly, for no reason, and then settle down.
Just for those of you who are bound to ask me about my Energy saving settings: Computer to sleep – Never. Display to sleep – 15 min.
It seems to me that this could be a hardware issue, but just incase any of you have had any experience of something similar, I thought I would ask.

Hello everyone, I'm currently looking to buy a 27 inch imac and can't decide whether to get a base i3 27 inch or a refurbished i5 quad core 27 inch. With the i3 I can get the student discount and qualify for the ipod, but the i5 is 23% off right now. Which should I get? Also is there a benefit of getting a 5 series graphics card over a 4 series graphics card?

I have 2 questions:1) I have a 2.GHz Core Duo CPU. I read that this model has a socketed CPU that can be replaced. Is this true?2) If yes, how fast can I go? Can I use the new Core i3 CPU?

early 2009 Intel iMac 24". OS 10.6.8.
Working in Excel today, I was highlighting groups of cells with color when the entire screen suddenly had a pale grey-green tint. Can still see colors beneath, but everything tinted (not just the Excel window, but the entire display). White, of course, is most dramatic. The Dell monitor beside it is fine.
I've recalibrated color a half dozen times (have always had to do that to get the Dell and iMac screens as similar as possible). It's impossible to get white on the Mac. Rebooted several times, including hard boot, zapped the PRam, ran Permissions Repair and Disk Repair from the startup CD. Installed Temperature Monitor to see if there's a heat problem, but I could not find normal temp values anywhere on the Web, so that was something of a bust. Temps attached below in case there's an educated set of eyes out there....
Ran some online tests, too, for color distortion, dead pixels, that kind of thing, but nothing reveled.
I've been all over the Web looking for some guidelines, but most posts at apple and elsewhere seem to focus on later-model iMacs with the yellow lower screen problem when new (It's not that) or panic screens of wild colors, stripes, and the like. This is just a grey-green tint that covers the entire screen, rendering whites grey-green and colors muddy.

I got a MacBook Pro back in April, my first Mac.
I love it so much. I'm really into video editing and HD video, but the problem is that my MBP is running out of harddrive space, and I'm longing for a bigger display and a better processor. (I have the 13" C2D). I'm going to pick up an iMac this Spring. But I wanted to know if I should stick to the Core i3 21.5, or spend more and go for the 27 inch.

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.

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.

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 am trying to decide which of these two 27 inch imacs I should buy:
27 inch 3.06 core 2 duo model
27 inch 3.2 I3 model
Is the 27 inch 3.2 ghz I3 model a better value in terms of increased computer and graphics performance and is it better to get the 2nd generation model because of prior issues (i.e. yellow tinge)?

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.

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.

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.
