Mid 2006 intel iMac wakes itself up

I have a 17" 1.83 Ghz dual core intel based imac. very recently, after upgrading to version 10.5.5, when I put my computer to sleep it immediately wakes itself up, and it will not go to sleep by itself. the screen will dim like it usually does before sleeping, but full sleep will never occur.
I have tried rebooting, as well as resetting the SMC. I have tried sleeping with no running applications. I have set a hot corner to sleep the display, and that works, but I cannot get thee computer to sleep. its pretty frustrating. any ideas?

whoops found the problem. My wireless USB mouse was waking it up for some reason. I guess Ill just unplug it when I put my comp to sleep from now on.

2006 Intel iMac with new Mac Mini?

I have a 2006 Intel iMac (MA200X/A) running Snow Leopard. It's finally gotten to the stage that it's running too slow to work on, so I was looking at the Mac Minis. Is it possible to use my iMac as a display for the Mac Mini?
The iMac only has mini-DVI so I was looking at the cables available and there's mini-DVI to either VGA or DVI, and then HDMI to VGA or DVI, would using the matching cables for each of those work?
(I can't really afford to spend at least twice as much buying a whole new iMac...)

No. The mini DVI port on the iMac doesn't support video in.

HT1349 Why would my intel imac wake at night unattended?

Why would my intel imac wake at night unattended?

Hey alexander1071,
I found an article that goes over some tips for when your computer won't stay in sleep mode:
If your Mac doesn’t go to sleep when you expect it to, or if it wakes up unexpectedly, you may need to change your sleep preferences or something may be waking your computer.
Make sure your computer’s sleep settings are set the way you want. In Energy Saver preferences, use the slider that controls the computer’s sleep.
Other users may be waking your computer remotely to use its shared resources. If you don’t want this to happen, open Energy Saver preferences and deselect “Wake for network access.”
Bluetooth devices can wake your computer. If you don’t want a Bluetooth keyboard or mouse to be able to wake the computer, open Bluetooth preferences, click Advanced, and then deselect “Allow Bluetooth devices to wake this computer.”
Key presses and mouse or trackpad clicks can wake your computer. If your computer wakes when you’re not present, something may be pressing the mouse button or keyboard.
Apps that access a disk can keep your computer from going to sleep. For example, iTunes accesses your disk to read the songs it plays, and DVD Player accesses the optical disc drive to play movies.
People using shared services on your computer can prevent it from sleeping. For example, they may be using a printer connected to your computer or accessing shared files stored on it. In Sharing preferences, turn off any services you don’t need to use by deselecting the On checkbox next to the service.
If Spotlight is indexing your hard disk, your computer won’t go to sleep. Click the Spotlight icon on the right side of the menu bar and check whether it says it’s indexing. Indexing your files can take several hours, depending on the number of files on your computer.
Malfunctioning USB, FireWire, and Thunderbolt devices may keep your computer from going to sleep. Disconnect those devices and see if your computer goes to sleep. If it does, reconnect each device, one at a time, until you find the one that’s malfunctioning. Contact that device’s manufacturer for more information.
Some PCI extension cards intentionally prevent a computer from going to sleep. Refer to the documentation that came with your card.

Setting up a 2011 intel imac 10.6.8 from an 2006 intel imac 10.4.11

setting up a 2011 intel imac 10.6.8 from an 2006 intel imac 10.4.11

I am not sure if my last post was actually posted.
In short, use Migration Assistant (MA) this is located in Applications - Utilities - MA on the 2011 machine. Then connect either the bootable clone backup EHD you created on the 2006 to the 2011 iMac and follow MA's on screen instrucitons. If you did not have a bootable clone backup then connect either a FireWire to Firewire cable between the two computers or a Firewire to Firewire 800 cable and run MA from the 2011 and follow the on-screen instructions.

IMac wakes itself up, then puts itself back to sleep

My iMac constantly wakes itself from sleep. The problem seems to have started around the time that I upgraded to Yosemite. If I leave the computer in sleep mode overnight, it will happen dozens of times throughout the night. The computer wakes up, but the monitor never comes on. I hear the hard drive spin up, I see my mouse’s LED turn on, then after a few seconds it goes back to sleep.
I have tried everything in this KB article (https://support.apple.com/en-gb/TS5357) with no luck. I have done SMC and PRAM resets with no luck. I’ve tried unplugging all USB devices prior to sleep in case one of them was waking the machine, with no luck. I have no Bluetooth devices, and Bluetooth is turned off. “Wake for network access” is turned off. I have no scheduled power or wake/sleep events. I have no file or device sharing enabled.
If I do a “wake reason” terminal command, I have page after page of the following message with varying timestamps: “Mar 28 11:45:20 iMac kernel[0] <Notice>: Wake reason: RTC (Alarm)” The info I’ve found about this says, “Real Time Clock Alarm, is generally from wake-on-demand services like when you schedule sleep and wake on a Mac via the Energy Saver control panel. It can also be from launchd setting, user applications, backups, and other scheduled events.” Again, I have no scheduled wake settings, “wake for network access” it off, and I have no applications that should be waking the computer.
I’m at my wits’ end with this problem. At this point, the only thing I can think to do is a full reinstallation of OS X, but I’d really rather not have to go that far. Any suggestions?
Specs:
iMac (20-inch, Mid 2007)
OS X 10.10.2
Processor: 2.4 GHz Intel Core 2 Duo
Memory: 4 GB 667 MHz DDR2 SDRAM
Graphics: ATI Radeon HD 2600 Pro 256 MB

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
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. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Early 2006 Intel iMac, does not boot, randomly crashes

Hi everyone,
So, I bought a used 2006 Core Duo Intel White iMac off of a friend earlier last year. The iMac has been running like a champ, I installed Snow Leopard on top of Leopard and it hasn't given me any problems until much recently.
I installed Bootcamp, secondary to the desire to play a little Team Fortress 2 and during the Bootcamp installation it actually randomly crashed. Weird, it's never actually done that, but since that time it would crash and would not power up for anywhere from half an hour to half a day. At first, it would only crash during Windows Vista, but now I found it crashing during OSX with the same problems powering up.
During the crashes, the computer will not respond to mashing on the power button, and sometimes, I will hear the high-pitched whine of the boot and the light in the bottom right of the iMac would go on and then crash at the gray screen. At other times, it will boot right into OSX and then crash with the same problems.
*Things I have tried:* Resetting the PRAM, resetting the PMC, deleting Windows Vista and removing the Bootcamp partition, Disk Utility on the few times the machine booted with a clean bill of health.
Results: Resetting the PMC seems to help rebooting, but does not prevent other crashes. Neither the PRAM reset or removing Windows Vista has helped with the problem.
*Things I will do:* Send the machine to Genius Bar and suck it up
Impressions: I strongly believe it to be a power supply/motherboard issue. I ran RAM tests and the RAM itself seems to not return any errors. If these are in fact the repairs I need, then it's beyond what I can actually repair on the machine, so to the Apple Store it will go.
I am however looking for any input into other people's problems like mine or any other thing I can do to test/bench the system (when it doesn't crash). I dig the machine and I thought I got a good deal, I am looking for any other insight you may provide. Also, if anyone has a good place to buy parts to test/fix Intel iMacs I am handy inside a computer, tinkered with PCs throughout my life. Thank you in advance!

Strange,
It’s beginning to look as though we have similar iMac characteristics. Here’s a couple of other things I did that you might try. Each of these seemed to improve the stability of my Mac.
1. One of the differences between a normal boot and a safe boot has to do with what fonts are loaded. Since my system seemed to run fine in “Safe Mode” it was suggested to me to run Font Book and verify all fonts. I did that and it found numerous (90+) minor font problems and 1 major problem. I deleted all fonts that showed any problem at all. I didn’t expect fonts to be a significant source of problems, but after doing this step and #2 and #3 below, my Mac began to behave better
2. Over time a lot of junk builds up on your Mac – caches, languages that are loaded with applications but not needed, logs, etc., etc. There are a lot of programs that will do clean up of these files. I really don’t know which ones are best, but I came across one called “CleanMyMac” and decided to buy and download it. When I ran it, it found a ton of stuff during its Scan which I then Removed.
3. Reset the SMC
4. Here’s an interesting one. I came across many comments about the importance of cleaning out the air in/out ports on your computer. I have a small compressor that I used to blow through the ports on my Mac. A not-insignificant cloud of dust came out of my Mac when I did that. Any dust sitting on components will act as insulation, retard heat dissipation, and cause those components to run hotter. After doing this, I swear, iStat began showing temps 10 deg F cooler than before.
5. I downloaded SMCFanControl. After a little trial and error, I set the minimum speeds as follows: Optical Drive fan at 1000rpm, Hard Drive fan at 1400rpm, and CPU fan at 1400rpm. This brought temps down another 10 deg. F at least.
I haven’t had a crash or hang of my system since.
Here’s the main temperature readings I’m seeing now:
CPU A: 91 deg. F (33 deg. C)
Graphics Processor: 93 deg. F (34 deg. C)
Hard Drive: 96 deg. F (36 deg. C)
Memory Controller: 93 deg. F (34 deg C)

IMac wakes itself up, WHY!?

I have an intel-based iMac and have noticed that it has a problem with waking itself up everytime it automatically goes to sleep. I have checked everything I can think of. The energy saver is set right with no weird schedule, I have unchecked any box I can find that says something about waking up the computer when an action happens. The only things that are plugged in are my printer, keyboard, and wireless mouse receiver. I have no idea why it is doing this.
Exactly what happens is after it has gone to sleep, I hear some small motor movement (must be the HD, or CD drive checking availability or something), and the fan runs for about a second. The screen does not come on, only all the noises present when a computer wakes up for real are heard. This is very weird I know, but I wonder if anyone else has this problem.

This might sound weird, but on both an iBook G4 and an Intel iMac I have experienced a wake from sleep when I turned on my desk lamp (fluorescent bulb) that was connected to the same power strip as the machines. I assume electrical line noise could trigger the computer to wake in some situations, or possibly frequency noise from the bulb? I never really tested other power strips or bulbs and just made sure to turn the light off for the night before I put the machines to sleep. FWIW.

Imac wakes itself

How do I stop my imac waking itself everynight at midnight?

This is discussed in some other places here, but I start to post the solution here:
My iMac also starts to wake up every night at 1 a.m. - even if I shut it down, it starts up at exactly this time. The different times (midnight, 4 a.m., etc.) seem to have something to do with time zones or daylight savings time settings. I searched here for an answer, and there was one that I tried (and only this one, so I can tell that this is really the solution for this annoying problem).
All I did was to activate the automatic startup in the "Energy saver" prefs, then *changed the time* (wich was per default at 0:00) to something else (I choosed 9 a.m., but everything else should work). Then I disabled the automatic startup again. And now my Mac sleeps well.
Nothing like "delete prefs" or "repair permissons", that was the only thing I did.
I hope this helps all other people here.
Thanks to the one who gave this hint!

My iMac wakes itself up!

My iMac G5 has started to wake itself up (from sleep mode) at 7:06 every morning and I can't figure out why.
The only account on the system is the administrator.
The only active applications are Finder and Dashboard.
I've checked in the Energy Saving preferences and there's no Schedule set to wake the Mac up.
The active Login items set in the Accounts preferences are: SpeechSynthesisServer, iTunesHelper, MicrosoftMouseHelper and Microsoft Database Daemon.
In the Network Preferences I've made sure that nothing can wake the computer from sleep.
I just can't think why it should wake up as it doesn't do anything when it wakes.
Any thoughts, cheers

I had this happen to my old iMac G3. Every morning I'd come down and it would be running even though I knew I had put it to sleep the night before. Then one day I was getting ready to use it and my wife turned on the hairdryer and it woke up the iMac. It seemed that the hairdryer outlet and the iMac shared the same circuit. There must've been just enough voltage change that it woke up the Mac.
UPS took care of it.

IMac wakes itself up.

Hello, can anyone help. I have an iMac running on all the up to date software, will be upgrading to Mountain Lion when it arrives. I have found that the iMac seems to be waking itself up through the night. I put it to sleep, and normally about 4 hours later, it will wake up, although the screen stays black. You can here the hard drive running for about 5 seconds, and then loudly clicks itself to sleep again. I have been running a WD back up hard drive, but only connect it once every 3 days or so. Any ideas?
Thanks Mel

I have a mid 2010 intel iMac, 3.2 Ghz i3 that won't turn on, any suggestions?

I attempted to turn my iMac on and nothing. Tried power button, mouse movement nothing. I unpluged the power chord to make sure all connections were good, repluged power chord and pressed power button and the iMac powered on with a very extended grey screen. As this is over 3 years old what should I check and or do. This machine has had the hard drive (1TB), optical superdrive, LCD panel & fan replaced under warranty/extended warrany. My 3 year extended warranty has expired so I am questing putting any money into this or saving for a new one? All help appreciated

I let the mac go into sleep mode and this morning it would not wake up. I unplugged the power cord, held the power button in for 20 seconds, replugged the power cord in and it booted normally. Ant suggestions?

Snow Leopard runs super slow on early 2006 (Intel) iMac

Hi. I need some advice please. I have an early 2006 iMac 20" that was running slow and I wanted to upgrade OS and main applications so I bought the SL box set. I backed up my data on a USB HDD and did a clean install, but now the system runs incredibly slowly. Genius at the Apple store ran diagnostics all day and found no problems with the HW and recommended I added another 1GB of RAM to existing 1GB. I did and system is still incredibly slow. I get the beach ball all the time and sometimes the system is completely unresponsive. Anyone else have performance issues with SL on this model iMac?
