IMac-Green light nothing more....
I work for a large school district and am having the same issue with several iMac machines. I get a green light and nothing more, no chime, no HD activity, nothing...
Here is what I have done. Reset PMU, changed battery, swapped with known good RAM, Changed Keyboard and mouse to known good, replaced PAV, Logic, down converter board, power button, and hd data and power cable. Also tried known good CRT. I am having this issue on a few machines now and was wondering if anyone has seen this and how you resolved this issue. I have gone through the service manual troubleshooting steps and nothing seems to do the trick.
Please Help!
Hi,
I seem to be having a similar issue, over the last month my imac has been turning itself off, I've never witnessed this happening. But gradually over that same period it has become more difficult to turn the machine back on, it would turn on and begin to power up and then switch itself off.
Over the last week I have had to hold the power button down (causing I think the pram to be reset because it would chime when it came on). But as of last night I can no longer power the machine up, all that happens is the power light blinks for a second and then turns itself off. Similar or different? Any ideas? Is it the power supply. I haven't changed anything or installed anything recently. Luckily I made a back up on Sunday

I have been using my IMac without a problem when I left it and went back to enter the password the IMac did not see the keyboard. I have changed the batteries and the green light comes up on the keyboard and then starts to flash indicating it is looking for the IMac but nothing happens. I have tried another set of new batteries with the same result. Is there any known problems in this area. The IMac is 5 months old.
Thank you for any helpWhat operating system does your iMac have? (please always post your operating system to prevent confustion).
If it's pre-Lion you will have to set Mail up manually:
Entering iCloud email settings manually in Snow Leopard or Leopard

My A'Extreme sometimes won't connect to my MacBook Pro even if I have a green light on the device . I can unplug the ethernet cable and reconnect and it will work fine. all diagnostics say there is nothing wrong. Any ideas ?
This is more about your modem then anything. Sometimes you'll need to unplug and plug back in your modem. Consider it a glitch from the ISP or just the modem in general.
when I need to turn something off then on I try the modem first. This when I'm not doing any ware and tare to the device. -
I am no musician, but have owned an iMac now for around four years. During that time I have had Garageband installed. I have dipped in and out very occasionally as I would like nothing more than to be able to get my head around it just for my own amusement really. I would at least like to be able to record my electric guitar with loops and tracks etc, just try to be a bit creative and see what comes out. The problem that I have is that perhaps its me, but every time I try to get to grips with this software, I just can't seem to get my head around it, even to begin to do something. I have now recently downloaded 10.0.2 which is confusing in itself, as, as far as I can ascertain that is actually version 11, but I'm not even sure about that. I have also recently purchased a Rocksmith RealTone Cable to connect my guitar. I can sometimes get a sound come out, but nothing to brilliant. And every time I try to set something up, it just doesn't seem to work out. I end up hitting buttons and controls in the simple hope that I may hit the correct control in order to get some sort of result. But I'm kind of fumbling in the dark with this. I have trawled the Internet just trying to find either a good manual or video tutorials for absolute beginners, but there just simply doesn't seem to be anything of that nature out there and what there is appears always to be very sketchy and not particularly detailed in explaining anything properly, and so I always find myself seemingly jumping in with both feet and just struggling to try and find a foothold with this on how to really begin. It is so frustrating as I can see the fantastic potential of this software, but just can't understand how to use it properly. If there is anyone out there who may be able to offer me some advice with this, I would be most grateful indeed... Many Thanks.
I have now recently downloaded 10.0.2 which is confusing in itself, as, as far as I can ascertain that is actually version 11, but I'm not even sure about that.
Version 10.0.2 is the newest version and the successor to GarageBand '11 (version 6.0.5).
The '11 is referring to the iLife '11 suit of multimedia application - the older GarageBand was a part of this bundle.
Have a look at Edgar's graphical enhanced manuals, the explain very detailed how things work and why. You can buy them as iBooks from the iBook store or directly from the page:

Tried charging my 2009 MacBook Pro but the green light won't turn on and now my computer won't turn on (it was working right before I attempted to charge it!) what do I do????? Even tried using another charger I had for it and nothing. No green light. Computer turn on. Now what??? Help!
QUOTE: "No green light. Computer turn on."
What? so were you able to turn on the computer with the new plug? does it give you any other light? amber/orange light? -
Went through this step-by-step, but alas it did not solve the problem. For some reason I can download mail on my Macbook Pro and iPhone, but no my iMac. Connection Doctor shows all green lights. This started today when I was prompted to re-enter incoming mail server passwords. I re-entered passowrds yet again to make sure they were correct. Rebuilt the inBox. Connection Doctor continues to show all green lights, but am still unable to download mail to the inbox. Has anyone else ever run into this problem?
I have the exact same problem trying to use the Remote app on both my iPhone 3gs and iPad 2 with either my Mac or ATV2. My Remote app used to work on my phone - I can't recall if I ever actually used it with my iPad, but when I tried today, I got all the same results as you did (on both iPad, and then iPhone). I was using my ATV2 to play music from iTunes on my Mac and wanted to use the Remote app, but it would not connect to either device no matter what I did.

I recently transferred my internet service to another state.I have not yet moved my imac, just my pc laptop. I cannot get my airport extreme wireless router to work. The green light stays lit when everything is connected but I can't connect to the internet. Any suggestions?
I would recommend that you do the following as a minimum:
Power-down the modem, AirPort base station, and computer(s).
Power-up the modem; wait at least 10-15 minutes to allow it adequate time to initialize.
Power-up the AirPort base station; wait at least 5-10 minutes. Note: The AirPort's status light may continue to flash amber after it has intialized. That is because, there may be some additional configuration items necessary, like setting up wireless security, before the overall setup is completed to get a green status.
Power-up your computer(s).
If the above steps do not solve the problem, start over with step 1 above, but then perform the next steps between steps 1 & 2. above.
Disconnect the AirPort base station from the Internet broadband modem.
While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
After the base station resets, go ahead and power it back down.
Reconnect the AirPort base station to the Internet broadband modem. For the Extreme and Time Capsule, be sure to connect the cable to the base station's WAN (circle-of-dots) port.
Continue with step 2 in the first set of steps.
In this basic configuration, the AirPort base station will broadcast an unsecured wireless network with a Network Name (SSID) of Apple Network NNNNNN. Network clients, connected to the base station either by wire or wireless, should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options. Please post back your results. -
iMac will not load internet sites, despite having all green lights (strong WiFi signal etc) on the Network Diagnostics screen. in other words there is a strong
internet wifi signal going into the iMac but the machine does not connect to the internet. I OS 10.9.5. Other devices work fine with the same internet signal.iOS 10.9.5 does not exist.
iOS refers to the operating system on iPhones, iPads, and iPod Touch.
10.9.5 was never a version of a Classic operating system.
10.9.5 was a version of Mac OS X, and is 13 years newer than Classic.
Here are reasons for WiFi signal to fail even when they appear to be strong:

Your Mac may be too close to your WiFi router, in which case, it might be better to connect to it via an ethernet cable if it can't be moved. -
The Green Light is on, on my time capsule and airport but it will not back up all i get is the following message below please help.
The backup disk image “/Volumes/Data/iMac-D49A20D0AE94.sparsebundle” is already in use.Welcome to Apple Support Communities
First, restart your iMac and your Time Capsule. In most of the cases, this should solve the problem.
If it doesn't work, read > http://pondini.org/TM/C12.html -
My iMac doesn't start. Get the apple on the screen, nothing more happens. Any clues?
Rebooted - get the apple on the screen - but nothing more happens. What to do?
Take each of these steps that you haven't already tried. Stop when the problem is resolved.
To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. 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. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider. -

Green light does not flash any more
Hello guys can you please help me my green light does not flash any more and my blackberry has been slower than the word slow since ever the light is not flashing
Does the shuffle still play?
When it is connected to USB and the light is blinking orange, that mean DO NOT DISCONNECT - Eject shuffle in iTunes before physically disconnecting. If you do that (click the eject button in iTunes), but leave the shuffle connected to USB, the shuffle's light should become solid (not blinking). Solid orange light means shuffle is charging. If it's red, the shuffle may have a problem with charging. Does the SOLID light eventually become GREEN (battery fully charged)? -
my wireless mouse is not working at all. I have changed the batteries and still nothing, not even a flashing green light. I am using someone else's computer to ask these questions as I now can't use mine. Help!!!
I just had the same problem. And I found the solution, on Youtube.
The problem is that these ******** at apple designed the battery compartement, the distance between metal contacts too big.
That means the batteries plus or minus poles are not touching the corresponding contacts in the mouses battery compartement.
Most likely the battery doesn't get pushed up to touch the plus contacts.
I used a fingernail to push the battery up and tadaa, the green LED came on.
The guy in the Youtube video just put some folded aluminium foil under the minus poles for bridging the gap.
See here, "How to fix the Apple Magic Mouse!":
