How to reset an iMac?

My iMsc is frozen! I can't turn it off or reset it. There is a small multi color circle and a small window asking "the network "belkin.694" requires a WPA password" but it will not let me type the password.
How can I reset the computer? Please help!! Thank you!

Press and Hold the Power button until it shuts off. Then I would recommend you Reset the SMC and the PRAM:
Resetting the System Management Controller (SMC)
Resetting the SMC for Mac Pro, Intel-based iMac, Intel-based Mac mini, or Intel-based Xserve
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.
Resetting NVRAM / PRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
Hope this helps

How to reset an iMac if person deceased

i have a apple laptop powerbook g6 person is deceased. how do i get into the computer without throwing
away

Not necessarily. I have an iMac G4 which still can boot into the old Mac OS 9.
Anyway, some things you can find out. Your machine's age and the operating system it is capable of:
https://discussions.apple.com/docs/DOC-6413
Using a compatible operating system as a boot operating system externally is possible if you have the retail installer disc of that newer operating system, unless the open firmware password was set.
When the open firmware password is set, you may have to replace the PRAM battery to be able to bypass it. That's a separate battery from the one that enables it to work when you are off the external power source.

How to reset iMac before sell

i would like to sell my iMac but would like to know how to reset my iMac. And which dvd to install can i use both disk iMac applications install dvd and mac OS X install dvd?

Before you sell or give away your computer, in addition to the steps mentioned in this support article, take these steps:
1. Run Apple Diagnostics or the Apple Hardware Test. The buyer will do this (or he should), and you don't want to be surprised by the results.
2. Reset the PRAM and the SMC, which might contain personal information.
3. If you set a firmware password, remove it by running Firmware Password Utility in Recovery mode.
4. If you activated FileVault in OS X 10.7 or later, turn it off.
5. If you use Boot Camp, the partition must be deleted.
6. If you created any other data partitions on the internal drive, remove them in Disk Utility.
7. If the machine has an internal hard drive, erase the one remaining data partition with the option to zero out data. An SSD doesn't need to be zeroed.
You can't legally or practically transfer any software downloaded from the Mac App Store to the new owner of the machine, even if it was free. That includes OS X, so if you upgraded to OS X 10.7 or later, you must reinstall an older OS, either from the installation media, if applicable, or by starting up in Internet Recovery mode (option-command-R at the startup chime.) If you installed from physical media, deliver those to the new owner.
If you're selling the machine, or donating it in working order, and it originally shipped with OS X 10.4 or 10.5, then you have the option of installing either from the discs that came with it or from a retail Snow Leopard disc (which you must then transfer to the buyer.) The buyer should understand that if he doesn't get the original discs from you, he won't get the bundled iLife applications or the Apple Hardware Test. Replacements for the original discs can be ordered from Apple.
The new owner will have to redownload any software that came from the App Store, including OS X upgrades, under his or her Apple ID. If you ever updated the bundled iLife applications (Garage Band, iMovie, and iPhoto) through the App Store, you can't transfer those either. The buyer will have to purchase them.
Remove the machine from your list of registered products. If it's still covered by an AppleCare Protection Plan, transfer the coverage to the new owner by following the instructions in the AppleCare Terms and Conditions (under the heading "Transfer of Plan.")

How can I reset my iMac to the state it was in yesterday with Time Machine

Please help. I am trying to do something I thought was simple but I cant work out how to do it...
I need to reset my iMac to the state it was in yesterday evening using my Time Machine backup.
Yesterday I was on OSX 10.8 now I am on 10.6. The iMac was working fine yesterday.
Many thanks in anticipation...

This solved my problem! Great advice thanks! You have saved me from doing an unnecessary backup restore and re-upgrade which is what I was being advised to do elsewhere. Your fix took a matter of minutes! I cant thank you enough.
I still dont know how my 10 year old son and friends managed to do this in the first place as his account has parental controls and is restricted. I suppose they must have held a key on the keyboard during start-up and selected the wrong options!
Anyway, a lesson learned by all.
Thank you so much again for being inciteful with my question.

How to reset SMC in newest (Penryn) iMacs?

The most recent information I can find:
http://support.apple.com/kb/HT1543
says it applies to the late-2006 iMacs. Does anyone know for sure if the procedure is the same for later models -- or if it is different?

Sorry, but I thought you wanted the procedure for the laptops! Here's the document I think you need: Intel-based iMac, Intel-based Mac mini- How to reset the System Management Controller.

How do you reset your imac to original setting

pls Ive read the manuals and I dont get it pls help me try to reset my Imac to original settings

"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, or are running 10.7+, at least try it from the Safe Boot part onward.
If 10.7.0 or later...
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partitiion & use Disk Utility from there to erase & re-install the OS.

How can i factory reset my iMac?

hi, i am trying to factory reset my iMac to sell (as i've bought a MacBook) and from what i've see on the internet you need to hold cmd as it boots to go into the recovery partition so you can wipe the wipe drive and make it set up as a new Mac. My problem is that i use a wireless keyboard that comes with the iMac and this doesn't connect unitl after the initial start up?

Welcome to Apple Support Communities
You have to press the keys after hearing the startup chime until you see an Apple logo. The Apple Wireless Keyboard can be used during startup, but you have to press the keys after the startup chime.
After starting in Recovery, open Disk Utility and select Macintosh HD in the sidebar. Then, go to Erase tab and erase the drive. If you want that your files aren't recoverable, choose one of the secure erase options to erase the hard disk.
Finally, close Disk Utility and install OS X. When the installation finishes, turn off the computer. If you can't start up with the keyboard, buy a USB keyboard. The new owner will have to purchase the iLife apps if he/she wants to use them

How do I stop iMac from going to sleep automatically after 15minutes of inactivity

How do I stop imac from shutting down automatically after 15minutes of inactivity, trying to play music but the imac keeps going to sleep, tried changing power saving preferences to never shut down, never go to sleep, unticked put the hard disks to sleep, automatically reduce brightness, but still goes to sleep.

Try a PRAM/NVRAM reset.
Resetting NVRAM / PRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
After resetting NVRAM or PRAM, you may need to reconfigure your settings for speaker volume, screen resolution, startup disk selection, and time zone information. If issues persist, your Mac's logic board battery may need to be replaced. The logic board battery helps retain NVRAM/PRAM settings when your computer is shut down. You can take your Mac to a Mac Genius or Apple Authorized Service Provider to replace the battery on the logic board.

Factory reset latest imac...DVD?

I have the latest imac and I was wondering how to reset to factory settings, was it suppose to come with a DVD? If I need the DVD where would I go to get one ? The closest apple store is over three hours away. Thanks for all your help

No, Apple do not want you to distribute your family videos via DVDs, so iDVD has been withdrawn and is no longer available from Apple.
The current Apple thinking is that the entire world has access to fast broadband and wants to distribute home movies to friends and relatives via download (iCloud) rather than mailing them a DVD. The fact that in reality not all users do, has so far had no effect on this policy. If you scream and shout loudly enough down the phone Apple may send you a free copy of iDVD. That worked for some, but is now said to have been withdrawn by Apple. Also, you can complain bitterly here, perhaps suggesting that Apple could have provided a choice between using iCloud and burning DVDs:
http://www.apple.com/feedback/
Whilst Macs with a Superdrive continue to be able to burn video DVDs, the software for so doing, iDVD, is no longer included in the iLife bundle that comes with OS 10.7 Lion (which also omitted iWeb) or will come with OS 10.8 Mountain Lion. And it is no longer included in the iLife 11 from the online Apple Store: http://www.apple.com/ilife/. Your only solution is to look on Amazon or eBay and try to get an older version that includes iDVD.
However, the vastly more expensive FCPX can burn a DVD without iDVD or DVD Studio Pro involvement, but lack the themes etc of iDVD. Also, of course, there is Roxio Toast.
