How do I erase all the data on an old imac?

How do I erase all the data on an old imac, so I can safely sell/give it away without any personal information on it?

Boot with your original install discs, launch Disk Utility from the Utilities menu, select the HD, erase, reformat, and zero out the data. Once that's finished, reinstall the OS and on first boot quit the installer and shutdown the machine. Give the original discs to the new owner and when they start it up, they'll experience the first time Setup Assistant. Since it's not a new machine, there should be nothing associated with Lion or ML to muck things up.

I want to erase all the data I loaded onto my new macbook pro yosemite. I want to have it cleaned of all the data photos etc I have loaded so it is like a new computer again. I already have all this data on a hard drive so I don't need to back the data up.???

Install or Reinstall OS X from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
      left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
      the Security button and set the Zero Data option to one-pass. Click on
      the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
           because it is three times faster than wireless.

My friend borrowed my old iPhone 4. I wanted to erase all the data but I dont have a password and my friend doesnt know his password. How can I erase the data without using a password?

My friend borrowed my iPhone. I want to sell the iPhone, but first I have to erase all the data that belong too my friend. I don't know his password and he doesn't know either. Is it possible to erase the data without using a password?
thanks!

You need the password if it is iCloud locked you won't be able to activate the phone for use.
As long as he remembers his email, you can reset the password
If you forgot your Apple ID password
or Forgot Apple ID
https://iforgot.apple.com/appleid
If it is a lock screen password, you can do a restore.
Hold down power and home for 10 seconds and release power but keep holding down home. iTunes will say your phone is in recovery mode so you can restore it.

If my Ipad was stolen, I had erased all the data, but keep the Ipad on my account - nobody can use it without my permission?

If the iPad was running iOS 7, the thief/finder will not ever be able to use it.

Check the serial number (located on back/bottom) in this lost/stolen iPad database. However, most owners are not aware of this database and don’t enter the serial number.

Also do a search, using the serial number, on your local Craig’s List. Some users list the serial number of a stolen iPad to thwart the sale of a stolen device.

I have just purchased a new ipad2 to replace my old ipad. How do i sync all the data in my apps I am worried about losing my data?

iPad settings and data created and stored by a 3rd party party app along with app settings are included with the iPad's backup along with other data.
If you are syncing your iPad direct with iTunes on your computer via USB, the iPad's backup is updated as the first step during the iTunes sync process.
The first time you connect a new iPad or iOS device to iTunes that is used to sync with another iOS device, you are prompted to transfer the backup for the other iOS device to the new device. This is followed by a sync to transfer the same content from your computer that is on the old iPad to the new iPad such as music, movies, tv shows, 3rd party apps, photos, audio and print books, etc.
