My daughter reset her IPod and after doing so the Ipod asked for a password. We do not have a serial number for the Ipod as it was used. The IPod is now disabled. How can I fix this?

You are going to need to go to: FORGOT APPLE ID to retrieve your iCloud/Apple ID. Once you know your ID, you can log onto Apple - My Apple ID and click on Reset Password to answer the Security Questions you will need to answer. If you don't remember the answers, you will have to contact Apple Support to have them reset: ACCOUNT SECURITY CONTACT NUMBERS

Regarding Mail: When I return to my computer after it has gone to sleep, my accounts go offline, and are always asking me for the password. THis is very annoying. How can I prevent this?

Back up all data.
Launch the Keychain Access application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Keychain Access in the icon grid.
Select the login keychain from the list on the left side of the Keychain Access window. If your default keychain has a different name, select that.
If the lock icon in the top left corner of the window shows that the keychain is locked, click to unlock it. You'll be prompted for the keychain password, which is the same as your login password, unless you've changed it.
Right-click or control-click the login entry in the list. From the menu that pops up, select Change Settings for Keychain "login". In the sheet that opens, uncheck both boxes, if not already unchecked.
From the menu bar, select
Keychain Access ▹ Preferences ▹ First Aid
If the box marked Keep login keychain unlocked is not checked, check it.
Select
Keychain Access ▹ Keychain First Aid
from the menu bar and repair the keychain. Quit Keychain Access.

Try this:
Placing your device into recovery (DFU-Device Firmware Upgrade) mode:
Follow these steps to place your iOS device into recovery mode. If your iOS device is already in recovery mode, you can proceed immediately to step 6.
   1. Disconnect the USB cable from the iPhone, iPad, or iPod touch, but leave the
       other end of the cable connected to your computer's USB port.
   2. Turn off the device: Press and hold the Sleep/Wake button for a few seconds
       until the red slider appears, then slide the slider. Wait for the device to turn off.
              * If you cannot turn off the device using the slider, press and hold the
                Sleep/Wake and Home buttons at the same time. When the device turns off,
                release the Sleep/Wake and Home buttons.
3. While pressing and holding the Home button, reconnect the USB cable to the
       device. The device should turn on. Note: If you see the battery charge warning,
       let the device charge for at least ten minutes to ensure that the battery has some
       charge, and then start with step 2 again.
4. Continue holding the Home button until you see the "Connect to iTunes" screen.
       When this screen appears you can release the Home button:
5. If necessary, open iTunes. You should see the following "recovery mode" alert:
6. Use iTunes to restore the device.
If you don't see the "Connect to iTunes" screen, try these steps again. If you see the "Connect to iTunes" screen but the device does not appear in iTunes, see this article and its related links.
Additional Information:
If you have a problem getting into recovery mode then try: RecBoot: Easy Way to Put iPhone into Recovery Mode.
Note: When using recovery mode, you can only restore the device. All user content on the device will be erased, but if you had previously synced with iTunes on this computer, you can restore from a previous backup. See this article for more information.

I have a new Macbook pro and can't recall the password I used with my Time capsule - How can I (ideally) retrieve or possibly change the time capsule password?

Remember security on a TC is an illusion.
Simply press the reset button for 1-2 sec.. you must not do too long .. it will then hard reset.. but soft reset will revert all passwords to default for 5min. ie TC password is now public.
Remember this the next time because anybody at all can change your passwords.
Once into the TC you can then open the view passwords if you wanted any weaker security. Click and open the TC.. and click on edit.. then go to the top menu..
Voila .. all your passwords in plain sight to any Tom Dick and Fred.

See if this helps...
Open Keychain Access in Utilities, use Keychain First Aid under the Keychain Menu item, then either check the Password under that item, change it, or delete it and start over.
Keychain Access asks for keychain "login" after changing login password...

If Keychain First Aid finds an issue that it cannot repair, or if you do not know your keychain password, you may need to reset your keychain.

Connect the iOS device to your computer and try to make a backup
iOS: How to back up
Then restore via iTunes. Place the iOS device in Recovery Mode if necessary to allow the restore.
If recovery mode does not work try DFU mode.
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
For how to restore:
iTunes: Restoring iOS software
To restore from backup see:
iOS: How to back up
If you restore from iCloud backup the apps will be automatically downloaded. If you restore from iTunes backup the apps and music have to be in the iTunes library since synced media like apps and music are not included in the backup of the iOS device that iTunes makes.
You can redownload iTunes purchases by:
Downloading past purchases from the App Store, iBookstore, and iTunes Store

HT5622 I think my granddaughter bought a $3.99 app after I put the password in for a free app. How can I find out what she purchased? Can I get credit for it? I just got an email from my credit card confirming the purchase.

I think my granddaughter bought a $3.99 app after I put the password in for a free app. I just got an email from my credit card confirming the purchase. How can I find out what she purchased? Can I get credit for it?

The password is good for 15 minutes to make purchases. You should receive a receipt in 24 to 48 hours for the purchases. There is a link to Report an issue. You could use that to start a conversation with iTunes Support about a refund.
Apple considers all sales final. But has been known to offer a one time refund. So the question is, do you want to use your one time refund on this purchase or one more expensive in the future?
