Hi, i have a macbook air, but i want to upgrade to the new model. I want to sell my existing air, but can i wipe the memory clean of all existing content to sell it, but still update my new pc when it arrives?

Hi, i have an Air but want to upgrade to the new model. How do i wipe the memory clean of my existing Air so i can sell it, and ensure when i get my new PC it automatically assumes the existing settings? Any help appreciated...

First of all, as a rule you should have two backups before you do anything else. (most don't, and it's up to you).
I would have one backup done as a Time Machine backup on an external disk, which you will use to import all settings, data and apps to your new MBA via Setup Assistant on your very first boot of the new machine.
Second, I would have prepared, a bootable backup done via Carbon Copy Cloner or Super Duper on a second external disk. This you can use for unforseen problems that might be evident on the Time Machine backup (hey it happens).
After you have these two items in preparation, then use the original system disk or flash drive to reformat and reinstall the original operating system to the old machine, cleanly. After that, it is ready for sale. If the unit is not an SSD equipped MBA, you can perform a secure wiping of the disk when you perform the reformatting.
To reiterate.... You need a good Time Machine Backup as a source for you setting up the new Mac with Setup Assistant.

The update alerts are fake, and are intended to dupe you into installing malware or disclosing private information so that your identity can be stolen.
You might get the alerts when visiting a website that has been hacked. Don't visit the site again. If applicable, notify the site administrator of the problem, but don't send email to an unknown party.
If you get the alerts when visiting more than one well-known website, such as Google, YouTube, or Facebook, then they may be the result of an attack on your router that has caused you to get false results from looking up the addresses of Internet servers. Requests sent to those sites are redirected to a server controlled by the attacker. It's possible, but less likely, that the DNS server used by your ISP has been attacked.
Back up all data.
Unlock the Network preference pane, if necessary, by clicking the lock icon in the lower left corner and entering your password. Cllck Advanced, open the DNS tab, and change the server addresses to the following:
          8.8.8.8
          8.8.4.4
That's Google DNS. Click OK, then Apply.
In Safari, select
          Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
and confirm. If you’re using another browser, empty the cache. Test. If the fake update alerts stop, see below. Otherwise, ask for instructions.
The router's documentation should tell you how to reset it to the factory default state. Usually there's a pinhole switch somewhere in the back. It may be labeled "RESET." Insert the end of a straightened paper clip or a similar tool and press the button inside for perhaps 15 seconds, or as long as the instructions specify.
After resetting the router, quit the web browser and relaunch it while holding down the shift key. From the Safari menu bar, select
          Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
and confirm. Do the equivalent if you use another browser. Open the Downloads folder and delete anything you don't recognize.
Then go through the router's initial setup procedure. I can't be specific, because it's different for every model. The key points are these:
1. Don't allow the router to be administered from the WAN (Internet) port, if it has that option. Most do.
2. Set a strong password to protect the router's settings: at least ten random upper- and lower-case letters and digits. Don't use the default password or any other that could be guessed. Save the password in your keychain. Any password that you can remember is weak.
3. If the router is wireless, or if you have a wireless access point on the network, use "WPA 2 Personal" security and set a different strong password to protect the network. If the router or access point doesn't support WPA 2, it's obsolete and must be replaced.
During the time the router was compromised, you were redirected to bogus websites. If you ever connected to a secure site and got a warning from your browser that the identity of the server could not be verified, and you dismissed that warning in order to log in, assume that your credentials for the site have been stolen and that the attacker has control of the account. This warning also applies to all websites on which you saw the fake update alerts.
Check the router manufacturer's website for a firmware update.
If you downloaded and installed what you thought was a software update, ask for instructions.

Complete procedure for an Erase and Install of OSX Snow Leopard here Mac OS X v10.6 Snow Leopard: How to Erase and Install
I assume that you bought the OSX Lion 10.7 Upgrade at the Mac App Store.
If so, then you can't sell it with your MacBook, since the license is tied to your own AppleID and not to the MacBook.

I just sold my macbook air, how do I wipe it clean and delete everything?

Just sold my macbook air and need to wipe it clean....any help out there?

If you boot up whilst holding the option key and select your restore disk, you can erase it with disk utility and then install the OS again. This will wipe all info on it and leave it as if its new.
Hope this helps!

How do I wipe the disk clean and restart

I am giving my MacBook to a friend. I want to wipe the disk of all my information and then
set it up in her name as a user. ??

Put your install DVD into the optical drive and reboot. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option key until the Install Disk shows up). That will force your MacBook to boot from the install DVD in the optical drive.
When it does start up, you'll see a panel asking you to choose your language. Choose your language and press the Return key on your keyboard once. It will then present you with an Installation window.
Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it. You should see your hard drive in the left hand column along with your other drives. Click on the drive and select the Erase tab. Set the format value to Mac OS Extended (Journaled) and click the Erase button. After that has finished select the Partition tab. Type in a Name for your hard drive and select how many partitions you want from the Volume Scheme. The usual setting is one partition. Click on the Options button after you've selected a partition to make sure it's set for GUID. Then click the Apply button and after the Partitioning is done quit Disk Utility.
You can now follow the instructions on the install screen

How can I wipe the Launchpad clean and then repopulate it to my spec?

As I delete apps from my system they seem to linger on the LaunchPad. Some are easily removed by simply holding down the option key and clicking the 'x' that appears. But this does not apply to system apps or some others like Lightroom. How can I go about this?

This procedure will reset the state of LaunchPad to its default. Any customization that you did will be removed.
Back up all data before proceeding.
Triple-click anywhere in the line below on this page to select it:
~/Library/Application Support/Dock
Right-click or control-click the highlighted line and select
Services ▹ Open
from the contextual menu.* A folder should open. Inside it are one or more files with long names ending in ".db". Move those files to the Desktop, leaving the folder open. Log out, log back in, and test. If there's no change, put the files you moved back where they were, overwriting the ones that may have been created in their place. Then log out and in again. Otherwise, delete the files you moved.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.

How do i wipe sim card clean to give phone away

How do i erase sim card s that I can give phone away.

You can't erase the info on the SIM, and you'll need your SIM for your next phone, I guess.
To delete all the info on the phone, set it up as new device, without using any backup to restore from, explained in this article:
