how to change admin apple ID on laptop

An Apple ID on the computer is only entered in the iCloud preferences panel. But there is no specific thing as an "admin" Apple ID, but there is an admin password and username.

JJust open settings and go to user accounts. Change the password for the admin account and delete the guest account.

This is not the same as your phone. The computer is not a single user device and doesn't hinge its function off the Apple ID and password.

Boy, you sure figured out how to mess that thing up. 😁 I would suggest, since it's new, that you just erase the drive and start over because at this point there isn't that much to lose. But before you go on it's important if you each have an iPhone of your own because you will need to set up two user accounts - one for you and one for your wife. Later, below, I will provide some helpful information on how to use two iDevices on one computer.

So, let's get to restoring the computer to its default state. I recommend this over trying to locate and change all the things you have configured. But if you would rather, then locate all the areas you configured - iTunes, Mail, user accounts, etc. Delete the Guest account you made.

Install OS X Using Internet Recovery

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 Internet Recovery HD:

Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.

Partition and Format the hard drive:

1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.

Reinstall OS X: Select Reinstall OS X and click on the Install button. Be sure to select the correct drive to use if you have more than one.

Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

This should restore the version of OS X originally pre-installed on the computer. That is what you want. The above process is going to take a while since it requires downloading a 5 GB file for installing OS X. Be patient.

Using More than One iDevice on the Same Computer

This applies mainly to couples who are adding another device and do not want their email, messages, etc. being duplicated on both devices. To begin read: How to use multiple iPhone, iPad, or iPod devices with one computer. You need to establish a separate Apple ID and password for whomever will use the new iDevice. See Apple - My Apple ID and Frequently asked questions about Apple ID. The easiest way is to do this on the computer using iTunes: iTunes- How to set up an Apple ID within iTunes.

On the computer create a new user account for the person with the new iDevice. This will be the user account that person will always use. He/She will no longer use the other user account. This way that person will have a separate iTunes Library. Note that once done you cannot "share" apps under a single Apple ID. Each of you must purchase your own apps under your own Apple ID. When you decide to split up like this one of you will need to re-purchase the apps that they want to use.

Start by transferring the new device(s) to a new account along with all your data. Save any photo stream photos that you want to keep to your camera roll (unless they are already in the camera roll) by opening your Photos app, tap on Albums icon at the bottom. Now, tap on My Photo Stream album; tap Select; tap on the photos you want to select;, tap the share icon (box with upward facing arrow) in the lower left corner; then tap Save to Camera Roll.

If you are syncing notes with iCloud that you want to keep then you need to open each of your notes and email them to yourself. Later you can copy and paste the text into new notes created in your new account.

Tap on Settings > iCloud > Delete Account (only deletes it from this device, not from iCloud; the person keeping the current account will not be affected,) provide the password to turn off Find My Phone and choose Keep on My iDevice when prompted. Sign in with a different Apple ID to create your new account. Choose Merge to upload your data.

Once you are on separate accounts, you can each go to icloud.com and delete the other person's data from your account.

I'll reiterate. If you and your wife want to use the same computer but have separate iDevices, then you need to each have separate Apple IDs and the computer needs to be set up with two user accounts - one for you and one for your wife. Since you already have one you need to create a new one for you wife to use with her Apple ID. If you don't have two Apple IDs, then each of you will end up with your mail, photos, contacts, etc. duplicated on each one's device. If that's OK with both of you, then you can stick to using one computer account and one iTunes Library and one Apple ID. If you make a new "joint" Apple ID then everything must be changed to use this new Apple ID. All your purchased items, however, are permanently tied to your current Apple ID and cannot be transferred to a new one. You will have to re-purchase everything under the new Apple ID.

Now, if you still want to use one joint Apple ID that is "new" then you will need to log out of the old Apple ID on all your devices, then log in with the new Apple ID. On the computer you need log out of iTunes then log into iTunes using the new Apple ID and setup a new account. This will also result in a new and different iTunes Library.
