Q: Wife and I have macbook, but one apple ID. I see her stuff on my computer and vice versa. How do I correct that

You create a new user account on the computer in her name along with her own Apple ID. The following is for using iDevices, but part of it applies in your situation as well.

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.

If you currently only have the one ID, then that should become your Apple/iTunes ID (more about that later)

If you have no other Apple IDs, then you will want to set up two new Apple IDs and iCloud accounts one for each of you

You would continue to use a single iTunes ID that you share, if you wish for future iTunes & App purchases.

Here's how it works:

The Apple/iCloud ID is the one that you each will have your own version of. This is the iD that you used to set up your personal iCloud account. On your device, you would sign this ID onto the following apps:

Messages

FaceTime

iCloud

On your Macs, you would sign this ID on in:

iCloud

Messages

Mail
FaceTime

The Apple/iTunes ID that you have been sharing for your purchases can continue to be used by both of your for that purpose alone. You will sign your Apple/iTunes ID on the folloing app on your devices:

iTunes & App Store

On your computers, you would sign your Apple/iTunes ID into the:

iTunes Store

Apps Store
