How do i disable messenger on the iMac but not my MacBook/iPhone I have an iPhone and MacBook that are my own and an iMac that I share with my fiancé. I have it set up currently so that my text messages come to my phone and both computers.

As this can be annoying when she is using the home computer and I am not (getting my random texts), how do I disable Messages on the iMac but not my MacBook/iPhone?
Assuming you mean the Messages app, all you need to do is sign out of it on the iMac.

To do this:


Launch the Messages app on the iMac
Go to Messages menu > Preferences
Select the Accounts icon
Click on your account (in the left-hand column)
Click on the Sign Out button (on the right-hand side)


When you exit the Messages app it will no longer receive your messages.
