When it comes to the operating system of the bitten apple, at this time OS X Yosemite, the first thing that we are asked when we start a computer from scratch is that we enter our Apple ID, which at the same time is the gateway to all our data from iCloud, Apple's cloud. The point is that on a Mac computer, unlike on an iOS device such as the iPhone or iPad, We can have a multi-user login so that each component of the family can have a different account.
Now, in each of the computer's user accounts, we can put a common Apple ID or a different one in each case, which is logical to be able to preserve the privacy of many aspects that are synchronized in the iCloud servers and are their own of each user. In this article we are going to teach you, whether you are new to the world of OS X or if you have been for a while but have never stopped to think about how disconnect your iCloud account of a computer user account and not leave a trace of your data.
As we have anticipated, the ideal is that each member of the family has an iCloud account, which will have 5 GB of space in the cloud for free to be able to save backup copies of devices, contacts in the calendar , the history data and Safari favorites, the notes and many other data specific to each user. That is why we do not see very logical that several different user accounts on a Mac computer have the same Apple ID assigned.
To disconnect a certain Apple ID account and with it all the iCloud services associated with that account, what we have to do is follow the following steps:
- We open System preferences that we can find them inside the Launchpad or we look for it in the Spotlight at the top right of the desktop.
- Within the System Preferences we are going to click on the icon iCloud, which is in the third row. You will see a window appear in which you specify the Apple ID with which you are connected and the data that is being synchronized and saved in the iCloud cloud.

- To disconnect the account and therefore delete all the data found in your iCloud account from that Mac, just click below the photo that appears on the left side of the window on Sign off.
- The system automatically asks you if you want your data to be deleted from the Mac, leaving all your data safe if you are not going to continue using that OS X user account.
