Hi there, 

I'm struggling with the removal of Cobook on my Mac. I want to get rid of it not due to the fact that it's a virus or something similar, but simply I have never used it and do not plan to do so. I have used to remove programs from Mac OS X before, nonetheless, I've noticed that the machine is running much slower than it used to before, so I suppose I'm doing something wrong. Could you please give me a piece of advice on how to remove Cobook on Mac OS and how to make it function as before?


As you have already mentioned, Cobook is NOT a virus. It's a legitimate application that is supposed to bring all your contacts to one place no matter where they may be stored. Nevertheless, many people were not satisfied by this tool and looked for the ways to get rid of Cobook on Mac OS X. If you want to find this out, you should carefully read this article and store every single detail in your mind because they will be useful for cleaning your Mac all the time.

However, before we go to the tutorial on how to uninstall Cobook on Mac OS X, we want to ask you one simple question. Do you know what are the differences between 'Removal' and 'Uninstalling' processes? Generally speaking the first one ('removing') is a primitive way to remove the programs by moving them to trash. Unfortunately, if you tend to remove programs this way, then be aware that you are leaving tens of unnecessary files on the Mac's system. Consequently, it may start exhibiting serious slowdowns one day. In order to prevent that, you should 'Uninstall' programs not 'Remove'. For that, you should not only drag the icon of the unnecessary program to the trash, but also find its leftover on various folders and perform their removal as well.

There are two ways how this can be done. Users who have much free time can easily uninstall Cobook on Mac manually (step-by-step guide will be given below). However, those who are not advanced users and do not show much will to learn much about Mac cleaning are advised to install [rev id=”MacKeeper”] (free to download) and launch it for the help.

How to uninstall Cobook on Mac OS X

If you seek to uninstall Cobook from Mac OS X, you have to perform the act of removal first. For that you need to:

  1. Open Applications folder;
  2. Click on the Cobook icon and hold it until it can be moved;
  3. Drag the application to Trash;
  4. Click Ctrl+Trash at once and then select Empty Trash.

However, this way you will neither uninstall Cobook ultimately nor increase your Mac's performance. If you remove programs this way all the time, your Mac might be turned into the storage of outdated and unnecessary files. If you want to eliminate the program from the system entirely, you have to find the whole bunch of data that is related to Cobook application. For that, check these folders because they may contain unnecessary data:

  • /Library/Preferences/
  • /Library/Application Support/

This process, of course, requires a lot of time. Therefore, if you want to save it and ensure that all unnecessary data is removed, we highly recommend uninstalling Cobook from Mac OS X automatically with the help of [rev id=”MacKeeper”].

Bottom line

To properly uninstall Cobook on Mac OS X, you should not only drag the application to the trash but also search for and remove any leftover files in various folders. If you prefer a manual approach, follow the step-by-step guide provided in the article. If these methods do not resolve the issue, consider seeking additional assistance.
