My Time Machine is not backing up. When I open it in system preferences, it shows it is turned off. It won't let me slide it to on.

 

Thank you.

    I would try these things:

    1. restart your computer and see if the problem is fixed

    2. Your time machine preference file may be corrupt.

    try this:

    1. hold down the option key

    2. in the finder, in the Go menu, go to Library

    3. in Library, open Preferences

    4. find this file in Preferences and drag it to the trash:

         com.apple.systempreferences.plist

    5. restart and see if the problem is fixed

     

    This will generate new system preference files with default settings so you will have to reenter your preferences.

    3. create a new test user account and see if the problem persists.

    Here is a general troubleshooting reference: Mac OS X: How to troubleshoot a software issue

    this should be enough to get you started.

    You did click the lock icon in the corner of the system preference pane, right?
