Maps stopped working. How can I fix it?

Question

I'm running Yosemite Version 10.10.1 on an iMac (21.5-inch, Mid 2011), Processor 2.5 GHz Intel Core i5, Memory 4 GB 1333 MHz DDR3. Maps has stopped working. It launches, then then displays a grid with a pin in it, and a spinning beach ball. It responds to nothing. I have force quit it numerous times, I restarted the computer several times, I downloaded and reinstalled Yosemite, and I shut down the computer overnight. I also trashed the p-list. I really like this program. How can I make it work again?

Answer 1

Back up all data before proceeding.
Step 1
From the menu bar, select
           ▹ System Preferences... ▹ Date & Time ▹ Time Zone
Check the box marked
          Set time zone automatically using current location
if it's not already checked. If the box is checked, uncheck it and then check it again. Test.
If the correct location and time zone aren't shown in the preference pane, then either Wi-Fi is turned off, or you're not within range of a network in the Location Services database. Under those conditions, the computer can't determine your location.

Step 2
Triple-click anywhere in the line below on this page to select it:
~/Library/Containers/com.apple.Maps
Right-click or control-click the line and select
         Services ▹ Reveal in Finder
from the contextual menu.* A Finder window should open with a folder named "com.apple.Maps" selected. Quit the application if it's running. Move the folder to the Desktop, leaving the window open. Relaunch the application and test. If there's no change, quit again and put the item you moved back where it was, overwriting the one that may have been created in its place. Otherwise, delete the folder you moved. The list of recent places displayed in Maps will be lost.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination  command-C. In the Finder, select
          Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
