Here are some steps you can try to resolve the issue:
• From your desktop, click anywhere on a blank space on your desktop. Now you should see Finder listed near the Apple menu icon.
• From the Finder menu, click on Go, then Home from the drop-down menu. This will take you to your Home folder.
• Locate and open the Library folder
• Within Library folder look for the Preferences
folder and open it.
• Locate and remove to the Trash, these files:com.apple.Safari.plist
Once you have removed these files, then click the back button on your open Finder window. This will return you to the Library view.
• Locate and Trash the folder entitled Caches
Once you have done that, close all windows, click on the Apple menu icon located in the upper left corner of your screen and select Logout <username>
, so you can log out of your user account.
*Once you are logged out, simply log back in. This actions will restore all the files and folders you just trashed, with new copies of each of them.
*Now attempt to try the manual update once againManually Update TurboTax Deluxe 2011 for Mac
Let me know what the outcome is.
If this does not work. There is nothing more you can do, but wait for TurboTax to come with another update to address the current updates issue and Safari will not be part of the issue after all.
