MBP 最近打不开“桌面与屏幕保护程序”，显示“偏好设置错误 未能载入偏好设置面板‘桌面与屏幕保护程序’“，谁知道怎么解决吗？

试着修复一下权限吧

修复权限不行。

Here's the fix:

1) Close all windows & apps
2) Go to the System Library by selecting Finder, the hold the Option Key, then click on the Go tab at the top
3) Open the Application Support folder
4) Open the Dock folder
5) You should see desktoppicture.db in the Dock folder
6) Drag the desktoppicture.db to Trash
7) Reboot and you should be Good-To-Go

今天也遇到了和这个问题，在苹果官方论坛找到的解决方案。
