myang 但是这个操作步骤,实在是在正常的苹果操作系统内的操作吧,在启动 u 盘里,哪里有 system Preference ?
大兄弟是不是给错链接了?
Quit the OS X Mavericks installer.
Choose "System Preferences" from the Apple menu ().
Click the "Date & Time" icon in the System Preferences window.
Click the "Date & Time" tab in the System Preferences pane that appears.
If the padlock in the lower left is locked, click it and enter an administrator name and password when prompted.
Make sure the "Set date and time automatically" checkbox is selected and the appropriate region is chosen in the field to the right of the checkbox.
Alternatively, manually set the date and time to an accurate setting (for example, the date should be set later than Oct 1, 2013).
