Problem, Meet Solution

m

Restart your computer while holding down the Command key (x) and R key.

Some utilities in the Mac OS X Utilities pane require access to the Internet and the
Mac App Store. You may need to make sure your computer is connected to the
Internet via your Ethernet or Wi-Fi network.

Choose a network from the Wi-Fi status menu in the upper-right corner of the screen.

If necessary, type the network password.

To join a closed network, choose Join Other Network. Enter the network’s name
and password.

If you have a problem with your computer, or if you start your computer and see the
Mac OS X Utilities pane, you may need to repair your computer’s disk.

Select Disk Utility in the Mac OS X Utilities pane and click Continue.

Select the disk or partition in the list on the left, and then click the First Aid tab.

Click Repair Disk.

If Disk Utility can’t repair the disk, back up as much of your information as possible,
and then follow the instructions in “Reinstalling Mac OS X and Apple Applications” on
page 89.

For information about Disk Utility and its options, see Help Center, or open Disk Utility
(in the Utilities folder in Launchpad) and choose Help > Disk Utility Help.
