Reinstalling Mac OS X and Apple Applications
Under some circumstances, you may need to reinstall Mac OS X and Apple applications.

network. (To connect to a Wi-Fi network, follow the instructions on page 43.)

Click Install.
You can install Mac OS X without erasing the disk, which saves your existing files
and settings, or you can erase the disk first, which erases all your data and leaves the
computer ready for you to reinstall Mac OS X and Apple applications.
After installing Mac OS X, you can go to the Mac App Store and re-download your
Apple applications.
Important:
Apple recommends that you back up the data on the disk before restoring
software. Apple is not responsible for any lost data.
Restoring Your Computer to Its Factory Settings
When you restore your computer to its factory settings, everything on your computer
(your user accounts, network settings, and all of your files and folders) is deleted. Before
you restore, back up any files you want to keep by copying them to another disk.
Write down your network settings from Network preferences to make it easier to get
connected again after reinstalling Mac OS X.
