General Troubleshooting
Update System Software
Important: Before you begin troubleshooting, ensure the correct version of Mac OS X is
installed, and check for and apply all the latest software and rmware updates.
Firmware is the name given to software that is written into memory circuits such as ash
memory, that will hold the software code indenitely, even when power is removed from the
hardware. Firmware on Intel Mac computers is designed to be updated if necessary by running
the Mac OS X Software Update check (available in the Apple () menu) while the computer
is connected to the Internet. For more information about rmware updates, refer to Apple
Technical article HT1557: About rmware updates for Intel-based Macs.

Unlike the Mid 2010 model, software install media does not come with the Mid 2011 computer.
To repair, restore, or reinstall Mac OS X and any bundled applications, refer to Knowledge Base
