==Overview==
The SMC has roles in controlling thermal and power management, battery charging, video mode switching, [[Sleep mode|sleep and wake]], [[Hibernation (computing)|hibernation]], and [[Light-emitting diode|LED]] indicators. It also enables enforcement of the [[Mac OS X]] [[End-user license agreement|End User License]], allowing it to identify when it is running on non-Apple hardware.<ref>{{cite web|title=Interview with Andy Hall, Product Manager for Oracle VM VirtualBox|url=http://twit.tv/floss130}}</ref>
 
Apple releases occasional model-specific updates to SMC firmware which correct bugs and defects in the system.<ref>[http://support.apple.com/kb/index?page=search&q=SMC+update Search of SMC update information in Apple's knowledge base]</ref>
