<p><b>New page</b></p><div>The '''System Management Controller''' ('''SMC''') is a subsystem of [[Intel]] [[Macintosh]] computers. It is similar in function to the older [[System Management Unit|SMU]] or [[Power Management Unit|PMU]] of PowerPC based Macintosh computers.<ref>{{cite web |title=HT2368: About the SMC Firmware Updates |url=http://support.apple.com:80/kb/HT2368?viewlocale=en_US |website=Official Apple Support |archiveurl=https://web.archive.org/web/20081223202919/http://support.apple.com/kb/HT2368?viewlocale=en_US |archivedate=2008-12-23 |url-status=dead }}</ref><ref>{{cite web |title=HT202040: About the SMC Firmware Updates |url=https://support.apple.com/en-us/HT202040 |website=Official Apple Support |publisher= |accessdate=2018-04-28 |archive-date=2021-05-19 |archive-url=https://web.archive.org/web/20210519004618/https://support.apple.com/en-us/HT202040 |url-status=live }}</ref><br />

==Overview==<br />
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 [[macOS]] [[End-user license agreement|End User License]], allowing macOS to identify when it is running on non-Apple hardware.<ref>{{cite podcast |host=[[Randal L.
