[QUOTE="chscag, post: 1554188, member: 46727"] First thing to try is to reset the System Management Controller (SMC). Do this: Power down your iMac and then unplug it from the AC outlet. Let it set that way for around 10 minutes. Plug it back in, boot it back up and see if the problem has been fixed. Let us know. [/QUOTE]
