Hello there,

I'm running Macs Fan Control 1.4.3 on a 27-inch Mid 2011 iMac with OS X Yosemite version 10.10.5.

Since installing Apple security update 2016-004 (https://support.apple.com/en-ca/HT206903), my iMac fan will not stop when I put the computer to sleep. I'm fairly sure it has something to do with this security update, as it was running fine before, but just wondering if this is a known issue? I have checked with Apple and they haven't heard about this.

Thanks,
Jon

Hi,

How is it connected with Macs Fan Control?

PS. Try to reset SMC.

I'm not sure it is connected to Macs Fan Control, but it doesn't seem to be connected to Apple either, so I was just wondering if anyone else has had this issue.

I have reset SMC, PRAM, etc. to no avail.

I take it that I'm the only one then experiencing this?

I have a MacPro and after doing the security update my computer also will not go to sleep any longer. A soon as I turn off Macs Fan Control v 1.4.3 the computer sleeps without issue.

It is definitely tied to Macs Fan Control Version 1.4.3 as I can recreate this on other MacPros I own.

What if you don't quit MFC but simply put all fans to auto mode?
