Apple fixes El Capitan kernel issue in supplemental security update

Last updated

Apple on Tuesday issued a supplemental security update for OS X 10.11.6, fixing a kernel issue for El Capitan users that causes affected Macs to 'occasionally become unresponsive.'

Available from the Mac App Store , as well as through Apple's support pages, the supplemental update is a free download weighing in at 623.9 megabytes, and can be used by any Mac running OS X 10.11.6 El Capitan with Security Update 2016-003 installed. Security Update 2016-003, originally released in December, has been reissued at the same time and measures 717 megabytes in size.

Aside from the kernel panic issue, little else is known about the contents of the update. Apple is expected to provide more details after it updates the official security updates page.

Users of macOS Sierra are still waiting for Apple to release the next update for the operating system, with the fourth and latest beta released last week.

I've been having problems with a 2008 iMac occasionally hanging at startup. Could this kernel issue be the cause of that?

I've had a weird issue with my nMP - sometimes when I'm using Firefox (and only Firefox) the mouse and then shortly afterwards the keyboard will stop working - the only recourse is to restart the computer. Media will keep playing.

Not sure if this is the same issue.

No. 

And then I remember I'm running Sierra. So, definitely No.
