Early 2009 MacBook Pro failed Security Update 2018-003

My update to MacBook Pro running El Capitan 10.11.6 also failed on Security Update 2018-002 back in January. I restored my drive and did not attempt further updates until the recent release of Security Update 2018-003. This update caused my MacBook to hang during restart and never booted for over a day and a half. I am currently restoring from my back up drive.

Why is this happening? I realize that my hardware will not support Sierra or High Sierra but I would hope that security updates to El Capitan would still work.

Is there a solution or am I stuck?

MacBook Pro, OS X El Capitan (10.11.6)

Try installing the update in Safe Mode:

Use safe mode to isolate issues with your Mac - Apple Support

Also try downloading the update from here:

Download Security Update 2018-003 (El Capitan)

This solution, booting in safe mode and downloading the update appears to have worked. My MacBook seems to be up and operational.

It seems that I will have to remember to boot in safe mode from now on.

Many thanks. 🙂

You're welcome but you shouldn't have to. It may have been Safe Mode or the download itself since the one I posted comes from a different server. Hopefully, it will work as expected from now on.
