Security Update 2019-003 10.13.6 failing at shutdown

Just had trouble again with the recent Security Update 2019-004 not completing the installation via the standard Software Update process, and so I again applied the procedure detailed in

https://davidsimpson.me/2018/11/14/fixing-failed-macox-10.13.6-security-update-2018-002/

and it got the update installed, worked like a charm on my 2010 27" iMac.

Have you done a PRAM reset, CMD+Option+p+r...

In fact, do 3 in a row, takes a bit of time.

Chose this step and it worked fine. Mac Pro late 2013 model.

The update 003 stalled again and again before at 38 min. And had to turn back to the old 002.

But... today took Google search again, (there can only be one winner!) found these instructions.

Did the steps via the Terminal app, via copy paste, to get it securely run and done.

Via restarts the installation progressed perfectly.

Hope it will help many this way.

If you Safe Boot does it shut down from Safe Mode?

I don't see anything in particular, except maybe Time Machine?

EtreCheck is a simple little app to display the important details of your system configuration and allow you to copy that information to the Clipboard. It is meant to be used with Apple Support Communities to help people help you with your Mac.

Pastebin is a good place to paste the whole report...

Workable but harder for me to work with...the Note tool on the bottom of this editor's toolbar, as shown in the image, to copy and paste the output from EtreCheck, blue arrow.

Solution to clear and reset a whole load of "stuff", and get the update installed:

The above works for update 2019-003 as well.

And your story?

Now this is a great example of what these forums are all about. I just found this post from a search and this solved my problem. I had "installed" this update about 3 times already on my 2010 iMac 27" and it would still keep showing up as an available update in Software Update.

After going through this checklist (oops, I forgot the step 5. Reboot in the middle) my system now shows the update as having been installed. Hopefully, it will stick this time. Thanks for the very helpful post. I wish I could award your post a "Problem Solved" gold star.

I have the same mid-2010 27" iMac and all security updates installed without a hitch which leads me to believe the issue must be software.

Ah, yes, our regular problem... from what we've done I can only imagine that the Firmware update got borked, in About this Max>System Report>Hardware, what is Boot Rom Version?

Boot ROM Version: 85.0.0.0.0

I was thinking maybe a reinstall... like a 3.57% chance.

I fear it's Firmware which is tightly controlled by Apple.

Oh wait... maybe some peripheral? Can you disconnect everything attached & try shutting down?

Just wondering about Sys Prefs>Energy Saver>Startup after a Power Failure setting?

Checked... gives an interesting: sleep prevented by backupd

Haha... need a repair or a patch to reinstal the shut down function.

Could be by way of reinstal of repair the OS via a download OS?

Strangely on my 21" 2010 iMac, this update installed just fine, as well as past updates. But, it seems that the 27" 2010 iMac, which basically has the same CPU/hard drive/RAM specs tends to require special efforts to get some of the Security Updates to completely install. Not sure what the issue is, but one time a representative from Apple asked me to send them a log from my computer to study the issue in more detail.

I got my 003 installed... and it won't shut down now, restarts. Whoeha!

Only with the button I can smother it to rest!

Must be the ghost of the Apple campus... it never shuts down for a nap... haunts for ever...

If you have a quick tip? I'd be very happy :-)

Thanks for your quick reply. Top!

Actually it shuts down completely, but restarts as if a restart command was given.

Used the shut down button... of course :-)

It happened yesterday... after installing 2019-003... and again today...

Just did a Alt Command PR 3 times... before my coffee break
