System.log error after latest Security Update 2020-005 for Mojave from Sep 24th 2020

I installed the update a few days ago and, after a few days of hair-pulling, I finally took the advice I read from another member and just downloaded Mojave 10.14.6 and re-installed. All my files and apps were still there and it's working as it did before the update. Whew! A few lost days....

I guess now, I should just reinstall updates since Mojave was issued but NOT September update? Anyone know? I don't want to accept updates and have it just squeeze in the door with the others.

Those suggestions were to be done after re-installing Mojave. I was replying to sarahara.

Your options if 2020-005 is still installed are;

1. Restore from the Time Machine automatic local snapshot created by the update install. This has to be done within 24 hours or the snapshot gets deleted.

2. Restore from a Time Machine backup made before the install.

3. Re-install MacOS Mojave (a re-install will keep all your files and apps), then do what I suggested.

4. Upgrade to Catalina.

See sections 5 and 6 of this post if you need more detail on how to restore or re-install https://mrmacintosh.com/mojave-2020-005-security-update-causing-major-problems-updated/

Let me ask you, we’re are you seeing these system error reports? I will go look on my system if you tell me. I don’t remember how to find them.

Also I wonder if you have a problem playing music through iTunes?

Does Siri work for you?

Can you access the Sound preference pane in your System Preferences?

Can you create a new user and see it inside the User&Group pane of the System Preferences?

I can’t do anything of these things anymore since I installed that Security Update.

Hi again. I did all you suggested: installed original Mojave, installed update 2020 -004.

All went well, thank you very much.

Then I ran Software Update. All I find is - Safari 13.1.2 which I will install. But I can't find it in the list of updates in the Apple website. Could be I'm blind though.

QUESTION: there were no other updates. Is this because, when I re-installed Mojave, all updates since 2015 are automatically included? Seems logical to me. BUT then, why is this Safari 13.1.2 showing up as a found update? Why is the dreaded 005 not showing up?

Sorry, that was two questions. I hope they're the kind of questions that get answered here. I'm used to going merrily along with a problem-free iMac since 2007 so Ive been lulled into to being a naive user. (I bought a new one in 2016 but the old one - Tiger - still runs better....)

Looks like 2 updates came out tonight.

also, here is a great resource page

Yes, 2020-005 Security Update is back together with 10.14.6 Supplemental Update which apparently contains Safari 14.0 and fixes for all previous issues.

No reports of any problems yet but I'm going to wait until next week to install those updates.

Typing tmutil into the terminal does the same. Doesn't make be very confident about doing anything time machine related.

So, you fixed your problem? I installed last night and today my system is totally crippled. So you rebooted from Time Machine.... Did you lose data?

I used recovery mode and selected the day before 'snapshot' on the HD. Did not do a fresh install. I did run disk utility as well after and the HD is fine.

Thanks! I will do this.

Probably because the more recent update is in place, cannot install this older version.

Helpful comments. Peace restored after reinstalling Mojave 14 plus Security update 004. However, Catalina not really an option for Mac Pro 2012 (I've looked at DOS-Dudes but am very cautious).

The biggest question.... does the supplemental update fix damaged systems?

Don't mean to bother you, but do you know if the updates are safe? I've been holding off but now Apple wants to install them. I haven't yet.

Yes they're safe now, I installed them myself yesterday after waiting a week to see if there were any reports of problems.
