I've got serious problem with latest security update on my 13' MacBook Pro Retina (Early 2015). After update my Mac heats up and throttle as hell. I reinstalled Mac OS Sierra from scratch, changed thermal paste on CPU twice, nothing helped. I can have ~80 celsius on my CPU, when I'm only browsing the net on Safari. It's hard to use any powerful applications, because it can heat up to even ~100 celsius and above. Please help, what can I do? Did anyone had the same problem? Thank you in advance P.S. I can't upgrade my OS to newest version due to my health problems. So I have to stay with Mac OS Sierra.

Untangling Confusion:

The original "Security Update 2019-004 (High Sierra & Sierra)" contained a bug that affected Sleep mode on a few recent Mac models. Without explanation, Apple pulled the update for several days. Then, without explanation, Apple made the update available again with modifications that removed the Sleep bug.

If you have questions about whether you have the correct version installed, simply download and install this latest version. For details, please read:
"Apple has released High Sierra and Sierra Security Updates 2019-004 again"

If you have an older Mac, you are stuck on macOS 10.13.6. A number of people have had problems installing Security Update 2019-003 10.13.6, where on shutdown the Mac hangs at a black screen with just the cursor visible, requiring a hard reset that doesn't complete the installation. Rinse and repeat, but no success.

Quick solution to enable successful shutdown, but does not install the Update:
Delete the files that trigger the patch installation on shutdown

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

The above works for update 2019-003 as well.

I have High Sierra 10.13.6. When I try to update with this download, it comes up with "ALERT. This update requires macOS version 10.12". Yet this download is supposed to be for my OS as well? I had previously tried to update in the App Store, but every time I restart my screen goes black apart from my mouse pointer which works perfectly, but nothing happens, it stalls. The only way to do anything is to power off and on again and it loads fine. But as soon as you do a restart, the same thing happens. Help!

This is a seriously buggy POS (for reference, this was on High Sierra). Installed it, seemed to go fine, restarted after the updated, seemed to go fine, shut down my laptop and went to another location, restarted my comuter and it would NOT boot up (said there was something wrong with the Mac OS installation). I had to start without system extensions, open the App Store, and install it AGAIN. There was NO warning about problems with the initial install. Can't you do better, Apple??

You might want to look at my replies to Scion777 below. That could have something to do with your experience. Although I didn't have any trouble after downloading/applying a few days ago, I am being prompted to re-install the update as of today.

I'm on High Sierra 10.13.6

I download and applied this DMG a couple of days ago from the URL mentioned here. The checksum matches the one shown here. Machine rebooted itself as is typical for this kind of update. Today, however, App Store indicates the update needs to be applied, despite the fact that the update shows under Updates Installed In The Last 30 days. However, for that entry, there's a lot of missing information:

Security Update 2019-002
Version
Installed March 27, 2019

The version field is empty, as is the detailed description that's typically shown in the column to the right. I've don't recall seeing an update entry with that information missing before.

Anyone else have this experience?

My guess, based upon the fact that Apple had a December date on the download page, and the fact that this update was not immediately available through the App Store for High Sierra until today is that the download mentioned here may not have been the same as the actual release version that's showing up today.

It appears that App Store has already finished downloading the update, and is ready to apply and restart. I would love to find that download to compare the checksums. I've already looked in $TMPDIR../C/com.apple.appstore/, and it's not there.

Does anyone know where the download might be?

Well, it appears I was correct in my assessment. The file at the URL for High Sierra is NOT the same file as that was there on 3/27 . I just downloaded it again and compared the two files. Same name. Different size.
The SHA-256 hash for the current file is 27765011d7028a643516e5ac106033b6340ee00f261f8e85ae444653d5a17211
For those of us who installed the earlier file, the missing meta data is probably the reason this happened - considering the file size is minimally different. That explains everything including the update re-appearing in the App Store Updates.

And Mojave doesn’t get a security update, instead they get 10.14.3

No trace of an Apple Security Update 2018-006 for OS X 10.11.6 anywhere — and I bet the 004 will be the last forever — so why keep on calling this page "For macOS 10.12.6 and OS X 10.11.6"? I've just lost time trying to find it... :-/

"Will Apple Security Update work good <sic> on macOS 10.13.4?" I'm guessing it won't. Nice work, MacUpdate.

Each version of macOS has its own version of Apple Security Update. Updates will refused to install on the wrong version of macOS. IOW: Yes, the version for 10.13.4 will work good on 10.13.4. If you haven't installed it by now, get to it ASAP.

My comment concerns MacUpdate's description of this entry - "For macOS 10.12.6 and OS X 10.11.6". So no, it won't work "good" for macOS 10.13.4.

If you are using High Sierra, available updates will show in the App Store. As they will, for that matter, for other versions of the macOS. I download these because I like to archive them for use on client's computers.

Of course, why MacUpdate hasn't updated their links, well that's anybody's guess. MacUpdate Desktop hasn't worked for some time now. I get a connection error when I look for updates. Maybe everybody is on vacation and their skeleton staff can't handle the workload.
