Apple Security Update

OS and security updates now predominantly bring limitations and more and more nontransparent control and processes. Mojave 10.14.6 is maybe my last update on my 2018 MBP. I don't trust Apple no more. After more than 20 years working with Apple computers I feel that they deviated and we no longer can be safe like we were. Still infinitely better option than Windows or anything else but I feel something sinister. :(

Security Update 2020-001 was released on 28 Jan 20. More info: https://support.apple.com/en-us/HT210919

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.

Works fine as usual

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??

This is great, thanks! Does anyone know where the 2019-001 update from Jan 22 is?

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.

Yes, Apple Security Update Version 2018-004 is from a month ago, July 9, 2018. You are not hallucinating. You most likely already have it installed.

When applying SecUpdate2018-004 to previous SecUpdate2018-003 installation on El Capitan, HEADS UP. There were TWO SecUpdate2018-003 updates for El Cap, an initial and a slip stream version that Apple very quietly slipped in to replace the initial one a few days later. If you installed the initial SecUpdate2018-003 download, the build number shows 15G21012, if you waited and downloaded it after Apple replaced it with the new one, the build is 15G21013 when completed..

NOW, if you try manually try to run SecUpdate2018-004 over SecUpdate2018-003 build 15G21012, it will refuse and say the SecUpdate2018-004 update can not be installed. Run it over SecUpdate2018-003 build 15G21013 and no issues. I had to first RE-APPLY SecUpdate2018-003 (the newer one and the one you get currently if you download a fresh copy from Apple) to get the build number from 15G21012 to 15G21013. Then I was able to apply SecUpdate2018-004 (which results in build number 15G22010 btw).

I don't know if it would have worked had I gone through MAS ; I always apply my updates by manually running the installer BECAUSE I always boot from another drive to run update. That's a tip everyone should follow, i.e. never boot from and install an update to/from the same boot partition. In my experience, this virtually eliminates the reports you hear about the update taking forever, and or the system taking forever to reboot, or runs slow after the update. This is because by booting from a different drive, the one you are updating is completely accessible and files can be updated quickly without delay. If you try to update the same drive you boot from, not all files can be updated first time around because the system is still running, its like trying to replace a rug while you are still walking on it. it takes a few reboots and a lot more time before everything is updated. With disk drives so inexpensive and HUGE these days, there is no excuse not to have an external boot drive or to divide your existing internal drive into multiple partitions, plus macOS is SO easy to clone and excellent cloning software is readily available (Chronosync, SuperDuper, CarbonCopyCloner to name just a few). In any case, for emergencies, you should ALWAYS have another boot option available to regain access to your working partition in case of trouble.
Peace.

SecUpdate2018-004 has been out since July 9, but the MacUpdate crew hasn't gotten around to adding it yet, so I thought it would be worth posting links to SecUpd2018-004ElCapitan: https://support.apple.com/kb/DL1972 and SecUpd2018-004Sierra: https://support.apple.com/kb/DL1971

Weirdest security update ever (2018-003): the installation (onto an HDD) was very fast, faster than usual, but login into my main account—and I'm not kidding—took 6 (six!) hours for even my Desktop to show up, two more hours for all the startup items and scripts to load/run, and the machine was sluggish for many more hours. Now it's all good again, snappy & stable. But if you get the spinning beach ball for seemingly forever, don't force-shutdown, just wait it out, go to work, go party, read a book.

As of June 4, 2018, this MU listing is incorrect. It is actually Security Update 2018-003 for Sierra and El Capitan is the most current. For High Sierra, the fixes are included in 10.13.5 update.

2018-03 for Sierra here:
https://support.apple.com/kb/DL1968?viewlocale=en_US&locale=en_US

2018-03 for El Cap here:
https://support.apple.com/kb/DL1967?viewlocale=en_US&locale=en_US

10.13.5 combo for High Sierra here:
https://support.apple.com/kb/DL1965?viewlocale=en_US&locale=en_US

I ALWAYS recommend using the combo updater, even if updating from the immediate prior release, for example, even if updating from 10.13.4 to 10.13.5, I would still using the combo, not the incremental. I've experienced several instances were the incremental is missing necessary files or misses files from previous updates that for whatever reason didn't get updated. The combo by design will check all files back to the 10.x.0 release to confirm all needed files are current. And I always recommend booting from another partition or drive to run updates, i.e. don't boot from the same partition drive you also plan to update; this ensures the partition to be updated is offline and files are all accessible; dramatically reduces the time to run the update, in my experience.

Be patient with this one. My early-2011 MBP made a buzzing noise (firmware update?) and rebooted twice. After the second reboot, it seemingly sat dormant with the Apple/gray screen for some time before finally bringing up the login screen. Grab a snack and let the update do its thing, all will be well.

This does not point to the 2017-001 High Sierra update - which right now is only available via the App Store. This is pointing to the supplemental update released several weeks ago..
