High Sierra update 10.13.3 won't install

Hi my Mac book pro is doing something similar. The update will download, the install starts and they just ends. The setting Mac screen starts and then the desktop load and says some update not installed. I am not running bitdefender. Any ideas?

Try installing from MacOS Recovery mode: press Option-Command-R upon startup. First run Disk Utility to make any necessary repairs to your startup disk; then run "Reinstall macOS" to reinstall 10.13. Then run software update to ensure you've updated to 10.3.3. Also, before doing so, try resetting the SMC and NVRAM. These support docs might help:

Thanks for getting me on track with your solution.

Setup: iMac iMac (Retina 5K, 27-inch, Late 2015) with SSD 500 GB on macOS 10.13.3.

Problem: I downloaded macOS High Sierra 10.13.3 Supplemental Update (19/02/2018) via the App Store.

(The macOS High Sierra 10.13.3 Supplemental Update fixes an issue where using certain character sequences could cause apps to crash)

But after the download, macOS would not restart. The screen goes black and freezes.

Only solution was to power off completely and reboot.

But macOS didn't complete the update.

Retried 20 times => not working.

Official Apple support says: try to update in Safe Mode => not working.

Solution that did work for me:

Step 1: Download macOS High Sierra 10.13.3 Supplemental Update (Download macOS High Sierra 10.13.3 Supplemental Update)

Step 2: Clone your boot volume and boot from the cloned drive

(I had luckily already a bootable backup on an external USB drive made with Carbon Copy Cloner ! :-)

Step 3: install the supplemental update on the ORIGINAL volume, you can select the target during the install process

Step 4: Boot from the original drive

Lesson learned: never 100% trust what official Apple support tells you, but search yourself the Apple Discussions forum for a solution. ;-)

Uninstall Bitdefender per the developers instructions. At best it is worthless and at worst it can damage Mac OS. Mac OS was designed to be extremely secure and does not require any AV, Cleaning or any other "maintenance" apps. If simply left alone and kept up-to-date Mac OS tends to run very well for most users for years.

That is the correct link, please uninstall per the directions and then restart the computer in Safe Mode and then restart normally and re-test.

I'm having the same issue on my MacBook Pro, but I don't have Bitdefender installed. I have a sneaking suspicion Parallels may be the culprit, but I'm curious if anyone else with Parallels can confirm?

my iMac is on 10.13.1 and I've attempted to install the 10.13.3 update twice unsuccessfully. No anti-virus software and no Parallels on my iMac. I'm downloading the combo installer linked above to try next.

I would agree Mac OS more secure than most other desktop OS's however this is dangerous advice macworld for example has the following list https://www.macworld.co.uk/feature/mac-software/mac-viruses-malware-security-366 8354/ or plug mac os malware inintoour favorite search engine

https://duckduckgo.com/?q=mac+os+malware&atb=v89-1_f&ia=web.

I am also having problems. Right now, I've tried installing from the App store (it restarts several times but with no success) and from the combo (same result). I don't have Bitdefender. Any other way?

For more info, I'm running 10.13.2.

Any luck with this? I am in the same boat, no matter what i do i cannot install the 10.3.3 update.

2012 mac mini.

Tried:

-updating from app store

-downloading update
-downloading combined update

-updating from command line

-cloning to another disk and trying all of the above

no bitdefender, or AV software, not running parallels.

No parallels, no anti virus, nothing running in background and I don't really have anything unusual on this machine. I've attempted the install 6 times and my system has auto-attempted 3 times and all have failed. It goes through the entire install process as if it is installing, reboots, and comes up with no errors BUT the update is not installed.

Thanks for the help.

It was strange - I just let it run and it finally calculated the time

needed to install was 29 minutes. I have no idea why, but it finally

did get back to rebooting. I've never installed an update that took 30 minutes

to complete.

Thank you for the suggestions, I made several attempts in safe mode with no success, reinstalling the software was the option that fixed my issue. I find it strange that it required reinstallation of the software, possibly 10.13.1 had some issue preventing future updates?
