10.13.2 supplemental update failed

Finally got annoyed enough to contact Apple support. The problem is not with the update it is with the current OS.

The solution is to overlay your current OS with a full replacement. This will not impact any of your setting etc so not a big deal. Simply do a Command+ Option+ R on reboot and re-install latest OS. Fixed me right up. Thanks Apple.

Correct, I didn't loose anything. That said if you read up on an OS re-install there are three choices. You can not do an install of the version that came with your mac. That is the Command -R choice. Instead you have to do the Option-Command-R version to re-install the latest version. Evidently my mac came with Yosemite and that is not compatible with Sierra. Notes on that I found here: How to reinstall macOS - Apple Support. One issue I have had and still have is I keep loosing my blue tooth mouse on boot up. Apple knows they have a problem with that one and they do not have a fix. I tried 10.13.3 Beta 6 and it still is a problem.

I don't know if it will fix "everything" but you should update anyway since it addresses "some things". There shouldn't be a need to reinstall macOS, but that remains an option to consider.

Back up your Mac prior to making any changes to its file system. To learn how to use Time Machine please read How to use Time Machine to back up or restore your Mac - Apple Support.

Firstly do you have enough free disk space, you must try and keep at least 10-15GBs free space so the mac can function properly.

Run Disk Utility First Aid to check for any errors.

Go to Macintosh HD/Library/Updates and remove any .pkg files.

Go to System Preference>Users & Groups>Login Items and remove any apps that are set to start when the mac is booted up. Highlight them and then click on the minus button. You can always add them back later.

Restart the mac.

Try running the standalone download again.

Same problem here. Update is never applied correctly. MacBook Pro will reboot, then after login, message will advise that install did not complet and need a reboot.... it never end.

I tried this update from App Store and also from standalone file. Same result.

Macbook Pro Late-2011 17", Canada-French.

I tried to install this update on an older iMac (iMac13,2 / iMac 27" late 2012 / 3.40 GHz) running Mac OS 10.13.2 and it failed. It would reach the "installing update screen" but it would not progress beyond that point. As I was unable to cancel the installation, I had to re-install the operating system. This system uses a legacy Ivy Bridge CPU. Could the Intel microcode update be faulty and could it be the cause of this behavior?

Update: I reinstalled the latest version of the OS using Option-Command-R and was able to apply the supplemental security update to my iMac (27", late 2012, iMac13,2). It took quite a while for it to apply the update. The machine does seem noticeably slower after the update. For example, when browsing with Chrome using multiple tabs, activity in one tab noticeably impacts the speed of activity in another tab. Waking from sleep mode is also a bit wonky.

Try this instead, once downloaded double-click to install.

Download macOS High Sierra 10.13.2 Supplemental

Move the folder 091-58876 out of the Updates folder, leave the .plist files.

Restart and then try installing again.
