Update weirdness..

[knowhowe]

Hi all,

Needing your help and wondering if your collective wisdom can assist me with this..

My MBP 15 inch 2011 has been a faultless performer- until the most recent update, to 10.13.4.

All installed as usual until I came to restart when the progress bar on the startup screen got to approx three quarters, froze and then, after a couple of minutes, the screen went black. Same after several restarts, including in 'safe' mode.

Started up from my backup external drive, ran Disc Utility, reported all well. Tried restarting. Same as before. Reinstalled from Time Machine and all was well until (foolishly?) this morning I attempted to install the recent 10.13.4 Supplemental Update and exactly the same thing happened. I had to lose a morning's work at a crucial time restoring for a second time :O

Any thoughts on what may be causing this, people? Not keen to install further updates until I get to the bottom of it..

Thanks in advance

It sounds like a failed update. It's possible that running the combo updater would fix your issue, but I think you will need to do a reinstall of High Sierra while booted from the Recovery Drive. While this should not delete any of your personal data, it's always advised that you backup first.

What is the Combo Update?

Combo Updates are traditionally bigger, and will reinstall just about any part of the OS as needed, and typically can be run to bring an old machine up-to-date without having to run 4,5,6 or more individual patches. Can clean up issues. Not as common a need as years ago, but still nice to have available.

If, for example you had a machine running 10.12.0, the 10.12.6 Combo update could be run INSTEAD of 10.12.1, then .2, then .3, and so on....plus supplemental security patches and other associated updates.

[doublepost=1525394070][/doublepost]Thanks for your response.
A failed update once- but twice?
I have the combo u/d as advised.
Still nervous about re-installing the recent security update though.. :/
