I have just updated my os to High Sierra after a format. Through the App Store app, a version update was required (namely macOS High Sierra 10.13 Supplemental Update) so I did it.

Then as it was installing I encountered the following error,

The path /System/Installation/Packages/OSInstall.mpkg appears to be missing or damaged

I tried to fix it using some details from here. However the find command couldn't locate the missing file. For the record I entered all the commands in the aforementioned post.

So I went trying some stuff (which I don't quite remember) and somehow I managed to boot my computer normally (boots in the update resulted in a continuous update loop that I managed to exit). And now I have the same update pending in my App Store and of course I want to execute it.

Now, I wouldn't want to fall back to the bad update situation so I was thinking maybe to download the update again.

How can I delete the files from the bad update?

Is this strategy going to make any difference?

  • Try reinstalling High Sierra. Boot into recovery mode (Command + R) and reinstall without deleting your drive. After that done, restart, boot again into recovery mode and repair your disk permissions.

Try downloading the update from Apple's website rather than through the App Store, and installing from that package.

  • Did the trick, and the update requirement in the App Store update tab has now vanished! Thanks!
