Question:

Question: Upgrade OSX from Yosemite to High Sierra

Mac type: MacBook Pro

Speed/Memory: don't know and can't currently get access to this info

Storage Capacity: 500GB

Version Number: OSx Yosemite - but can no longer get access to info regarding which version


Problem:

Tried to install High Sierra. It seemed to install but when it came to restarting the following message came up:

"The path/system/Installation/Packages/OSinstalll.mpkg appears to be missing or damaged. Quit the installer to restart your computer and try again"

Trouble shooting steps:

  1. I have quit the installer and re-started but exactly the same thing happens.
  2. I have tried starting in safe mode but it made no difference.

MacBook Pro, OS X Yosemite (10.10.3), approx version number of Yosemite
