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


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
