Jun 22, 2018  The update gets stuck with a message “mac os could not be installed on your computer an error occurred installing macOS.” Some folks report seeing this message as well “the path /System/Installation/Packages/OSInstall.mpkg appears to be missing or damaged.” Then your Mac prompts you to quit the installer and restart your computer.

3. My Mac Won't Update Software

I'm trying to update my 2011 MacBook pro from OS X 10.7.5 to the latest version Sierra.

Basically the install won't finish and gets stuck on a page with an apple logo and loading bar (see photo). I've tried all of the recovery mode stuff and restarting the Sierra install. For some reason I can't just go back and reinstall 10.7.5 because Sierra is now installed on to my Hard Drive?

I also had about 30gb of free disk space.

This is really annoying me as I am a music producer and heavily rely on my laptop.

I'm also worried about my data being lost?

Can anyone please help?
