Cannot install OS Mac High Sierra

I downloaded High Sierra from the Mac store and received the following error message during the installation process:

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

I don't know how to quit the installer since I am stuck on this screen. I have rebooted several times, only to come back to this screen/error display. I tried a Safe Mode restart but have been stuck in it for over an hour.

Any help would be appreciated. Thanks.

macOS Sierra (10.12.6)

The reason the problem continues even after closing the installer is that the installer file is corrupt and the system is using it as the boot disk. The problem will continue until you set your computers System Disk as the boot disk. Here are the steps I used to set the boot disk.

Click the dialog box, not Restart. This causes a menu bar to appear.

Click Utilities and choose the Startup Disk option.

Choose your System Disk as the Startup disk.

Click Restart.

Once the system restarted, I downloaded and successfully ran the update.

I wish I had come across this thread earlier, because I just wasted a ton of time.

So my fix worked, but it was painful. AND, you better have a recent time machine backup, if you want to try it.

So you boot with the option key to the recovery disk. Next choose the option to format the SSD and install the most recent compatible version of OS X. Now I know that sounds stupid, because I was at 13.3.2,going to 13.3.3, but once it failed over and over, I got frustrated and took the nuclear option.

26 hours to restore from backup on the time capsule to get back to where I was when the App store told me to automatically update to OS X 13.3.3.

So, now, here’s my question. Am I stupid enough to try to go to the latest version again.

One final note, I’m running a mid-2011 Mac Pro laptop with 1TB SSD and 32GB of memory. It’s getting a little long in tooth, and I’m wondering how many more versions I’ve got left before Apple obsoletes me.

Thoughts?

I tried to install macOS high sierra on my MacBook Air, but after the reboot I find this blinking image (a question mark in a file log).

Could you help me?

Ended up buying another external hard drive , backed everything up and booted to recovery and reinstalled OS. Took about an hour and a half to install but everything is working fine.

Plug in your external hard drive, boot into recovery mode then create a new disk image

As long as the external drive has enough space to cover whatever you’ve got on your Mac hard drive, you’ll be fine.
