Question: Upgrade to High-Sierra failed

I am running iMac with Sierra installed. To upgrade to High-Sierra I used Net-Update (recommended in a email from Apple). After downloading the complete Sierra, an error occured and there was no way to boot anymore.


Now, using the Option Key I get the chance to select the 'OS X Base System' which tells me that:


"mac OS could not be installed on your computer, the path /System/Installation/Packages/OSinstall.mpkg appears to be missing or damaged"


--> this "OS X Base System (image) of High Sierra cannot get unmounted.


** I tried to get a bootable OS X stick from Apple, to solve the problem. Unfortunately they dont have this.


** I have a complete Backup, however, without a running OS X its of no use.


Hope for help. Thank you very much.

Answer:

No, I have no access to another mac. that was the reason I tried to get a bootable stick via Apple-Support. But, no way. Bring-in the 24" iMac, just to get the stick there mounted, was not a good solution to me.


I installed Linux (parallel) and with a couple of tools I could repair the damaged partition.

A tiny version of macs disk-utility helped installing mac-os x from time-machine.


Now, everything is up and running including a bootable-installation-usb-stick.


Thank you very much for your help

Do you have access to another computer where you can download High Sierra from the App Store using your Apple ID? Quit the installer and make a bootable USB Drive to boot the computer. You can make a bootable USB stick to install using this free program which will do all the work for you. If you have a backup of your computer, consider using Disk Utility to erase/reformat the drive before installing.

I have a feeling the e-mail was a scam. Do not download High Sierra from anywhere other than the App Store. Do you having a working computer now? If so, try installing High Sierra by downloading it from the App Store. Do a backup, preferable 2 separate ones on 2 drives before trying the installation.


If your computer isn't working, boot to the Recovery Volume (command - R on a restart) and select Recovery Volume. Run Disk Utility and select First Aid. Then re-install the OS.

Thank you for the quick reply.


I did repeat the download from macOS Recovery (Internet Option). Download perfect, then blank screen.

I cant download from App-Store because this needs a running OS


All I can do (with mac) is going to macOS Recovery and limited functions there (no macOS Utilities eg !).


--> what I would need is kind of basic installer or 'macOS Utilities' but not .dmpg 🙂

Correct, I couldn t install it anywhere. After downloading the system, the system went blank with Apple-logo and nothing happened (for hours). Somehow it looks for an installer app.
