Problem Installing High Sierra

Trying to install High Sierra on my mid-2010 iMac currently running 10.12.1 and having problems getting the whole thing to complete. After the agreement acknowledgement, I click continue and will get a message saying "In order to continue installing macOS High Seierra, you need to log in as administrator. Install macOS High Sierra is trying to add a new helper tool." I click on "Add helper", it gets down to as little as 4 minutes remaining and then it just stops. I've tried quitting and restarting it at least six time and will get down to varying amounts of time remaining and stops each time.

What can I do get this this install to complete. The last attempt got down to 27 minutes before stopping.

Thanks!

This is a long shot, but,

In reply to: Problem Installing High Sierra

High Sierra is a version of the Mac OS that is installed by downloading from the App Store.

That said, unless you have a good, uninterrupted, internet connection with the App Store the install is likely to fail.
The complete download of High Sierra is in excess of 5GB, with the internet connection remaining stable throughout.

A possible solution is to download the entire thing without installing it, just saving to the hard drive ready for use.
For complete instructions on how to do this go here:

and read it carefully, a couple of times.

Let us know how you get on

My latest attempts

In reply to: This is a long shot, but,

I've decided to not install High Sierra but, rather simply try going from 10.12.1 that is currently on my system to 10.12.6. and am still having major problems. My latest attempt have been to try an internet recovery as well as a regular recover. Each time they end up just "hanging" there doing nothing. I just attempted to do an internet recovery again and got slightly different results. Shortly after starting holding down the Option-Command-R keys, it brought me to a drop down menu to select the wi-fi connection. It had my wi-fi name already selected with no other button to push to continue. I let it sit and about 5 minutes later a gray globe appeared with an "!" in the middle and "-2002F" below it. It did not do anything else after that. Can anyone tell me what this means? I assume it's an error code.

I've been racking my brains out trying every suggestion offered and finally found the solution. Someone posted a link to the Apple community regarding an error code of -2002F I was getting. It was saying that sometimes the Wi-Fi connection can be a problem when trying to install software and to shut off the Wi-Fi and plug directly into the router. Hooked the computer up directly to my router, hit Optic-Command-R and it installed on the first attempt. If you have gone through what I have gone through, then you can appreciate the feeling of frustration and final success.

Wow, it feels so good to finally see success.

Good to see that you are back in business,

In reply to: Finally - Success, Success, Success

but the suggestion that your internet connection was the weak link was the first suggestion made.

Anyway, full marks for perseverance
