and I was able to reboot my iMac mid 2010 (with very long USB loading times). So I installed High Sierra 10.13.6 on an external hard drive (USB) to test my guess (HDD corrupt).
This is probably due to a problem on the internal hard drive, the original 1TB HDD. At each attempt, this message appeared: cannot complete the installation due to a problem. Unfortunately, none of the various attempts were successful.

Then I created an installer via usb stick, and tried to install the operating system on my iMac Mid 2010 (iMac11,3). I was able to download the macOS High Sierra 10.13.6 full installer version thanks to a mid 2012 macbook pro with macOS El Capitan installed.Īll other attempts with the latest mac book pro and already installed versions of the operating system (Catalina or Mojave) have been unsuccessful. If you already have Mojave installed in your mac and what to update to the latest version download 'Update for Mojave 10.14 or later'. Restart your mac and try downloading High Sierra again. I am not entirely sure it will make a difference but uncheck that box. "Downloading new updates." is a bit misleading it is in fact downloading Install macOS High Sierra.appįrom your earlier screenshot of the Software Update panel you have checked the box Automatically keep my mac up to date. When I click on Download the Software Updates window opensĪnd after a couple of minutes I see this, This will redirect you to the App Store High Sierra page Go to Section 4 and click on Get macOS High Sierra

How to upgrade to macOS High Sierra - Apple Support (My mac is/ was capable of running High Sierra) I am doing this on a mac with macOS Mojave 10.14.6 installed. If that is not the case then I probably do the same a you. Apple does not take into consideration that you want to download the installer and then install it on another older compatible mac. The reason I ask is that any mac that came preinstalled with a newer OS than High Sierra will not be allowed to download High Sierra or any older OS. Mike you are trying to download High Sierra to your MacBook Pro, did this MacBook Pro come preinstalled with Mojave or Catalina. Yosemite UX Pack will give you all new OS X Yosemite user experiences combined with iOS 8 graphics such as theme, wallpapers, and new OS X features combined altogether in single package working on Windows 7/8/8.1/10 without touching system files at all so it won’t have such risk to harm your system at all.
