I have problem installing macOS High Sierra from App Store. I don't understand what the problem is, but when the download completes it suddenly resets. Then when I open up App Store again it only lets download the os again.
I want to clean reinstall High Sierra on my Mac and the only way to do it is to create bootable flash drive because I have a bad internet connection.
I have downloaded macOS High Sierra combo update with a download manager, and my question is can I create bootable flash drive with this combo update?
