install mac os high sierra macbook air 2015

a bummer.Anyway, I was having a problem because the High Sierra did appear in my updates tab in App Store and I could click 'UPDATE' but it would immediately show me an unclickable 'Installed' button after clicking it and in 3 seconds turn back to a clickable 'UPDATE'.When checking About this mac I would see that the macOS isn't Hight Sierra although App Store shows update was installed.😕Here are some screenshots for clarification: (This is what I could see even after clicking UPDATE/UPDATE ALL)But if you scroll down you see: (an installed update for every time I clicked any of the UPDATE buttons)So long story short I gave up and manually downloaded High Sierra (22 mb version) from App Store by searching for it, and installing it. App Store not functioning after High Sierra Hello,Before upgrade: OS X Yosemite (10.10.5), 21.5 inch Mid 2010.Some background: I was trying to download the full High Sierra (4GB) in order to make a bootable drive for a clean install.That didn't work out as I was only able to download the 22 mb version of the installer.
