I'm updating OS X EL Capitan to High Sierra.

Today morning I was go on App store and download High Sierra. After downloaded the installer opens automatically and I clicked on "Continue". From apple's official document.

But last 3-4 hours my installation process is stuck mean not progressing further.

enter image description here

So what can I Do? Why this is taking to much time? Should I cancel and restart the system and again try to install it? Or keep patience?

If I cancel and restart system and try again then I will be make any major problem? I don't know what I should do. Please guid me on right direction.

    The need to press Cancel or hard reboot should be inversely proportional to the time since your last full backup.

  • If I will stop and reinstall again then any problem will occur or not?

  • You won't know until you try it, which is why you need to weigh the temptation against how recent your backup is.

From my own experience:

Why this happening? Why my installation is not progressing further? Because issue is in my network. I connected my system with WiFi and sometimes signal comes with very low quality and in between installation for some second signal was lost and at that time installation is stopped/pushed. That was reason of installation is not progressing further. But I tapped on cancel but even don't know what will happen! and restart my system and clicked again for installation. It will not be started from begging but started from where we stopped/pushed. Its really good things. And I was write comment like

if we canceled installation and restart again then any major problem will occur?

Answer is No you can do cancel and reinstall process any time It will be managed by core system.
