Make sure you back it up.

Check your applications to make sure they will be compatible with High Sierra. http://roaringapps.com is a good resource.


Once you have confirmed you have a good backup, open the Mac App Store. Find High Sierra in the store, and click the button to download and install it.

I tried to install after backing up. Message from High Sierra "can not be installed on this computer"

Then either your computer is too old to support High Sierra, or it does not meet the minimum requirements (free disk space most likely).
