Updating to macOS Sierra from OS X 10.6.8 My OS is 10.6.8.  Yosemite is no longer available in US.  But Sierra needs 10.7 to download. Help! I'm stuck in a loop!

And cannot install my new printer until this is resolved. :/
You can install El Capitan from the App Store (even on 10.6.8) for free, and then update to Sierra after completion.
