I think I'd like to try the upgrade from El Capitan to Sierra. I can't go all the way to High Sierra without Sierra first, correct?
I want to install on one hard drive and be able to pull the drive out if I want to keep El Capitan.
Cheryl - you gave me a download link before to get a clean ISO install of El Capitan. Is there one also for Sierra that I don't have to go through App store?
I may not even want to keep it, just want to see if it's all compatible with Adobe Creative Suite/Cloud.
Thanks, all -
