If I downgrade my back up mac (late 2009) back to Snow Leopard will it hinder my usage of CC17?
I have CC17 running on Sierra i7 quad core and it's great.
Yet, I also currently have CC17 running on Yosemite late 2009 dual core and it's okay, but I much rather prefer this machine
to run on Snow Leopard.
CC 2017 products will not run on Snow Leopard (OS X 10.6).
e.g. Photoshop CC 2017 requires min OS X 10.10 (Yosemite).
