Newbie here. I have two 27-inch iMacs side by side on my desk, a 2012 and 2017. The newer, faster model is for video editing and music production; the older one is now relegated to the business/office/writing machine. (I create content for the music products industry for a living.) Is there a best practice for which machine I should install Across on and use as the Across server? For example, if I use the slower iMac (which is where I normally keep everything but media creation apps), would anything about the communications affect the performance of the faster iMac? Thanks.
