I am getting ready to upgrade to a new Mac. I'm looking at a Mac Mini with a 2.3 I7 processor, 16 GB or RAM and 2 internal SS Drives. My only concern is that 16 GB is the max for this machine. I'm running Logic Pro X and this system will be dedicate to that and basic email and web browsing. My projects are mostly midi drums and audio tracks. I run very few software instruments. Any thoughts on when the 16 GB or RAM might become a bottleneck? I'm getting pretty old and I would like this machine to fill my needs for many years.
