thanks for the reply, I have 349 gb left on my mac mini, most files are projects from logic pro 9, and how do i go about upgrading my mac mini to 8gb of ram ? and its a 2.5GHz dual-core Intel Core i5 (Turbo Boost up to 3.1GHz) with 3MB L3 cache. and im using everything stock from the logic pro library and stock plugins. nothing fancy.
