Hi All - My 2009 Nehalem Quad Core 2.66 with 10 GB of RAM doesn't want to play nice with Yosemite, and I would like to be able to upgrade to newer versions of Logic (right now I'm at 10.0.3). I'm also using a UAD PCI card and a Firewire 400 Apogee Ensemble with a 400/800 adapter with an original Central Station and remote for monitoring. The rig is good, but it's getting a little tired. I mostly do music for television, in the box, and when I record audio it's one or two tracks at a time. I used to have a bigger rig, but it's gotten smaller over the years. I'm thinking of getting a new Mac and a UAD Apollo Twin Duo to replace the UAD card, Ensemble, and Central Station. I run a reasonable amount of plugs, including the complete Slate, complete McDsp, ProTools, Ozone, a large suite of East/West instruments, Omnisphere, Addictive Drums, some Kontakt instruments, Stylus, and a few others. I use some of my older 32 bit stuff with 32 Lives. Nothing really chokes the rig I have now except some of the East/West orchestral strings and brass when I really try to load up the articulations. My question is about which Mac to buy. I'm thinking I don't need a Pro for what I do, but I'm not sure I can get by with a maxed out Mini, either. I could get a Dual 3.0 Mini with 2TB Fusion Drive and 16 GB of RAM for $1500. Or, I could get a Quad 3.4 iMac with 3TB SATA Drive and 32 GB for $2950. That's double the bread, so I'm wondering whether it is going to be worth it for my purposes. Anyone have an expert opinion?
