Sure, I’ll throw in my 2 cents. I needed a laptop for when I travel to other locations, and settled on the new 15" Retina MacBook Pro (loaded). Just for the hell of it, I tried it as a master running VEPro, using my PC as a slave to host most of the VI’s. I was brand new to Mac, but it was very easy to learn OS Mavericks. To tell you the truth, I prefer using the Mac and have decided to make it my permanent host for Cubase 7. IMO, there is no difference in performance based on my own experience. The video handling is especially good, as the top end model has a 2GB video card as well. I don’t bother with all the benchmarking, etc, because if something the works the way I need it to, that’s what’s most important. Since switching in November, I have successfully completed several projects this way and the Mac has already paid for itself twice over. I have two additional monitors connected, gigabit Ethernet (via Thunderbolt), an external drive, UR 22 interface, and a 7 port USB interface http://www.ianker.com/product/68ANHUB-SA7A
I’m looking at getting one of these. A colleague bought one recently and it works great http://www.caldigit.com/thunderboltstation/
I have also tried heavier projects using JUST the MacBook, and as long as you keep everything under the 16GB Ram limit, you’ll be fine.
The whole Mac/PC thing is a hot topic as you know (and a waste of time). If anyone is thinking about blasting me for being a “fanboy” or whatever, save your energy. The OP has asked a legitimate question. I am not bashing Windows…I still work on PC for sound editing, etc, and Win 7 is an excellent OS. It just happens I prefer working on the Mac.
Ok, there’s my 2 cents!
