I'm a Machead running a 15" MacBook Pro with a six core i7 processor and 16 GB Ram with a 256 GB SSD. I use a Glyph Atom SSD for the Logic sound library and a Samsung 2TB external drive to record/playback to. This system has never hiccuped, gagged or crashed on me. I just bought a Quantum 26x26 and now I have 2 millisecond round trip latency as well. I know Macs are scorned by many because of the price compared to Win, but I can testify that this system kills it for me. Good luck with whatever road you walk, Francis. - Michael
