Hello everybody, Around 4 months ago I bought a 2.4 ghz alu-Macbook, and I've generally been very impressed with it. However, since my Dell crapped out on me, the burden has fallen on the Macbook to handle my music recording and editing demands. (Bear in mind that the Macbook was never intended as a straight ahead desktop replacement.) Anyway, I've already asked for advice using a different thread (http://forums.macrumors.com/showthread.php?t=648815), and I think the conclusion is that the Macbook is perhaps powerful enough CPU-wise. However, the main issue is the lack of firewire for recording direct to an external hard-drive. Assuming that USB 2.0 isn't fast enough or stable enough, the only option available is to record directly onto the internal system drive. I know that this isn't the perfect solution by any means, but can anyone explain the dangers or consequences of doing this? If needs be, I've already budgeted for a new desktop- maybe a low end Mac-Pro refurb- but I want to test my Macbook's capabilities first as I'd rather not waste the money. On the flip-side however I defintely don't want to overburden my Macbook if it isn't capable. I'd appreciate your advice greatly, Ben. P.S. My demands aren't too great. I'm not an electronic musician. I just want to make professional sounding backing tracks with acoustic/electric guitar and at most a two or three midi loops (bass loops, drum beats etc.) As a serious acoustic guitar player audio reproduction quality needs to be good however.
