whatever you do, do not buy a macbook for music production lol biggest noob mistake. You will only be paying for the Apple logo honestly. From my understanding you need a PC rather than a laptop, the things we do with music production are CPU heavy so I would recommend a PC instead but if you cant get that right now I would say get an Asus laptop or something reliable, with an i3 or i5 intel CPU. if you can afford an i7 go with that. Make sure the laptop has atleast 8 gbs of RAM and if possible a SSD (solid state drive- a hard drive that is faster than your average hard drive) You will most likely need an external Harddrive for storing samples and such, also probably a USB hub for plugging in all your stuff like midi keyboard and harddrive. If you have an audio interface make sure that is directly plugged into your laptop, not the usb hub.
