Should I do this, or should i keep my Mac? If i should keep my Mac, do you have any programs to recommend to me? I don't think I really need it, but it might get handy

I have a 2011 model MacBook Air with 4 GB RAM, SSD and a dual-core Intel i5 (1.7 GHz I think) - it runs Ableton Live and Mainstage just fine. I wouldn't be surprised if the specs on that MacBook of yours are pretty similar or even better.Thomzi wrote:The Macbook (Pro) is a late 2008 model, and was bought in the start of 2009. The RAM is upgraded to 8GB, and the HD is upgraded to a Seagate Momentus XT 500GB hybrid drive (it's a hybrid between SSD and HDD, faster than HDD, but slower than SSD).
If you own Mountain Lion (same goes for Lion), you can download the installer and either burn it to a DVD or put it on an USB stick (needs about 4.5 GB of free space).Thomzi wrote:I don't have the formatting disc, so I can't reinstall it either.
To start, the audio output on your MacBook should work just fine. You'll also need a MIDI interface or some kind of MIDI keyboard with a USB interface (such as the Stage 2 or Electro 4, for example). A cheapy MIDI-to-USB cable (would probably cost around 10-30 euro, depending on brand and quality) should work fine; try to get one that is 'class compliant' (= doesn't need drivers), but most are these days.Thomzi wrote:By the way - What kind of equipment would i need to use my mac with mainstage? I guess i would need some kind of sound card, but I am not experienced within this topic. (Would love to get it fairly detailed!)
