The 2014 MacBook Air is still a powerhouse computer for relatively light tasks, and for running industry standard cue software: QLab.  This computer comes with QLab UNLICENSED however if you require a license, you can purchase one directly or have Bailey Stone Media purchase it for you, at a discounted rate. We recommend getting a license for any show that you are working on, to future proof for later, however we understand it is not always feasable.
