I use a MacBook Pro (early 2011 ID 8,1) running Mavericks. As a recording engineer I use it for location work to record multitrack audio into Logic Pro X. However, it has recently begun stalling out mid-recording with a "Disk too slow" error message, I want to hotrod it with a Mercury Pro SSD from OtherWorldComputing.com so that it is lean and mean and this disk error never reappears. My question is how to fresh install OS 10.9 on a virgin SSD. I have no DVDs to install from since Snow Leopard. Now that the OS is a download from the App store it implies you already are running an OS on the machine which would not be the case here. What's the elegant way to do this? All help gratefully received.
