I am using OS X 10.9.1 on a 15inch macbook pro which is a 2009 product.
I need to zoom into various parts on the screen and capture the screen activity. I am using quicktime screen recording for capturing the mouse activity and it is doing a perfectly fine job. However, when i zoom into the screen using 'cntrl + mouse scroll up' the text pixelates. I need crisp text, not blurry. How can I achieve this ? If I use a macbook with retina display screen will it give me better results ?
