I have a MacBook Air (I also own an iMac but the MacBook Air is more portable) and I have a small 3000 Lumen Projector to play with and learn how to use VPT7. My OS X is version 10.9.3. The instructions manual is great, the YouTube instructions and examples are great but I just need to figure out how to get VPT 7 recognized as an application I can open on my computer. When clicking around looking for the downloads page, I receiving an message saying that the software is not recognized as an Apple approved product. I am very excited to try this product out. I work in a High School Theater part time and I would like to get experienced enough with VPT 7 to use it for video mapping, FXs for band concerts and small student plays to jazz up the background. The High School has a 10,000 lumen projector. Can you help?
