Hello everyone, I am new here this is my first post but I do plan to stay active as I enjoy apple products. My question is simple. I installed the Mac Lion Developer Preview 4 on my external hard drive on my iMac (16GB Ram, 27" 3.01 GHz if you need to know). I want to have my regular snow leopard back. What do I do. It does not recognize my external hard drive as a hard drive. I can not eject it. Just open it? I like the new OS, yet want to move back to my stabler one. I still should have Snow Leopard installed on my internal HDD right? I only installed it to my external hard drive? If I want my old OS still on my Macintosh HD (hopefully) what do I do?
