Hope someone can help me with this. I downloaded blender (a free 3d software compatible with 10.8) I disabled gatekeepr switching to allow application downloaded from anywhere and still doesn't open the app, I tried the right-click open the control+open nothing. Same situation with a demo version for video plugin for final cut and motion and same result. I try to open same software with a mac mini (os 10.6.8) no problem at all. Please please can anyone help me with this? Thanks in advance!
