Mac Yosemite 10.10 DP2 on a rMBP Late 2013 2.3GHz, 16GB RAM, Intel Iris Pro + nVidia GT750M 2GB
- Both 10.10 DP1 and 10.10 DP2 fail to launch. I get the splash window with the version number (1.0.115), it turns to a black screen, then switches back to the desktop with a "Video System Failure" message
