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
Ok I managed to fix it.
I had the game installed on 10.9 and then upgraded to 10.10 DP. I was getting this error, and managed to launch the game by deleting the "Larian" folder in my Home directory, the game now starts fine.
Ok this didn't last long. After playing for a while, I closed the game then tried to start it again, and I'm getting the same error message. I tried removing the Larian directory again, but this time it didn't work.
Edit: I found a proper fix, tried it a few times and it always works. I have the "gfxCardStatus" installed. If I force the nVidia card before launching the game it works fine. If I leave the default setting for dynamic switching, it fails.
