Hi there, LOVED the davinci upgrades - was all working fine, then suddenly could NOT render out project. It keeps crashing. Same settings as before. I've read extensively the other posts and the "read before posting" instructions. I've set up a log for my activity. This DaVinci program was paid for as a package with my blackmagic camera - not the free version and being unable to deliver (now been at it for two days with client waiting) is terribly disappointing. I still love the colourgrade abilities - I just don't want or need to be a technical team analyzing what's gone wrong. I'm on a Mac NVIDIA GeForce GTX 780M 4 GB 16 GB 1600 MHz DDR3 3.5 GHz Intel Core i7 HIGH sierra any help appreciated. PS it rendered out once when I deleted the audio tracks. Thanks all! HP
