Computrainer and Mac book pro 15inch retina

I can get Zwift up and working with computrainer and is stable as long as I don’t peddle but when I start peddling after around 8-10 secs it will crash , have done a reinstall of Zwift but still no joy , Mac is running OSX 10.10.2 with 16GB memory and 2.3 Intel core MHz and Intel iris pro 1536 MB graphics , any ideas please ?
Thank you
