It renders in the background, all the time/as it needs it. For general work, it *should* be ready for output as soon as you've made the last cut and dropped it on the timeline. No need to render, and I don't think apple-R exists anymore.
You need to check if your MBP (or it's graphics card) on the first link I posted in this thread. My MBP doesn't support it
Thanks for that.To be honest, I only use a fraction of the facilities available in FCP 7. When I render a movie of 2.5 hours it takes about 4 hours, so I just leave it running overnight, it's not really a problem. I'll leave it for the moment.
