What video card do you have in your Mac?
Hi Jack. It is the NVIDIA GeForce GT 120.
I'd send Dannylo an email and ask him, he's very responsive to users. I suspect it's an issue with how his software is utilizing the video, but he'll know for sure and may already be aware of it. I have not noticed any issues with my P65+ files, but I have not used HF enough since I got the P65+ to make a blanket statement. I'm also running a GTX 285 which has 1G of VRAM.
