I have a mid-2010 i7 27" iMac with a fresh install of Yosemite. Just picked it up used. The hard drive seems to be really slow in this machine, and it only has 4 GB of RAM.

The problem I'm seeing is that when open up iMovie and throw some clips together, at some point, I can no longer preview the video by pressing the space bar. I can export the video just fine, but when I try to play it in VLC, it doesn't play.

A restart allows me to play just fine. Has anyone encountered this kind of issue?
