<p>Jack, I tried getting Canon's ImageBrowser but it doesn't run on anything after OSX 10.8. I have 10.10.<br>
Jeff, that works. It would be ideal to be able to see a list of the files with the times of each shot one after another, but at least I'm able to confirm my suspicion about how often the shutter is really activated with my time lapse gear. <br>
When I get it, I'll try both PS & LR.<br>
Thanks for the answers.</p>
