According to the system specs, my Mac shouldn't be able to run Premiere Pro because it only runs on 5400 rpm. But I've started to download the trial version and it's begun to install, so I'm just wondering if downloading the trial version might be harmful to my computer. I just figured something would pop up alerting me that my hard drive couldn't support Premiere Pro. Thoughts?
