Rhino 5 trial for Mac?

Hi, I’ve been trying to get a demo of Rhino for my Mac but am running into some issues. After downloading the trial for Rhino 6, I can’t open it because my version is 10.12 not 10.13. I can’t find a Rhino 5 demo anywhere. Is there no way for me to test it on my computer? Thanks in advance for any help.

Is your computer so old you can’t upgrade to High Sierra or Mojave?

I resolved the issue. I didn’t realize there was a way to upgrade other than doing software updates… guess I’m not the brightest bulb! Thanks :slight_smile:
