Desk Top on Mac

I love my Ring Cameras but am totally disappointed that 1. I can not pay to keep my old videos longer than 60 days. For example, I had something happen recently and now months latter I need videos and if they are not stored that is an issue.
2. Liked working on Mac, because it is larger than a cell and can download right. to my computer, find and mark favorites and then search with a filter for just my saved favorites.
Please consider supporting the laptop no just cell phones. As I get older, everything is getting smaller. I need to be able to take snap shots from a video to for police records easier.
