Mac autosave versions (clogging my disk)

Hi, I’m working on a 2 GB Rhino file on mac. I see that Rhino now has the autosave included which I think corresponds with OSX’s time machine versions.
In an earlier Rhino release date I was able to browse old versions of my model (and delete them). I don’t see that possibility anymore. Is it somehow possible?
The ongoing autosaves (and added versions when closing the model and pressing cmd+S) are clogging my HD with lots of gigabytes and I would love to delete the old versions of this model.
Thanks for your help!
