I've spent over two hours googling and searching and just can't figure this out. Any advice deeply appreciated.

- Spouse and I have set up a steam family and the games are showing up correctly in each other's libraries.
- We have a new Mac mini M4, and have separate profiles we log into, and have each been playing our own games on steam on our own profiles
- We want to play some of each other's games, which we now see in family sharing, but get prompted to install it again on the same computer, which seems like a waste of drive space

Here's what I've tried:
- Using mac's File Sharing to make the steam app install folders for each user public to the other (couldn't get steam to open/recognize the path for each user)
- Tried going through Steam settings > Storage > adding/changing drive location (doesn't seem to work unless I literally have a separate external drive)
- Tried setting up a new default install location in a shared folder, with the thought that I can move all the games there (couldn't get it working, and all the directions are for the windows version)

This feels absurd. We have 2 user profiles on the same computer and the games are shared. How can we access them without taking up double the hard drive space? Thank you in advance for ANY advice.
