What "project file" stores the currently open scene (MAC)?

When you open a scene, save the project, close Unity, and reopen Unity and the project, the scene that was open in the last "session" is now open in the new session. In what file is that information (currently open scene) saved?
Thank you.

 

Not sure, but you can use your version control system to figure it out. For example, I use trusty SVN so I'd just open a project, open a different scene, click save project, then run command "svn status". Whatever file that has been modified is the one you're looking for.

 

Hi. Thank you for the suggestion but that's sort of how/why the question came up. Whatever file it is that's changing isn't being tracked by GIT. Probably something in the ignore file that shouldn't be there.

 

It's because the last opened scene isn't tracked by the project itself but by the editor and stored in its own settings file which for macOS is ~/Library/Preferences/com.unity3d.UnityEditor5.x.plist. It's done this way because multiple people working on the same project won't be working on the same scene at the same time.

That's what I was looking for. Makes sense. Thank you.
