Crashes - is this typical or just because I'm using the unstable 1.1?

Being new to FreeCAD, I was just wondering if the crashes I'm experiencing on v1.1 are typical or just because it's not "stable" as 1.0?

If it matters, I'm on a Mac system.

And I think I already know the answer to this, but is there a setting to "autosave" so I won't lose my work? I'm guessing not, but I figure it doesn't hurt to ask. :)

Thank you - have a wonderful day!
