Since Mercurial stores everything in a .hg folder at the root of a  
checkout, I'm pretty sure Time Machine won't adversely affect it.

However, Time Machine ain't version control. It's a backup method.  
Version control does provide a backup, but that's almost beside the  
point. "Change management" is a better way to think of version control  
in this context. Time Machine is merely a stenographer, in comparison.
