My favourite little thing about OS X Mavericks is the fact that the sleepimage file in
private/var/vm
is no longer the size of your complete physical RAM anymore! It’s much smaller, like only the active part or a compressed version or something. My sleepimage used to be 8 GB, now it’s only 1.1 GB! For someone like me who is always running low on hard drive space, this is a big relief!
