VMWare Fusion

That was well nigh impossible. GUI fail, on gparted's part.

These steps won't be 100% complete because it's 7:15am and i spent the last hour frying my brain on this stuff (after the brain unilaterally called a break about 2:15am and i fell asleep), but they do fill in some gaps other resources out there don't quite cover. Some even seem to (falsely) suggest that unallocated space must be made into its own partition first. Here are some of the better links; my (final working) steps below.

In order for the cool myprojectname.dev style addresses for sites you are developing locally (rather than 127.0.0.1/myprojectname) from my Mac OS X environment as well as Ubuntu running in a virtual machine, this method uses the IP address available locally that you can find out by typing ifconfig in a shell terminal. It's what follows the text "inet". With luck that is a stable IP address, running in bridged mode (i think) with VMWare Fusion this seems to be working so far. The problem with bridged mode is that it only works with your own internet connection.
