Hi, I used the 0.5.0 installer on OS X Lion (10.7.2) today and the kext did not load. I used kextutil to diagnose and received this message:

/System/Library/Extensions $ sudo kextutil osx-pl2303.kext
Diagnostics for /System/Library/Extensions/osx-pl2303.kext:

Changing permissions resolved the problem, and the driver now loads!

/System/Library/Extensions $ sudo sudo chmod -R g-w osx-pl2303.kext
