We are currently working on a new installer for OSX that will be released with LimeWire 1.4c or LimeWire 1.5. The new installer is much easier to use, and is similar to other traditional Mac installers.

I posted on other threads that the new version would be released last week, but we have delayed it for several reasons (including putting the finishing touches on the OSX installer). It should be out sometime in the next several weeks, however (I want to avoid sticking to an exact date in case anything comes up).

The new version of LimeWire for OSX will also be a much smaller download, probably under 1 MB.
