Mac ap we nɔ gɛt ɔfishal wan

The unofficial Mac app watches directories of .less files and compiles the code to local files after every save of a watched .less file.

If you like, you can toggle preferences in the app for automatic minifying and which directory the compiled files end up in.

More Mac apps

Crunch

Crunch is a great looking LESS editor and compiler built on Adobe Air.

CodeKit

Created by the same guy as the unofficial Mac app, CodeKit is a Mac app that compiles LESS, SASS, Stylus, and CoffeeScript.

Simpless

Mac, Linux, and PC app for drag and drop compiling of LESS files. Plus, the source code is on GitHub.
