Slickedit just announced a native version of Slickedit for Mac.
Until this new version there 2 options to run slickedit on mac. One, they had an x−windows version. It was pretty clunky and not very mac like. The other was the solution I took. I like slickedit so much that I bought a copy of vmware Fusion for the sole purpose of running slickedit in Windows in the Unity mode of Fusion. I've been living with that solution for the 3.5 years I've had a mac notebook.
Finally there's a true Mac version of slickedit. Yay!
