You can install now SPE in your Macintosh in a way you do with native applcation.
Simply mount the DMG and drag the SPE to Applications folder.
Another advantage is, that now SPE will have its own icon in dock, like any application in Mac.
I will release soon SPE 0.8.4.e with some important bug fixes and I hope Krzysztof Olczyk will update the package for the Mac.
Please test the package and let Krystof know how it works.
