QuickHash v2.8.4 for Apple Mac OSX is now available from the downloads section. It should hopefully just run when the app is extracted from the zip file, but you may need to adjust the security settings of your OSX system to allow it to run, as it is not signed.

In the future, I may provide signed versions of the program depending on the results of the current poll which is to establish how many people would like a signed version of the program.
