Contrastmaster & CS5 on Mac?

I recently purchased ContrastMaster and installed it. I currently have 2 versions of PhotoShop installed on my Mac (running OSX 10.6.4) - CS4 and CS5. Contrastmaster is accessible and runs fine in CS4, but it does not show up in the Filter menu of CS5. I checked, and there is a CM file in the CS5 plugins folder.

Is Contrastmaster NOT compatible with CS5 in 64-bit mode on the Mac? If so, that's not at all made clear in the compatibility notes! Any plans on when a 64-bit CS5-compatible version for the Mac will be available?

ContrastMaster for Mac is only available as a 32-bit version at the moment. Photoshop CS5 starts in 64-bit by default. So in order to make ContrastMaster appear in Photoshop CS5, you need to click on the Photoshop icon in the Photoshop folder, choose File > Get Info from the menu and activate the "Open in 32-bit mode" check box. After that the 32-bit version of Photoshop CS5 will be started and ContrastMaster will appear on the Filter menu.

We are working on a 64-bit Mac version. I cannot give you a date yet.
There is a note on the Mac Version page that explain that you have to use the 32-bit mode of CS5.

A 64-bit Mac version of ContrastMaster is available now for Photoshop CS5. It runs more than two times faster than the 32-bit version.
