I'm working on Imac OS X 10.5.8
It's PS CS5.1 v12.1 x64
I ran the installer and get an error message that PS does not recognize this type of file
I know about the compatiblity but came across this little nugget...
Imagenomic plans free plug-in updates for CS5
Imagenomic will be providing FREE compatibility updates of its Plug-in Products (Portraiture, Noiseware and RealGrain) for Adobe Photoshop CS5. Furthermore, we will be providing a FREE update for registered users of the Portraiture Plug-in for Lightroom to ensure compatibility with Adobe Photoshop Lightroom 3… For Mac OS X: We will be releasing compatibility updates to make sure our Plug-in products are fully compatible with Photoshop CS5 in both 64 and 32 bit mode.
now just need to know how to make it happen...
Just as an aside, I'm running Imagenomic's Portraiture plug-in on a Win7 Pro 64Bit machine with Photoshop CS5 and it runs flawlessly.
I was recommended the product by one of my clients, I work in IT Sales, who runs a portrait business; they're running the software on iMacs with Mountain Lion, AFAIA, and Photoshop CS5, without a hitch... I'll ask if they're also using the Noiseware.
