I'm sure a lot of you know of Sandy McGuffog (sandymc on GetDPI), the author of CornerFix and PhotoRAW for iOS. Sandy has also blogged in detail about the problems in demosaicing the Fuji X Trans sensor.
Sandy has been teasing us on his ChromaSoft blog about a new software product he is busy writing for the Macintosh, so I was anxious to find out what it was all about, as he had indicated that it was capable of processing the Fuji X-Pro 1 raw files, and I was already impressed by PhotoRAW's processing of those raw files.
I PM'd Sandy and he kindly sent me a link to a beta version of his new app.
So far I am very impressed with the results. It doesn't suffer from water colour effect like LR 4 and it has good controls for artefact reduction, allowing the user to reach a good balance between resolution and lack of colour artefacts. It is still beta software with the usual cautions, but never-the-less it is most promising.
This is a file processed with the new App, chosen not for it's artistic qualities, but because it is one that does easily show up water colour effects on the distant foliage, or colour artefacts on edges on buildings.

Please contact sandymc by PM if you would like to try the beta. Note it is Macintosh OS X only (Intel Mac with OS X 10.7 and newer). It does process other camera raw files besides the X trans, but I have not tried any other types yet myself.
