I just did my first RawTherapee build for MacOS. The build should work on systems with Mountain Lion (10.8) or higher. Please note that I have not built on a generic processor and so on non Macs, it may not work.
To test, simply download the zipfile and unzip it using Finder. Then double click on the app. You can also move it to the System Application Folder or your Personal Application Folder if you wish, but it’s not necessary
@Daniela, if you are able, can you download and run this version to see if you are seeing the error with this version?
Once I get some testers and it works fine, I’ll submit to the devs for inclusion in the downloads.
I’m not an usual RT user, so quite superficial feedback: nevertheless the program seems to run normally, imported image moved it around, applied some changes and “effects”, exported. All seemed good.
BTW I take this opportunity to thank you for the Gimp builds for osx =)
