I just recently purchased a new iMac and installed CS6 again. When I went to the update page to reload DNG 8.5 it went into Applications when downloaded and it appear I have to open it and select the files, etc. On my old iMac with the same CS6 after I downloaded the DNG update, when I opened Bridge and photo uploader opened it did the conversion immediately. Why has this changed or have I done something wrong with the new download?
Are you wanting to convert to dng because the Panasonic GH4 files won't open in photoshop cs6 without converting them to dng first?
Photoshop cs6/Bridge cs6 should be able to be updated to camera raw 8.6, provided your mac os x is newer than snow leopard 10.6.8
(Help>Updates from within photoshop cs6)
Not having a updated camera raw plugin could be the cause of why the photo downloader doesn't work as on your older mac.
Thanks! Worked perfectly!
