I run Macs with OS 10.6.8, use Adobe Bridge CS5 version 126.96.36.199. My work flow is to put a card in the computer, open Bridge and use "Get Photos From Camera" which opens Adobe Photo Downloader. I convert them to DNG's, put some copyright info in the metadata and write them to a folder of my choice. Since I upgraded ACR to 6.5, when in Adobe Photo Loader I try to chose a folder to write the files to, it freezes. I went back to using ACR 6.4 and the problem is gone. Fortunately I don't have a camera that needs 6.5 so I'm ok for now.
