Following is my original 5 star rating. But, the app has totally ceased to function since el Capitan and still does not work now, May of 2016.
So, after 30+ years, I’ve moved from Windows to Apple. The prospects of Windows 8 plus my last two years experience with iPhones drove me to it. But, my new Macbook Pro won’t show me date taken or a lot of other Exif metadata from my thousands of photos and it does not allow me to easily rename batches of photos. I have filed my photos by "date taken/subject/id#” for ages. What can I do? Thankfully I found Better Rename v.9. It does it all exactly the way I need it, quickly and easily.
Okay, if you are an OSx newbie like me, there were a few problems. Nothing worked. Select 500 photos in a folder, set up the app to rename them, and, BAM, I am asked to re-enter my administrator/usesr password for each and every one of the photos! This is Mavericks doing this, not the app. So, I close the app and go to the folder level, unlock it, change the permissions to let everyone read and write and tell it to apply this to “enclosed items”. Doesn’t work. Tried selecting all the photos and changing their permissions ala Windows. Won’t let me. Won’t let me unlock them without entering my password for each one. Finally, I found that, while Mavericks doesn’t tell me its doing it, it was apparently making the changes I selected, silently and secretly, in the background. Once I found that Mavericks may be doing things slowly and without telling me, I realized that Better Rename was doing exactly what it claims to do and doing it well. I have now changed thousands of names with no further problems and have no worries about the thousands left to do.
Now, I just have to find the right app to see ALL the Exif metadata and to change or delete it for pics I may want to make public. There seem to be more faked apps in those categories than there are reliable ones. But, after many nights of working with my photos, I find Better Rename to be just great.
