is there a way to batch change tags in folders?

I just discovered the same bug. I use tags a lot, but this folder has just over 100 items, which I tagged, but I now need to un-tag. But the contextual-menu method (control-clicking the selected files, then selecting the tag to be removed) is not working. Clearly a Finder bug.

Fortunately there's a simple solution:

After control-clicking the selected files, the contextual menu shows the rainbow-colored labels. Just above them is the word "Tags…" (The ellipsis—on any menu item—literally means "there's more to this command, and another window will open.")

After selecting "Tags…," a mini window pops up, displaying any tags currently assigned to the selected files. The cursor's already positioned after the last tag, so just hit delete, as needed (and/or click on new tags from the list to add them), then hit return (enter). Voilà.

What sort of tag are you wanting to add.

Are you going to use iPhoto to manage those photos. If you you an batch add keywords, descriptions and titles to the photos. Those metadata can be written to the image file if you need to use them outside of iPhoto.

If you're referring to tags for the files then you'll have to use a 3rd party app. Go to MacUpdate.com and search for "tag files" or something similar to see what comes up.

Select your files and use the gearbox in a Finder window to set the tag.

You had me going there for a bit, John. I had to hold down the Option key when I selected the gear before I got the Inspector option.

I just meant that you could select those files and then apply a tag to all of them in that same menu. I didn't know anything about the Option key or the "Show Inspector" (multi-file Get Info) until you mentioned it just now.

Duh! The Edit Tag button. 😕 Looked right at it I don't know how many times and it never registered. 😮
