(This is just to help macOS Finder users, not to say, "Well, Finder can do it too!!)
You can select multiple files in Finder > Right-click on one of them > Rename. That'll bring up a modal with some bulk-rename options, including a name pattern. It's not intuitive, but was really cool when I found it for the first time!
That's awesome! I use a Mac-based software similar to TC (after years of using TC on Windows), and always use it for bulk renaming. I had no idea I could do the same with Finder, I'll definitely take advantage of that in the future!
