How can I rename the rigs on my mac?

Quote from horribleman

I guess I need to edit something in the file. I renamed the zip files but that didn't work.

Thanks for any advice.

Renaming the file in your computer both Mac or PC may render the profile useless.
So in short: You can't and you shouldn't.
You need to do it in the KPA itself (and wait for the long requested software solution as we all do).

You can upload the rig on the Rig Exchange (make it private if you don't want people to have it), edit everything you need then download it...this way you'll have an online backup of your own rigs as well!
