Exif Everywhere for Mac OS X aimed to display and strip Exif metadata, GPS geolocation and other properties of JPEG, TIFF and RAW images. It is a set of Safari, Firefox and Google Chrome browsers extensions and a Standalone Application.
I understand the app is now discontinued (which is a shame, by the way).
But that's no reason for the app to refuse to acknowledge the license I bought, for, according to the developer, "the key is used on another computer".
I love Exif Everywhere, that I mainly use as a Safari plugin. Sometimes, however, I use Firefox, which is meanwhile up to version 13, whilst Exif Everywhere only supports up to version 5 or so? When is an Exif Everywhere uptdate to be expected?
