Hi!
This tool can be downloaded from the member center and it's linked from this page (https://developer.apple.com/fonts/). We rely on it to use ftxdumperfuser to be able to modify font attributes in a text editor.
I had installed this a long time ago but OS X El Capital can't find it so I re-download it, but when trying to install I get a warning that tells me that the package might harm my computer or that the installation can fail. Effectively failed. Is this because of Sytem Integrity Protection?
Any ideas if this tool will be updated or if there are any alternatives?
Thanks!
