“MusicBrainz Picard.app” is damaged and can’t be opened. You should move it to the Trash. This mostly seems to happen after moving the file to the Applications folder and seems to be caused by Gatekeeper mistakenly marking the app as damaged. To solve the issue open a terminal and run. Picard is an open-source cross-platform music tagger by MusicBrainz. It has the ability to identify audio files even without any existing metadata. Picard helps you organize your music collection by renaming your music files and sorting them into a folder structure exactly the way you want it.
This guide details the process I've used to build Tiger-compatible Picard app bundles on macOS. There are many ways to achieve this, but I've found these steps to be the simplest and most compatible after much trial and error. Burn for mac free download.
This guide was tested in a VM running Leopard. If you're using anything above Snow Leopard (Lion, Mountain Lion) you won't be able to install XCode 3, so this guide won't work. Apple el capitan download.

There are a lot of architecture issues in MacPorts that took days to debug. After working around those, Qt4 had broken functionality, such as drag and drop from Finder not working. Qt4 takes an entire day to build on my machine, whereas the precompiled Qt package from Nokia works just fine. The rest of the dependencies will be installed manually to /usr/local.
- XCode 3.2.6, with the 10.4 SDK installed at /Developer/SDKs/MacOSX10.4u.sdk (it's a selectable option in the installer).
- Python 2.7.3. Since we want compatibility with Tiger/i386, make sure to install this one: python-2.7.3-macosx10.3.dmg. Use the provided Update Shell Profile.command to make this your default Python. Note: this is required. You can't use the system Python that comes with macOS! py2app won't allow you to build standalone app bundles with it.
- Qt 4.7.3. Install this one: qt-mac-carbon-opensource-4.7.3.dmg. Qt 4.8 and up no longer support 10.4/Carbon.

New edge browser. Make sure /usr/local/bin is in your PATH, and have the following variables set in your .profile or .bash_profile (or do it manually):
Make sure you're using gcc 4.0.2. On Snow Leopard, I had to change the symlinks, because setting CC= didn't work for some dependencies. (I did this, but for 4.0 instead of 4.2.)
Now you have to install a bunch of dependencies by hand. Or, that's what you would have to do if I hadn't written this super-convenient (hacked-together) script for you: build-deps.sh. chmod +x and run from an empty directory.
I have no doubt the script will break somewhere for someone—help me fix it. :)
To enabled AcoustID fingerprinting in Picard, you also need the fpcalc binary. Download that from here and place it in /usr/local/bin.
Finally, you'll need two Python modules: py2app and mutagen. Install them manually or just use easy_install. Be sure to install them for the correct Python version!

Create the file build.cfg in the source directory. Mine looks like this:

Now we should be able to build a Picard app bundle. This requires a few commands, so I use a bash script to run them all:
Musicbrainz Picard Mac
If all goes well, you'll end up with an app bundle in the dist directory. We're done! Yay!
