Hello,
I've been using the method on the Der Flounder blog to capture the GarageBand 10.0.2 package from an AppStore install. However, every time I install using this captured file I get the error that GarageBand is damaged. Are people now needing some other method for getting and distributing the latest GarageBand app? I've tried capturing the GarageBand app on a few different computers. The resulting file has always been the same size and checksum: 985.9 MB as shown in Finder.
