Running Concurrent Versions of iTunes

Tuesday, May 11th, 2010

In my forensics classes, I get a lot of requests for help to run two different versions of iTunes, as different versions provide different functionality and interoperability depending on the device and firmware version. This is a quick how-to to set up a Mac with iTunes 9 and iTunes 8.1.1 in such a way that you can run a simple shell command to switch between the two, with a reboot in-between. The following files/directories are specific to each version of iTunes. As a result, you’ll need a separate copy for each version you want to switch between:

  • /Applications/iTunes.app
  • /System/Library/PrivateFrameworks/iTunesAccess.framework
  • /System/Library/PrivateFrameworks/MobileDevice.framework
  • /System/Library/PrivateFrameworks/DeviceLink.framework
  • /System/Library/PrivateFrameworks/CoreFP.framework
  • /System/Library/Extensions/AppleMobileDevice.kext
  • ~/Music/iTunes

What we’ll do is install iTunes 9, move these files into an archive, then install iTunes 8.1.1 and do the same. Using symbolic links, you’ll be able to set up an alias to simply point to the desired version of iTunes.

Al Capone’s Original Thompson Machine Gun

Tuesday, May 4th, 2010

Just when I thought my trip to Chicago would be average, some of the sergeants at the Chicago Police Training Academy, whom I’m training in iPhone forensic investigative methods, took me to the firing range in the basement and brought out an old dusty case. What came out of that case was an amazing piece of American history – Al Capone’s original Thompson submachine gun. As each class member took a hold of it for a photo-op, an immediate sense of joy came across their faces. Just looking at it made me excited and anxious too, but when I saw the rangemaster loading magazines, I realized this was going to be more than just a lesson in history. He took me to the firing line, gave me a quick talk about its function, then handed the beautiful antique to me as the the rest of the class smooshed their faces into the glass to get a peek. For a relic, the piece shoots remarkably well, and is probably the smoothest fully automatic firearm I’ve ever fired. We riddled a few targets full of .45 caliber bullets, then emerged much safer than when the two cardboard cutouts were walking the streets.
