To be able to easily fix this problem in the future I created an installer package that installs TWAINBridge.app in the proper location. TWAINBridge.app is located in /System/Library/Image Capture/Devices/. Lucky as we are, we can use the TWAINBridge from Mountain Lion in Mavericks, and continue to use our old TWAIN scanner drivers. Unfortunately, this meant that my scanner, a Canon Pixma MP800 multifunctional, which comes with a TWAIN driver, would not be usable for me on my updated systems.Īfter messing around a lot, I figured that TWAIN support in the previous OS X versions was done through an “application” called TWAINBridge. In this version OS X removes the support for TWAIN scanner drivers.
So I updated my computers to OS X Maverick.
