I recently had a situation where I wanted to uninstall a Brother TWAIN driver and rollback to an earlier version on my MBP (OS X 10.6.8). I found instructions on the Brother web site and followed them to the letter. However, I was unable to reinstall the older version (freshly downloaded from the Brother web site) - the installer provided a message indicating that a newer driver was currently installed on my system.

I ended up manually reinstalling the older driver by going into the DMG and extracting the files.


  1. Are there any other locations that I should have looked to remove files from the newer Brother TWAIN install?
  2. Are the Brother uninstall instructions complete?

This question came from our site for computer enthusiasts and power users.

They should really offer an uninstaller.... – lemonginger Sep 8 '11 at 0:20

To answer both questions at once, it seems that the Brother instructions only cover system level files. This will not remove any files that you as a user created or installed. I would go through the instructions again, then repeat the instructions, but for every location where it says "Macintosh HD > Library > x", I would also check at "Macintosh HD > Users > YourUsername > Library > x".

It is also possible, depending on what version of OS (I see that you are rolling back to 10.6.8 - does that mean you were on 10.7?) that they are system installed. I wouldn't recommend removing anything from your system folder, but it may be finding the drivers under "Macintosh HD > System > Library".
