"The application LOGINserver quit unexpectedly" every time you login


Everytime you login, you get the following message:


This is caused by incompatible drivers from a Brother multifunction / all in one printer scanner.


  • If you use a Brother device with your Mac, then more support is available here.
  • If you don’t have or no longer use a Brother device:
    1. Go to your main hard drive (usually Macintosh HD).
    2. Open the Library Folder.
    3. Open the Printers folder.
    4. Delete the Brother folder.
