"The application LOGINserver quit unexpectedly" every time you login

Problem

Everytime you login, you get the following message:

Cause

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

Solution

• 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.
