Migrating Mail Rules to new computer

One last mail migration detail I’ll note here for the benefit of Google search and Mac OS Apple Mail users everywhere: Moving your Mail.app rules from an old computer to a new computer:

  1. On the old computer, locate the plist file for the old mail rules. You’ll find it here /MacintoshHD/Users/your_user_name/Library/Mail/MessageRules.plist
  2. Copy the file to the desktop of your new computer
  3. Quit Mail (on new computer) if it is running.
  4. On the new computer, locate the same Mail directory as in step 1.
  5. (optional, for super safety) Move the MessageRules.plist and MessageRules.plist.backup files to another location (not the same directory as the file you copied from Old Computer)
  6. Move the Old Computer’s MessageRules.plist file to the /MacintoshHD/Users/your_user_name/Library/Mail/ directory.
  7. Launch Mail; view preferences, and check that your Rules are there. Done!
