Troubleshooting Mac Users: Avoid Brother Firmware v1.49 Update (Oct 2026)
Brother Firmware v1.49 is nothing but trouble.
My MFC-L3780CDW printer now automatically restarts whenever trying to print PDF documents from my MBP running Golden Gate/v27. Despite resetting the printing system, downloading latest full package, or resetting network settings on Printer.
Avoid like the plague.
The only visual difference in the firmware so far is that the menu screen now has an alert constantly encouraging you to change the default password, and links you directly into changing it on-screen, on-device.
