I need Rosseta firmware for my iMac

I have a Brother MFC. I received a message that I will need Rosseta firmware for the next upgrade of the ios. I have looked all over Brother's site for the upgrade and can't find it. They don't show any "contact us" info so I can ask them. Is anyone else looking for something similar? I am running Mac OS Tahoe 26.6.2. My iMac is a 2021 version with a M1 chip.

iMac 24″, macOS 26.6

Which model Brother MFC please. Many Brother model multifunction devices are AirPrint-enabled and do not require drivers. If it requires a driver that requires Rosetta, it will continue to work with macOS 27 "Golden Gate".


Excerpt from Using Intel-based apps on a Mac with Apple silicon - Apple Support:


Rosetta is currently available for any Mac with Apple silicon, and it will remain available through the forthcoming macOS 27 — the next major macOS release. Starting with computers using macOS 28, Rosetta functionality will be available only for certain older, unmaintained games that rely on Intel-based frameworks


Generally speaking if a printer or MFC requires manufacturer-provided drivers, it remains the responsibility of the device manufacturer to provide and maintain them. That imposes ongoing legacy costs long after the device was sold, with zero return. Nobody does that.


Depending on the Brother device's exact model designation workarounds may exist.

Rosetta is not firmware. It is software provided by Apple. If Rosetta 2 is not already installed, and you try to run a Mac application built for Intel processors, your Mac will offer to download Rosetta.


Apple plans to drop support for Rosetta 2 in macOS 28. So, under macOS 28 and later, Intel-only applications will become as dead as doornails. For now, you may get warnings when you run Intel-based applications under Tahoe and Golden Gate, but you will still be allowed to do it.
