On one of my machines I run OS X 10.6. I recently ran into a situation where I needed to print from that machine to a Brother HL-L2360DW printer. Brother has evidently stopped advertising that they support 10.6, or they have stopped testing their products against 10.6. It is understandable. It is an older operating system.
To get the Brother HL-L2360DW to work via USB from OS X 10.6, I updated the firmware on the printer (via the Java based app brother provides). Then I downloaded the 10.7 full driver install package and installed it. It ran the installer no problem. After the installer was finished the HL-L2360DW CUPS driver was found and the printer was able to work with duplexing.
So there you have it. The Brother HL-L2360DW does work with OS X, at least via USB.
