65" QLED Q9FN with Xbox Series X. Worked for me. Thanks for this!
1) Make sure you have the exact firmware update for your tv, don't just blindly follow the link but type in your model and look it up, that was my first problem. I followed link above and blindly followed but TV will not recognize it if its not the EXACT firmware for your TV.
2) I use a mac, so I learned through trial and error that I had to erase and reformat my usb drive to MS-DOS (if using 32Gb and under, exFAT if using over 32Gb) using Macs disk utility.
3) Once the file is downloaded and your usb is erased and reformatted appropriately, unzip the file.
4) You'll want to drag the entire folder as is to the empty usb drive. I learned this the hard way as well only dragging the exec. file over within the folder. Doesn't work. Just drag the whole thing and copy it over.
5) Plug in the usb drive to the one connect box and on the TV go to settings>support>software update>update now and your update file should be found.
Hope that helps someone else with a mac. It took me a few hours of digging and trial and error to figure this out but it immediately recognized my Series X as "XBOX" and auto low latency mode was un-greyed and available. I will say that I still can't get it to come out of Game Mode with apps like Disney+ and Netflix as of yet, but will do some more testing.
