To comply with labelling laws, the fast food chain will change its menus across Australia.
The new display boards were found to be breaching labelling laws by not showing how many kilojoules are in each item.
"We are fully supportive of kilojoule labelling as a way to provide our customers with information to help them make informed choices," McDonald's spokesman Chris Grant said.
"In consultation with the NSW Food Authority we have proactively made some edits to our new digital menu boards to enable additional comparison between products. The changes will be in our restaurants nationally within the next couple of weeks."
"Kilojoule information is also available in a number of different places for our customers, including on digital order kiosks, our mobile ordering app, in-restaurant and drive-thru menus as well as our website."
