PIXMA PRO-100 Unable to access remote UI

[vsinfleurs]

Hello. I purchased from someone Canon Pixma Pro 100. I have Macbook Pro. I am not able to access REMOTE UI on my Macbook Pro, I probably does not know how. Can someone help me? I will show screen shoots. It asks me for username and password. I also does not know how to custom size of the paper. I have the Canon QUICK Menu, but I can't see anything about customing the size of the paper. Everything seems more difficult on Macbook than on Windows
