I would recomment the Canadian French keyboard! The letters are at the same place as the qwerty one, but you get French accents. The question mark, apostrophe, etc. also move. Not sure how to get it on a Macbook though... :)

here is the french layout https://en.wikipedia.org/wiki/AZERTY It isn't a good idea to use the incorrect layout for your computer. The different layouts don't just rearrange keys but also have different numbers of keys and different approaches to typing special characters. I suspect that you may have an american layout which is one of the few layouts that is supported for input styles such as pinyin. there isn't really a necessity to install a french keyboard you can typically type the special characters on most layouts you just need to use key sequences. so for on most pcs press ´followed by o to get ó, ` followed by o to get ò, ^ followed by i to get î here is a guide I found for macs http://symbolcodes.tlt.psu.edu/bylanguage/french.html#macaccent

Used in Belgium, France and a couple of African countries,

It's the European keyboard layout :-).
