I just installed the Squirrel keyboard input for typing Chinese characters using Jyutping on Mac by following these instructions:

The instructions are pretty self-explanatory, the only thing I had a bit of trouble with was finding the Squirrel menu, it's in the top menu bar on your screen where the keyboard inputs are (with little flags, for example the Canadian flag for Canadian English, or the Québec flag if you use a "French Canadian" keyboard.) It doesn't work properly if you skip step 4, by the way. Hope this is useful for someone!
