Before fixing anything permanently, I think it is important to answer the
following questions:
1) What were those values in previous versions of Ubuntu?
2) Why were they changed in the current version?
3) Do current Macbooks work well with such settings?

If current Macbooks work well with such settings, it is necessary to find
out since what Macbook version the mousepad was changed. I believe it could
be since they merged the mouse pad and button together. Based on that, it
is possible to change the values based on the Macbook version as Klein
mentions using versions less than "Macbook x.y".

I am very interested in the answer to question (1) because, despite that my
mouse works well now, I think its operation was better ("smoother") in
previous versions, and I still have sometimes odd right-click behaviour.
