Check Mark doesn't seem to be interested in supporting MoneyWorks, which is an up and coming accounting package for OS X that is very promising. Stay away from Check Mark Payroll if you're a Canadian who wants to use something other than Connected Accounting or MYOB (both of which suffer from limitations in various areas).

I am returning my copy for a refund as per their return policy because they have refused to integrate with modern accounting software packages (i.e. MoneyWorks).

Their team was polite at first when I requested they look into making the two programs compatible, but they quickly lost interest in satisfying their customers as soon as it meant making any modifications to the exports their product puts out. They are going to go the way of the dinosaur with that attitude, IMHO.

Cognito, the makers of MoneyWorks, was very interested in assisting Check Mark with this change but were told to go away because there wasn't enough user interest. That is short-sighted and really an inaccurate presumption.

I can't reccommend anyone use this unless they don't mind being told which accounting packages they are allowed to use. Check Mark really wants you to buy the companion product, MultiLedger, and seems only interested in supporting users who are willing to buy into that. (I am not because MultiLedger is an ugly looking, feature-incomplete, poorly-supported program)
