I've been using MYOB AccountEdge since June of 2001 when I started working for myself. I believe it was the first non-Apple MacOSX native applications I used and one of the first available. It is my belief that Apple gave MYOB a pile of money to port the application to MacOSX when Intuit didn't jump to update QuickBooks (which is still a pile of garbage on the Mac, from what I understand).
While MYOB has been adequate to my needs that's about the best you can say about it. The interface is very cumbersome, it is finicky to customize it has a whole lot of features that I don't need, but worst of all it is a resource hog. For reasons I don't understand launching AccountEdge causes the CPU time of LaunchCFMA to jump up to 45% and WindowServer to 50%. This persists even with MYOB in the background.
The final strike against MYOB came with the upgrade to Leopard. There is at least one hanging bug involving printing that is a deal breaker for me.
At this point I am trying to decide between Billings, iRatchet and TimeNet. I have already decided against iBiz because of complaints about data integrity.
More here as the evaluation progresses.
