The development timeline, poor performance and recent lack of updates betray a failed business plan. In an attempt to capture a larger share of the Mac market by updating a successful product the company has bit off more than it can chew.
It appears that Rootsmagic is little more than a garage operation with only 3 identifiable employees - far too few to support an effort of this magnitude. This was evident when they failed to appear at RootsTech - a premier marquee event for all genealogical software.
Their pricing history on previous versions (too low) has failed to accumulate sufficient cash to hire the manpower necessary to support this update. This has resulted in a delayed and disastrous product introduction which was partly rescued by a rapid series of updates. Unfortunately, the updates have slowed to a crawl and customer frustration has mounted. Its not clear that they can reverse this death spiral without a cash infusion to hire the required programmers.
Don't be surprised if Rootsmagic changes hands or, worse, ceases to exist.
