Last week, Family Tree Maker for Mac 2 showed up on the Amazon UK website. Here in the US, it's from Nova Development and supported through Ancestry.com. In the United Kingdom, it's from Avanquest Software and supported through Ancestry.co.uk.
The UK version is being marked as the "UK Version" and does include a 6-month "Premium Membership" to Ancestry.co.uk. It's also listed as the Platinum Edition if you are looking for an equivalent edition to compare to the Windows versions.
Speaking of Family Tree Maker, in addition to a nice new site re-design, Ben Sayer over at Genealogy Tools has also published a tutorial covering Adding Names in Family Tree Maker.
