Planned deprecation of OS X 10.5 Leopard

This month marked the first time that OS X 10.7 Lion users of our products have been the majority. In total, 91% of our users are running OS X 10.6 or 10.7. OS X 10.5 users make up less than 7% and this number is falling steadily.

With the changes Apple is making to its developer tools, it's getting harder and harder to provide features to users on the latest operating systems while maintaining backwards-compatibility with Leopard and PowerPC users.

We are therefore announcing that we will be withdrawing support for OS X 10.5 Leopard within the coming months. This also means that we are withdrawing support for PowerPC computers, as 10.5 is the latest OS they are capable of running.

All new products will require OS X 10.6 or higher and existing products will be gradually transitioned. Leopard users will always be able to download the latest 10.5-compatible version of a product but they will need to upgrade to OS X 10.6 or higher to access newer versions.

We'd been planning this announcement for a while but with the unveiling of OS X 10.8 Mountain Lion today it seemed to be the right time. Overall we think the new OS is a positive thing that provides many useful tools under the hood and we're keen to take advantage of its features.
