They will go back to a Mac zip distribution when they do an official release of v108 (or v109). v108 is currently in beta, not official.
You can get the v108 stuff by simply copying the AGK/IDE directory to your Mac and deleting the Compiler, Editor, Help and Utilities directory.
And you can get v1085 Tier 2 templates from the
AGK Wiki Templates page.
I just got the v1085 Player compiled and running on both my iOS 5.1 iPod Touch and iOS 6.0 iPad 2. It is important to change the Architectures under the Architectures section under Build Settings for the agk_interpreter Target to only armv7. Remove all reference to any other ones.
