This month, EveryMac.com features a comprehensive update to cover MacOS X 10.6 "Snow Leopard" compatibility details for each Mac -- including 64-bit, OpenCL, and Grand Central Dispatch support -- in addition to an all new MacOS X 10.6 "Snow Leopard" Q&A.

The "Maximum Supported Version of MacOS X" capability listing has been updated completely with a convenient single page run down of which Macs can support MacOS X 10.6 "Snow Leopard" and which ones cannot. Specific details regarding 64-bit, OpenCL, and Grand Central Dispatch capabilities are provided on the specs page for each Mac as well as within the MacOS X 10.6 "Snow Leopard" Q&A.

In addition to 64-bit, OpenCL, and Grand Central Dispatch details, the MacOS X 10.6 "Snow Leopard" Q&A covers upgrade options, performance, compatibility, and more. Everything from "What are the 'pros and cons' of upgrading to MacOS X 10.6 'Snow Leopard'? Is it 'worth it'? Is there any reason not to upgrade?" to "How much faster is MacOS X 10.6 'Snow Leopard' in 'real-world' tests compared to MacOS X 10.5 'Leopard'?" is answered in-depth.

If you missed it previously, be sure to also check out the "Ultimate Mac Timeline" feature that dynamically displays every Apple Mac -- from 1984 to the present -- in a scrollable, interactive timeline format [subsequently discontinued].
