Hi, You understood perfectly, but Apple seems a bit secretive as to what is required, & many Macs can't run ML/10.8, but may run Lion/10.7.
(For my money, OSX went really down hill fast after 10.6.8)
Snow Leopard/10.6.x Requirements...
Lion/101.7 System requirements
• x86-64 processor (Macs with an Intel Core 2 Duo, Intel Core i3, Intel Core i5, Intel Core i7, or Xeon processor.)
• At least 2GB of memory, (I say 4GB)
• Latest version of Mac OS X Snow Leopard (10.6.8), with the Mac App Store installed
• At least 4GB of disk space for downloading, (I say 40GB at least)
Like Snow Leopard, Lion does not support PowerPC-based Macs (e.g., Power Macs, PowerBooks, iBooks, iMacs (G3-G5), eMacs).
Lion also does not support 32-bit Intel Core Duo or Core Solo based Macs. Rosetta is no longer available in Lion, which means Lion no longer supports PowerPC applications.
But you have to call Apple to get Lion/10.7 if it indeed will run it.
Macs that will support OS X 10.8 Mountain Lion
As usual, the newer the Mac the better:
• MacBook Pro – 13″ from mid 2009 or later, 15″ from late 2007 and newer, 17″ from late 2007 and newer
• MacBook Air – late 2008 and newer
• iMac – models from mid 2007 and newer
• MacBook – 13″ aluminum from 2008, 13″ from 2009 and newer
• Mac Mini – early 2009 and newer
• Mac Pro – early 2008 models and newer
• XServe – early 2009 models and newer
Macs that are NOT expected to support OS X Mountain Lion
Older Macs and those with weaker GPU’s will likely be left behind:
• Anything with an Intel GMA 950 or x3100 integrated graphics card
• Anything with an ATI Radeon X1600
• MacBook models released prior to 2008
• Mac Mini released prior to 2007
• iMac models released prior to 2007
• Original MacBook Air
This list of compatible and incompatible Macs and system requirements are based off of the first OS X Mountain Lion Developer Preview and may be subject to change, we will update when we learn more about the specifics. OS X Mountain Lion will be released this summer but presumably long before that we will know precise system requirements and what Macs are and are not supported by the new version of OS X. Stay tuned.
