Hi, we're out of luck, it cannot run on G5s.


10.5.8 is as high as any G4/G5 can go.


10.6.x/Snow Leopard General requirements...


* Mac computer with an Intel processor

* 1GB of memory (I say 2GB at least)

* 5GB of available disk space (I say 30GB at least)

* DVD drive for installation

* Some features require a compatible Internet service provider; fees may apply.

* Some features require Apple’s MobileMe service; fees and terms apply.


If it's a core Duo & not a Core2Duo, then it'll only run in 32 bit mode.


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 6 GB

• 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 50 GB.

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.
