I bought the SL upgrade last month and did clean install from Tiger. It works fine,but you dont get the fancy other stuff incl. in iLife like Garageband Iphoto ect. But if you can do without, I wouldnt bother, unless you have an extra 90 bucks burning a hole in pocket
I'm running a G4 PPC on OS X 10.4.11 Can I upgrade to SL?
No. You must have an Intel processor.
What about regular Leopard? I only ask because Amazon has it for sale and claims I can, but I want the truth not salesmanship...
If you want truth, all you need to do is visit Apple's site:
Apple - Mac OS X Snow Leopard - Technical specifications
For information on 10.5 - Apple - Support - Mac OS X 10.5 Leopard
What about regular Leopard?
For those who don't want to follow the excellent link and just want a quick answer: You don't need an Intel processor for 10.5 Leopard.
As many have speculated, Apple has added no technical limitations to the install process to prevent the $29 standard Snow Leopard disc from installing on a Mac running Tiger. The information was confirmed in an early review of Snow Leopard by All Things Digital's Walt Mossberg published late last night. "Apple concedes that the $29 Snow Leopard upgrade will work properly on these Tiger-equipped Macs, so you can save the extra $140" over the Mac Box Set, Mossberg wrote.
(emphasis added)If you have purchased an Upgrade for Mac OS X Leopard license, then subject to the terms and conditions of this License, you are granted a limited non-exclusive license to install, use and run one (1) copy of the Apple Software on a single Apple-branded computer as long as that computer has a properly licensed copy of Mac OS X Leopard already installed on it.
