Netkas method of updating to 10 5 5
However remember there's also a (many Code Resources - symbolic links IMHO) permissions differences you can ignore and that will not really be repaired (as I mentioned before and this is not new to 10.5.8).
Personally I am not RP fanatic and generally only do so if there's a related problem.
There are many Articles around the web that describe how to install OS X on a normal PC.
But there is no full guide who describes how to update 10.5.1 to 10.5.4. Upgrade 10.5.1 to 10.5.2 Update 10.5.3 to 10.5.4 Just start the Apple Softwareupdate, download and install the 10.5.4 update. If you’ve any problems write a comment and I’ll help you!
of course it’s all for intel core 2 based cpus and intel mobos.
The whole idea of upgrading a Mac Pro 1,1 for me started out of a curiosity: I began researching how to use the n Vidia 210 Silent video card (with no native Mac drivers) in my Mac Pro 1,1 and was disappointed after many dead-ends, finding no readily available answers, but I refused to give up.
Many who I chatted with and messaged during my search for answers claimed it just wasn’t possible to use the n Vidia 210 in a Mac Pro 1,1 without running Chameleon or other hackintosh tools to get OS X 10.8 Mountain Lion or later installed (a necessity for using the n Vidia 210 but not technically possible due to the 32-bit EFI issue), which I found disappointing to say the least.
After all, this was a genuine Mac Pro and not a hackintosh build.
After a great deal of persistence, I was thrilled to eventually find a native upgrade path (again, many thanks to Tiamo at Mac Rumors) that is not that hard to accomplish.
