I just tried installing mavericks on my mac pro 1,1 with stock 7300 gt 256mb and I used that ssoft terminal program to make the usb flash mavericks install for the 1,1 machine and and it booted right up and I started the install and about half ways a stops with a error message window, Error I got said something like "install failed, the software failed on this machine" had a yellow explanation point, something like that so I shut down the mac pro.
What you guys think is it because of the 7300gt 256mb card in it currently,or need to redo the ssoft flash drive? Thanks
Also another question with lion installed can a pc nvidia card like a gtx 560ti work with or without flashing the card in lion or does it have to be mountain lion and up?
That is usually a corrupted file error but could be a plethora of things. Just try it again, maybe even a few times if you need to. As for the 560ti, it will work in lion without flashing but you will not have a boot screen of course.
