Can a MacPro 1.1 be upgraded to High Sierra, to enable it to run more recent software. It is currently running on El Capitan
Thanks

Then your Mac Pro is not likely to be a 1,1 at all.

what model is it really? (if you post a screenshot try not to include the serial number -- it attracts vermin.)
If your Mac Pro really is a MacPro 1,1 from 2006 or 2007, you have already applied a substantial hack to get beyond its official limit, 10.7.5 Lion. it will be very difficult to get farther.
Sorry, NO.
windows 10 Boot Camp requires:
Mac Pro introduced in 2013 or later
It also clobbers your EFI partition if you attempt to run it, so make sure you have a trusted backup before you fiddle with it.
Ok.
Possibly the previous owner may have done the hacks.
I should be able to boot camp Win10 on it though, right? My software can run on Windows if I can’t upgrade the Mac OS
Thanks for the response.
Actually I haven't hacked the system at all, just did regular updates.
My software requires at least High Sierra to run, so I was wondering how to install it, since I couldn't install through the App store.
Wondering if a GPU upgrade will help
OK. Thanks again
I assumed a Pro 1.1 based on the system info (see attached screenshot)
Ok. Thanks a lot.
You’ve been most helpful.
Currently, the system is useless to me so there’s nothing to lose by tinkering a bit with it.
Will let you know how it goes.
Cheers
So it appears someone, somewhere along the line applied a hack that extends the firmware to a later version. This expanded firmware does not fit in the built-in ROM, so the excess is loaded into system RAM, and may appear as if it were a custom EFI or custom boot-loader.
I recommend you be very careful with your boot drive, and have a complete clone of it on hand. If you lose the image on your boot drive, it will take some work to re-apply those hacks.
But no, that computer can not go any farther than 10.11 El Capitan.
Can I upgrade a MAC pro 1.1 to run High Sierra or Mojave
