MacPro5,1 (2012) issues with installing OS X Mavericks

I recently got a 2012 Mac Pro off FB marketplace , the seller mentioned he upgraded the CPU’s , RAM (96GB) and GPU (NVIDIA GeForce GT 730). I tried to install Mavericks via a bootable USB (using Wowfunhappy’s website), and the OS loaded for a bit, froze, and then restarted.

Would this be a GPU problem ? since whilst the GPU did support Mavericks and even Mountain Lion , it needed a driver to be installed , so if it is the GPU’s case , is there a seperate install file with the drivers integrated ??
 
Can you try turning on verbose boot? I always forget how to do this on real Macs, but I think you hold down cmd-V at startup?
 
My apologies for only seeing these now!!

Anyways I don't think its a GPU issue... I tried El Capitan, which had the same issue, and Sierra refused to get to the second install phase... It only works on High Sierra onwards, (I'm running Mojave on it right now)
 
Freezes like that could be hard drive related - maybe try booting from a DVD or USB drive. You could even try a version of Linux to see if it fails. If it does, it is hardware related. Always first try to reseat the RAM. If Linux loads, might be a faulty hard drive or OS needs to be reinstalled.
 
My apologies for taking so long!! I was using Mojave on my MP5,1, but the Mavericks cravings got too much…

Anyways I tried verbose boot like, 3 times. Every time it either froze or restarted here…

Weird. You're actually very far in the boot process, past where I would generally expect things to get stuck.

It's probably a red herring, but you've presumably also noticed those NTFS messages. Is there any chance you can disconnect whatever NTFS disk you have?

Those are for my Windows 7 and my archives of my fav shows. This was happening even before I installed Windows 7, ill try disconnect the other drives and see how it goes!

I can’t even get in the installer, but I’ll try this on Mojave with the internet off, then reboot into the installer.

You need to seat back the date running a regular boot - then boot from and run the installer. (Edit; I guess that's what you said.)
 
Just tried it, nothing. Same error…

This is such a weird issue, considering my 2014 MacBook Pro, 2011 MacBook Pro and 2009 MacBook all work with the USB. Even myHack (Hackintosh software) recognises it as a valid Mavericks installer!

[Scene: Wowfunhappy is staring at this text, thinking to himself.] High Sierra, High Sierra... what changed in High Sierra?

I vaguely remember something about some types of storage only supporting High Sierra and above, irrespective of the filesystem (ie not APFS related).

What would happen if you disconnected every hard drive? Can you reach the installer?

While you're at it, maybe try disconnecting other hardware as well. Because obviously, there is something that Mavericks doesn't like. Heck, take out some of the memory sticks, if it's not too much trouble.

I tried the hard drives, no dice.

I tried removing the wifi, since (as much as I hate AI, it had my interest) the AI Overview on Google said it might be wifi related, so I tried disconnecting the card. It crashed even earlier!!

Also I managed to get Sierra working, however I tried El Capitan, Yosemite and Mavericks. All crashed. (I have yet to try Mountain Lion (not gonna bother with Lion and Snow Leopard, since the GPU is WAY too new for those.)

Gonna try decrease the RAM from 96gb to 32gb… Gonna have to undo my entire setup again because my optiplex is in the way
 
I have come to a realisation: I am an idiot.

I have a Kepler GPU. That requires a web driver.

No wonder it wouldn’t boot.

Although it doesn’t explain it for Yosemite onwards…

Hmm. Not all Kepler GPUs require Web Drivers. The GTX 780 (non-Ti) does not, for example.

Can't seem to find information for your specific GPU in a quick search, though.

Anyway, the Mavericks nVidia Web Driver should support it if anything does. And I wouldn't really expect this to block boot?
