Here's how I get Linux to install on my 2009 Apple MacBook Pro with an Intel Core 2 Duo CPU. It has the same limitation yours does. Do NOT plug your Linux USB flash drive into the Mac. Press the power button while holding down the Option/Alt key. After you see the grey screen listing all the available boot drives, then plug in your flash drive. A new bootable drive image should pop up after a few seconds. You should be able to boot Linux. I installed MX Linux months ago, and it runs great. This trick only works on those weird Macs with 64-bit hardware and a 32-bit boot loader.

I'm surprised OpenMandriva is your distro of choice, that's quite special; my favourite is Solus lol

Oh man, How I miss Snow Leopard.  I miss the days when I plugged any hardware into my mac and it just worked.

Hey Linux user here!
I would try XFCE on that thing, while it looks outdated out the box, it would sure make your systems resources happier and it's just as easy to customize!

Found this randomly from the youtube recommendations. I remember years ago installing linux on a Mac Mini 1,1 that had a 32-bit intel cpu, it has the same 32-bit EFI problem it seems as the early 64-bit machines. I even remember running the same patch to remove the EFI loader from the ISO. Excellent video, subscribed :)

By installing Windows 7 Ultimate I managed to run the Windows 10 installer - which wouldn't boot on its own - from within Windows 7, and my Mac Pro 1,1 is now running Tiny10 Pro without a hitch. I use it as an entertainment system, actually

I'm very glad to have found this channel in the first 7 months of its life. Keep doing what you're doing!

As far as I remember the firmware was 32 bit even though the hardware was 64bit compatible. I think you can flash the firmware from something like a 2,1 which more or less is the same underlying hardware as 1,1.

Thank you for showing the commands you used on screen rather than just mentioning what you did and moving on! That's a detail often left out in these types of videos that can help many people like me who have a hard time finding examples of what exactly to type.

the youtube recommendation is so worth it, subscribed

I love how literally everyone is trying to run DOS or even Win9x on a Mac.

I myself actually have, but I have the worst problems on my 2014 Mac Mini: DOS 7.1 installs fine, but as soon as I boot into it, FILESYSTEM CORRUPTION HAVOC. And yes, Windows 95 OSR2 has the same problem.

Also, Mac Pro 1,1 is 32-bit EFI, not even UEFI. (this machine actually predates UEFI by a couple years) There's a patch that people do with the 1,1 which is to install the 2,1 firmware and therefore get 64-bit EFI, eliminating most of the issues seen in this video relating to Linux EFI.

You're correct about Steam being broken from GPU driver issues, you're very much expected in the modern Linux era to have a Vulkan capable GPU, especially for games running through Proton. (though it could also be the Xeon missing instructions needed by current games)

I just so happen to have gotten a similar 2006 iMac recently, and I was also having issues getting Linux to boot. It's like you made this video just for me! Thank you.

Awesome to see life being brought back to the old Mac Pro 1.1! Love these restoration journeys

An interesting video!👍👍
Some of those problems occurred when I tried to install Linux Mint and other Linux Distros on three HP 64 bit laptops, but Zorin OS installed and worked.

2:18 sound like dr. Who theme song:)

You can tell a Mac Pro from a G5 right away by the dual optical drive slots :) I miss my 1,1 ... ran it from 2006 to about 2010 when I had to sell it for financial reasons. It was a beast, but now M1 totally stomps it while consuming the power of a nightlight

So cool dude. +1 sub.

yoo: i have one of these flashed to 64 bit with 32gb ddr2 & 2x 4 core cpus at 3gthz! i managed to get win10/linux and a bunch of other oses to work using bootcamp in macos then installing the os to an ssd on a different pc: voila!
ps: i added an RX 480 8gb in it too using the 2x6pin-8pin adaptor!

supertux aka god's gifted game thank u for running it on 2006 hardware

You need way more subs, this is great.

Random tijdlijn aanbeveling. Leuke video, blijf hobbien!
