I put Ubuntu 23.04 on my old 11" Macbook Air, and it's much awesomer than I expected

Dave@ActionRetro what do you reckon is the oldest Mac that modern Ubuntu will run on?
benedolt@sudoaptgetlife @ActionRetro You can run Ubuntu on all Intel Macs. (Haven't tried the PPC ones...) In my pile of laptops I have a MacBook from 2006 running Ubuntu 16.04. (The very first MacBook revision is 32-bit only, so upgrading isn't an option.) It works but it's not really usable for e.g. webbrowsing.
I also have a 2010 Core 2 Duo MacBook, the white polycarbonate one, and that runs Ubuntu 22.04 perfectly and is still very usable! Just don't expect 4K Youtube to work. :D
@benedolt @ActionRetro I have a late 2007 Macbook which i believe is also one of the 32-bit models. The newest OS i've got running on that was Windows 10 through boot camp. Haven't tried any Linux distros on it yet.
@benedolt @ActionRetro If i remember right it was not happy running 32-bit Win 10 so i just restored the boot camp partition back to Win 7 and left it at that lol.
@sudoaptgetlife @ActionRetro If I remember correctly, only the 2006 MacBook is a true 32bit machine. Starting with the second revision in 2007 the MacBook is actually 64bit capable, but the EFI is still 32bit-only, so you have to use a 32bit bootloader. That's doable, but it's bit tricky... And obviously it's too much for Windows 10! lol I wonder how fast win10 would run, if you'd get it to boot...
@benedolt @ActionRetro tbf its within the system requirements for win 10 32-bit (barely), I'm pretty sure it did boot but ran like shit, basically exactly as you would expect with the spec available.
I think it was ok just navigating the OS but as soon as you try to do something that requires more cpu or gpu power than it has available then it would have problems.

@sudoaptgetlife Interesting! Yeah, I'd expect it to run really badly - but cool that it boots at all!
