I am running 10.6. Chromium Legacy is for 10.7 and above, and the same is true of a lot of software. Meanwhile, on my Linux partition, I can have Firefox Nightly if I want. It’ll run heavily, but it’s possible.
As it happens, I do have a somewhat recent browser installed in OSX, but it’s not great.
Also, running an older OS like that isn’t a good idea, as it won’t have received security patches or microcode updates.
That’s the thing, you can run a 64-bit distro as long as you’ve a 32 bit grub starting it :)
I hadn’t quite considered that somebody had implemented this. Thanks for the info!
There was also another user who gave me a link to some software that modifies mixed-mode ISOs so that they will boot on my potato laptop.
