No, I was under the (mistaken) impression that Linux on Mac is fine. It's not. Sorry about that.
No problem. I thought that as well until I had to boot linux on my mac for an SSD upgrade.
Witness the help pages organized by specific MBP version: https://help.ubuntu.com/community/MacBookPro yes, it is that complex.
Running Linux on a Mac is not a good idea. Just getting it to boot is a 4hr plus long endeavor. Best to run Linux in a VM on your mac. Windows on Mac is a better idea than Linux.
I think by "works well with Linux" in that it has a bash shell, has Homebrew, etc.
