MacBooks made great Linux machines for many years before the bad times started. And hopefully will again some day!

Microsoft for years tried to act like a good guy with Secure Boot standards that promised systems would remain general purpose computers. If Microsoft obeys it's own standards, that should be the case here too! If not, how can we expect other vendors to provide the general purpose computing systems Microsoft has promised to keep available, as they locked down the boot chain?
