Sure, but a new battery isn’t that expensive

Thanks! I thought the problem was the T2 chip and I thought the non touchbar macs had them too, but it’s been a while since I looked into this. I have a machine with a broken touchbar that could plausibly run something that isn’t macOS and was very disappointed when I realised I essentially had to install special distros with some kernel patch or something on it.

What do the v3 and v4 in the architectures mean?

This is a pity because MacBooks pro from ca 2013-2015 are great; cheap second hand because they’re out of support in macOS, good screens, excellent build quality and fast enough for anything you want to do with them.

I wouldn’t recommend macs in general. Anything with a touch bar (intels from ca 2018-19 and on) are tricky to get to run Linux at all, anything with apple silicon is very experimental, and the older models have Broadcom Wi-Fi that doesn’t ship with drivers on any distribution I know of.

One of my harder earned life lessons is it’s structurally impossible to run a company that develops and sells a product based on this kind of soft values and buying devices from them is almost always a recipe for disappointment. It doesn’t even have to be the fault of the company (though it often is)
