I got a MacBook a few weeks ago, first Apple computer I have ever owned. I was so surprised when I plugged my 4K monitor into it, there didn't seem to be a way to run it at native resolution and all the text was aliased.
Text is blurry on those as a result.
Thankfully, my desktops all run x11, so Apple’s fractional scaling brainrot hasn’t spread to my Linux or BSD’s yet.
