I see that the author misses the older Mac UI, in which case they might like helloSystem, which runs FreeBSD underneath.
There’s not much meat on this bone other than “the scrollbars aren’t lickable anymore” and “btw I bought a ThinkPad and installed FreeBSD”.
If the author doesn’t like the current macOS scrollbars, they’ll be really disappointed once they try something other than xterm…
On macOS there’s a system setting to turn scrollbars back to a sane behaviour (always present, visible, size that you can hit with the mouse without too much effort). It’s a shame that this isn’t the case on other systems.
