They literally do. Since 10.9, before paging to disk, they try compress the memory instead.

As do Windows and Linux. Just in case someone takes this as a serious argument in favor of Apple :)

Just to nitpick, on Linux it depends on your distribution (or yourself) having enabled zram; some modern distributions enable it by default on recent releases, but yours might not have.

And for anyone who is on a distro who hasn't IMHO you absolute should enable it yourself on your personal machine unless you have 128GB or something.

I’m using Pop!_OS 22.04: how can I go about checking if this is enabled and enable it if not?

Says here it's enabled by default now https://www.reddit.com/r/pop_os/comments/104kbs4/zram_now_en...

You can run 'zramctl' to see the current status of the zram devices.
