MacOS High Sierra (10.13)

MacOS 10.13, which quietly switched the Mac's underlying filesystem to APFS — still a realistic target for genuinely old (2009-2010) Macs too old for anything newer.

High Sierra's headline change happened almost invisibly to most users: it migrated Macs from the decades-old HFS+ filesystem to APFS, Apple's modern copy-on-write filesystem, in the background during upgrade. It remains the newest MacOS many 2009-2010 Macs can run at all. Apple has hidden its Mac App Store listing from search, but the direct link to that same listing still works -- a real, if less discoverable, official download path.
