Information Technology

macOS is the operating system Apple has developed and marketed for its Mac computers since 2001, built on a proprietary Unix foundation derived from OPENSTEP and FreeBSD. It remains the second most widely used desktop operating system worldwide, behind Microsoft Windows and ahead of the various Linux distributions. The most recent version, as of 2026, is macOS 26 Tahoe, the operating system's twenty second major release.

In Sector

Entity identity for the business product-service.sector GICS enum value this member already carries, per the phase 3 entity-backed browse bucket pilot (docs\design_entity_backed_browse_buckets_20260928.md, owner decision 2026-09-28 on business product-service.sector, w-bucketpilot-gics-0929). The sector fact itself, with its own citation, remains on the member entity unchanged; this edge only adds the durable entity identity the enum value already names.
