macOS timeline

Every release we support, against every version of macOS. Find the column for the macOS you run, then look down it — if a row is filled under your macOS, that release runs on your Mac.

Why 27 has two columns. The Beta 5 column is a measurement: we ran these releases on the Golden Gate Beta 5 pre-release in August 2026, and everything that runs on Tahoe ran there — so it carries full marks. The second 27 column is Golden Gate as it will ship, and that stays “expected” until it does: a beta test is real, a support statement waits for the shipped version. macOS 28 shows “expected” where nothing we know of stops a current release, and a dash everywhere else — including for the Rosetta 2 rows, where the reason is sourced: Apple removes Rosetta 2 there.
Note 1 — v12 (build 1204.98). This build exists for Macs that cannot update to macOS 12 Monterey or later. If your Mac runs macOS 12 or later there is no reason to run it — the current build, v12 (build 1204.219), is the one to install. That is why its marks turn grey from macOS 12 on.
Note 2 — Heritage Edition. Only for customers who specifically paid for a long-term Heritage Edition subscription prior to October 31st, 2024 — that window is closed, and it cannot be supplied to anyone else. Unlike build 1204.98 it has a reason to stay in use on every macOS it runs on: it is the only build that still has PhotoRender and Animation, and the only one with Parasolid export. That is the picture as of build 1204.219 — however, all of them are being worked on, and we are on target to have the functionality replaced prior to October 31st, 2026.

Windows timeline

The same picture for Windows. Microsoft's own end of support is shown under each version — a machine past it still runs the software, but no longer gets Windows updates.

Supported on that Windows version — runs natively
Note 1 — v12 (build 1204.98). On Windows this build exists so the Mac 1204.98 has a same-number Windows partner for divergence testing — it was never the build a Windows customer should run. There is no Windows reason to be on it: the current build, v12 (build 1204.219), is the one to install.
Note 2 — Heritage Edition. Only for customers who specifically paid for a long-term Heritage Edition subscription prior to October 31st, 2024 — that window is closed, and it cannot be supplied to anyone else. On Windows as on the Mac it is the only build that still has PhotoRender and Animation, and the only one with Parasolid export — the reason holders keep running it. That is the picture as of build 1204.219 — however, all of them are being worked on, and we are on target to have the functionality replaced prior to October 31st, 2026.

A dash does not mean broken — it means we do not support that combination. For your specific Mac, the compatibility checker gives a direct answer.
