What's Coming Next
macOS 27.2 is out and macOS 27.3 is in beta:
- macOS 27.2 — released October 26, 2026 (build 26B123); Apple skipped 27.1
- macOS 27.3 — beta 1 (26C5035r) seeded November 3; Safari vertical tabs, Markdown in Quick Look; release expected mid-December
- macOS Tahoe 26.7.2 — latest release for Intel Macs (October 26); security-only updates continue until about autumn 2028

- Sonoma 14 — end of support as of August 2026; final version 14.8.9
Understanding Build Numbers
Apple's build numbers follow a specific format that tells you about the version:
- First digits: Major macOS version (e.g., 26 = Golden Gate, 25 = Tahoe, 24 = Sequoia, 23 = Sonoma)
- Letter: Stage in development cycle (A–Z)
- Remaining digits: Build iteration within that stage
How to Check Your Mac's Update History
Your Mac keeps its own record of everything it has installed. To see it:
- Current version: Apple menu → About This Mac. Click the version number to reveal the build.
- Installed updates: System Settings → General → Software Update → the info button next to “Automatic Updates” history.
- Full install log: open Terminal and run
softwareupdate --historyfor a dated list of every update this Mac has applied. - Match it up: compare the build number you find against the table above to confirm exactly which release you are on.
How Often Apple Ships Updates
Reading the history above, a clear rhythm shows up:
- One major release a year, announced at WWDC in June and shipped in September or October.
- Point updates roughly every 6–8 weeks (27.2, 27.3…), each adding features and fixes. Numbers are occasionally skipped: there was no macOS 27.1.
- Rapid Security Responses and x.y.z patches land in between, sometimes within days of an actively exploited flaw.
- Two older releases stay supported with security-only updates, so Tahoe 26 and Sequoia 15 still receive patches alongside macOS 27.
