Safari Release Notes | Apple Developer Documentation


I don't know why you think that Safari 27.0 is older than Safari 18.6.

  • Safari 18.6, released on July 29, 2025, supported Ventura, Sonoma, and Sequoia.
  • Safari 27.0, released on September 14, 2026, supports Sequoia, Tahoe, and Golden Gate.


Safari 27.0 is two major versions newer than and over a year newer than Safari 18.6. If you are running Sequoia, and are still running Safari 18.6 (having never updated to Safari 26.* or Safari 27.0), Safari 27.0 is by far the newer browser. Even if you're staying on Sequoia (in your case, because you have an Intel-based MacBook Air that can't go further; in my case, because I haven't felt a need to upgrade to Tahoe or Golden Gate yet).
