Filename Suggests 'Big Bear' Could Be macOS 27

An apparent internal label points to Apple following its California-place naming pattern and could be confirmed at the WWDC keynote on June 8.

Overview

  • A hashflag image file for Apple’s WWDC hashtag was found to include the string "Project_Big_Bear_2026," a detail first reported by multiple outlets after the discovery on Tuesday, June 2.
  • Designers and code sleuths including Andreas Storm and Aaron Perris located the filename by copying the small Apple logo image URL for the #WWDC26 hashmoji and inspecting the address text.
  • Outlets stress the finding is unconfirmed because internal filenames can be provisional, symbolic, or deliberate misdirection and Apple has not announced macOS 27’s official name.
  • Separate preliminary reporting says macOS 27 will mainly polish macOS Tahoe with bug fixes and stability work while adding a new Siri app and Apple Intelligence enhancements, though those feature reports remain tentative.
  • Apple’s long habit of using California place names and past trademark filings make Big Bear a plausible choice but the WWDC keynote on June 8 is the decisive moment when Apple will confirm the name and features.
