Overview
- Reporters and sleuths discovered a hashflag image filename on X that includes the string “Project_Big_Bear,” which has prompted early speculation that macOS 27 could be called macOS Big Bear.
- The filename discovery was publicly noted on Tuesday, June 2, 2026, by multiple outlets and contributors who showed how to view the hashflag image URL that contains the Project_Big_Bear label.
- Apple has not confirmed any macOS 27 name and outlets caution the filename could be unrelated or accidental, so the finding should be treated as unconfirmed until Apple speaks at WWDC.
- Prior reporting frames macOS 27 as a refinement of macOS Tahoe focused on bug fixes, stability work, and Apple Intelligence upgrades such as a new Siri app, which helps explain why names tied to Lake Tahoe area features have been suggested.
- Apple has a history of filing California-themed trademarks and later using place names for macOS releases, so a verified Big Bear name would continue a long-standing naming pattern and shape expectations for the WWDC reveal on June 8.
