Apple today provided the second beta of an upcoming macOS Tahoe 26.5 update to developers for testing purposes, with the update coming two weeks after the first beta.
Developers can download the macOS Tahoe 26.5 update by opening up the System Settings app, selecting the General category, and then choosing Software Update. Beta Updates will need to be enabled, and a free developer account is required.
No new features were found in the first macOS Tahoe 26.5 beta, and it's likely the update primarily focuses on bug fixes and performance improvements.
