I might not install macOS 26. It's too big a leap from macOS 15.

These updates mostly provide SDK-compatibility with the next OS releases, so developers can more easily target the previous major OS release without compromising functionality for the current (next) major OS release.

apple accidentally also released macOS 26.0 beta 4 (25A5316i) but this has since been pulled


not sure if re-release will have same build

this also manifested as some sort of accidental tahoe public beta: https://www.macrumors.com/2025/07/21/macos-tahoe-public-beta-accidental-release/ which has also been pulled

one has to wonder how such a monumental mistake can happen
