The only reason we already have a 15.1 beta is Apple Intelligence. As this requires an Apple Silicon equipped Mac it wouldn’t make any sense to release a 15.1 beta for Intel. Once there are legit updates other when Apple Intelligence, like bug fixes and security patches any Mac supporting macOS Sequoia will get those subsequent dot updates as well.Okay...wondered why include 2018 MBP then, if it stops at 15.0...sometimes Apple makes nonsense, indeed.
