Apple today released the second beta of an upcoming macOS High Sierra 10.13.6 update to public beta testers, two weeks after releasing the first public beta and a day after releasing the second beta for developers.

Beta testers who have signed up for Apple's beta testing program will be able to download the new macOS High Sierra beta through the Software Update mechanism in the Mac App Store.

Those who want to be a part of Apple's beta testing program can sign up to participate through the beta testing website, which gives users access to iOS, macOS, and tvOS betas.

No notable features or changes were discovered in the first two betas of macOS 10.13.6 provided to developers, suggesting the new software focuses on bug fixes and other under-the-hood updates.

macOS 10.13.6 is likely to be one of the last updates to macOS High Sierra, as Apple is transitioning to macOS Mojave. macOS Mojave was unveiled last week at the Worldwide Developers Conference.

The #1 thing I and a lot of users want to see is support for legacy software. Specifically in my case of Adobe Illustrator and Photoshop CS4. Just because Apple is changing the work bench every year doesn't mean I want to be buying all my tools over again. I would love to see Apple offer support for all software all the way back to the original Mac. They have the skills, the knowledge and the money, great gobs of money, as well as the computing power to do emulation of everything. There is a tremendous amount of wonderful legacy software, especially in the educational field that has never been recreated for the new OSs.
