Has anyone tried getting this latest MacOS Sequoia beta installed on an external SSD and then trying out by booting from the SSD instead of the internal hard drive of a MacBook Pro? This would allow users to test out the Sequoia and Apple Intelligence features without committing to a beta release until it's fully released and found stable and as bug-free as possible.

If so, any tips or links for how to do so?
