So you are saying that I and other consumers are unwise to download and attempt to use 'updates' that are not listed as 'Beta' or test updates? When 'updates' are promoted as 'final' and complete software 'versions', one should expect them to be fully functional. Perhaps with a necessary 'fix' to new features, but features present in older versions should be expected to carry forward their functionality.
The least Apple should do is make the older version- of something as all encompassing at the Operating System- available as a retrograde. But it isn't. Once you commit to the new OS, you are stuck being Apple's guinea pig to do beta testing until they see fit to fix it.
