Michael- Updating SS from 26b1 to 27, but after running the installer, checking for updates reports again that 26b1 is installed not 27; and of course Mail disables it. I ran the installer twice, and restarted between. no joy, installer in the same unproductive loop.
This is on one machine only. Another machine no problems updating. Tried running the Terminal commands but reports that the item is already there ( if memory serves).
Of course it’s my wife’s machine giving me trouble.
