I rebooted my Intel MacBook Pro, this morning, and I suddenly was confronted with MacOS Sonoma vineyards wallpaper.!!! Then, I checked About ths Macintosh, which confirmed that I was running macOS Sonoma! I HAD NEVER INTENDED THIS!!!!
I did get prompted last night to install iOS 17.0.2 and iPad OS 17.0.2, which I did. When, my macOS Ventura 13.6 wasn't upgraded to Safari 17 for a couple of hours, I used Dr. Howard Oakley's Silent Knight to install it, which was successful.
I had read warnings about accidental upgrades to Sonoma, and to read carefully before doing updates. Not sure what happened, yet.
I have multiple Time Machine and Carbon Copy Cloner backups, and had made a macOS Ventura 13.6 bootable installer on a USB thumb drive. So, if I have to, I guess I could revert back to Ventura.
But, for now, I will test macOS Sonoma, and if there are no serious problems, I'll stay on it.
