I AM now running El Capitan 10.11. I was faked out before in that I received the Apple invitation to try the Beta. I thought I checked the right boxes since I immediately got about 15 or more updates that even they all thought said Yosemite. Figured that was strange but 15 updates out of the blue???
I went back to the invitation and apparently clicked on the right box this time and El Capitan downloaded in one big file. Another thing that made me think I was using the beta was some of my OEM programs stopped running until I go into one of the last new Yosemite updates. One program was 1Password that finally started working again. Running with 10.11, 1Password seems fine now.
