iTunes now fine
For months, whether before and after updates, I would have to sign off the remote speakers in iTunes than reboot them. I kept thinking the next update would fix the problem. Annoying but I lived with it. As of yesterday they connect fine. I always wait till the computer is finished starting up, then start the the wifi and then iTunes. i have done nothing different nor have there been any recent updates. Nor did I run Disk Utility. Happy but I don't like the mystery!
