So i installed MacOS Sierra on my retina iMac, I have an iPad pro and an iPhone 5s too, all on the same Apple account, same wifi network and bluetooth switched on on all three. I can see the iPad pro and iPhone in the Bluetooth preferences of the iMac, they have been paired but they show not connected. I have upgraded to Mac)S Sierra, the iPhone and iPad both have IOS 10 on them. I have tried to use the Universal clipboard but nothing happens at all when trying to copy from the IOS devices to the iMac, and on one occasion I managed to get the progress circle when copying from the Mac to the iPad, but nothing actually got copied. I'm highlighting text or images on both and trying to copy to the other. So, what am I doing wrong? There doesn't appear to be any settings to tick or allow. I noticed when upgrading to MacOS Sierra that i had to change the password for the include on the Mac, but I have not been asked to do the same for either of the IOS devices. Photostream is still working (take a picture on one IOS device it appears on the Mac and the other IOS device), as is phone handoff and messages. Any suggestions to get this clipboard working please?
