I need to set up my devices (again) to receive texts messages on multiple devices.
When I had one-to-one support, the Apple employee helped to set this up after my desktop hijacked my messages preventing messages making to my iPhone. Now, they arrive on my iPhone, but not my iPad or iMac. Something has 'flipped a switch' somewhere. I need to know where the 'switches' are to set them properly.
iMac, OS X Yosemite (10.10), iPad & iPhone 6 & MacBook.....
