I am having a 2013 macbook pro 13inch. with Yosemite 10.10.5, I have an issue with the facetime function. I cannot receive calls from the facetime, and sometime I cannot even call out. The only time I can dial out, is both of us are calling to each another. How can I fix this?
MacBook
Pro, OS X Yosemite (10.10.5)
