I use teamviewer almost a decade. Remote connection & desktop with no problems! It was the program which succeed to connect, when all others failed. But no more in my case! El capitan 10.11.2 and teamviewer 11. Impossible to connect anywhere. I try to connect from mac, to several pcs. The target computer-pc seems to receive the 'signal' from mac, as I observed in the pc side by side with my mac, but it does not connect. Connection failure. Am I the only one with this awful problem? Is this an incompatibility? Any solution?
