Question: Apple USB Mouse in OS 10.11.6
I have an Apple USB mouse. OS 10.11.6 I want to have both left and right clicks as primary. I have set this in system preferences but it still wont work. If I change the left to be secondary and the right to be primary, this doesn't work either. The Mouse is only new and I have tested it on OS10.6.8 and it works fine. Other operations such as trackball and side buttons can be changed and the changes applied. Any suggestions?
