I cannot connect to "help" in any app.
I have been a Windows user since way back. I have recently changed to mac and am in the process if setting up my imac retina display. I was relying on the "help" function of the apps to familiarize myself with Mac. When I select a topic in any of the help menus, I get the message
"The selected topic is currently unavailable
Make sure you’re connected to the Internet. For help connecting, choose Apple menu > System Preferences, click Network, and click “Assist me.”
If you’re connected to the Internet, and the content still doesn’t appear, try again later."
I am connected to the internet via ethernet to Airport Extreme, my browser works fine. My sons' mac laptop has the same problem on my internet service but not on his. I am on NBN Satellite. Has anyone else had this problem and what was the solution?
iMac with Retina 5K display, OS X Yosemite (10.10.4)
