I’m going to advise you that (unofficially) it’s time to begin moving off macOS 10.11 and Windows 7.
A good number of support issues can be solved by simply updating your OS.
I know there is reluctance to move off these versions of the OS (especially you WIN 7 hardcores), so I do understand. These versions of the OS are still supported, however, you may encounter unexpected behavior if you continue to use them.
It may be time to “have that talk” with the IT guy if you are in an enterprise environment.
Let me know if you have questions.
