I always run my systems under an Admin \ Standard user dichotomy. In other words, I always use my system as a Standard user and never login to the Admin user (except when doing the initial clean install and configuration).
This seems to mostly work on macOS (except for this previously noted annoyance).
However, I specifically have an irritating problem with Skype, where it will pop up a authentication Window stating:
An update is ready to install. Skype is trying to add a new helper tool.
...and asking for my Administrator account credentials.
Now, I've had other programs ask for similar authentications for updates and installs from time to time, and I simply put in my credentials and it installs some update quickly and I continue about my business. No problem.
However, with Skype, it seems something is simply not working - like perhaps it wasn't designed with Standard users in mind.
After entering my Administrator credentials - nothing installs. The authentication window simply disappears and nothing happens.
But even worse... the window will inevitably appear again after an hour or two. So I'm constantly being harassed with this notification, and no matter how many times I authenticate the request (dozens of times so far), it just keeps coming back.
Note that I had this same problem back in Yosemite running whatever version of Skype was the latest back then. I recently did a clean install of High Sierra, and I had hoped this problem would disappear.
Nope. Any ideas?
