To upgrade to Mojave on my imac, I was asked to add a helper as an administrator to my computer. Why, and is this legitimate?
I have a less than 1 yr old imac Retina 5K, 27", 2017, running OS 10.13.6. I am the administrator. When I attempted to install Mojave, I received a message that I need to install a helper. I am suspicious. What is this helper, and why do I need to install it when I am already logged in as administrator? Finally, Is this legitimate, or is my computer infected with some form of malware that is trying to gain access?
iMac with Retina 5K display, OS 10.13.6
