macOS High Sierra is a great update and brings lots of new and much needed improvements but that doesn’t mean that some of the changes can’t be annoying.
For example, just like in macOS Sierra, one of the changes that Gatekeeper comes with is that there’s no immediate way to allow unsigned apps to open.

1. Open up Terminal, type “sudo spctl –master-disable”( no quotes ), and hit enter ( NOTE: you might not be able to copy – paste the command in the terminal. See the screenshot below to make sure you enter it correctly )
2. Type in your password ( you won’t be able to see what you’re typing ), and hit enter
3. You’re done.
