How to Install Software from 'Anywhere' on macOS High Sierra


It's been a while since I was focused on being a practicing macOS admin. I just ran across a wrinkle in macOS security that I'd forgotten. I catalog it below for your use and to burn it into my memory.

As I was installing a new endpoint security package on an Mac for testing, I noticed that the file failed to launch and failed to funtion when launched manually.

In my research, I found and followed the current vendor's KB on this issue which instructed me to click "ok" on the package error dialog to be taken to > Security, where I could click Allow and be on my way.

Guess what no longer appears in


Nowhere. Nothing.

And...clicking the lock, authenticatng and selcting Anywhere as an allowed devloper doesn't work, either. Anywere isn't an available selection.

Then, lightning struck.

Didn't this change with OS X Sierra (10.12)?


A Forked Path

To allow "Anywhere" as an approved software developer in HighSierra, there's only a bash command:

$ sudo spctl --master-disable

Then, the process forks....

For mass deployment, or use by the console-loving (I'm writing this in Vim), use

sudo installer -pkg /Path/to/pkg -target /

This launches the package, bypassing the user access control, and allows the package to install and run. Without bypassing UAC, it will install, but not run...or run completely..

Feeling Right-Clicky?

For single deployment, one can right-click (opt-click) on the package.pkg and select Open from the context menu. This will prompt for uac authentication.

On successful authentication, the package is installed with privileges to launch.

Afterward, the package starts and runs normatively.

Button Up!

The corollary of the command above is....

$ sudo spctl --master-enable

On restart, returning spctl to it's OOBE state seems to allow the application to launch and function.

If you want to ensure that state,

$ sudo spctl --add _Path/To/Application.app_

This adds the application to the control whitelist.

In my case, the command was

$ spctl --add /Applications/

I installed it by passing the -target / flag to installer on the command line.
