Vain RoweOn MacOS Ventura 13.4, I always get the error "Not authorized to send Apple events to System Events. (-1743)." Normally, I would expect a prompt to appear the first time the action is run asking me to give permission, but that never happens. I also do not see any place in Security/Privacy settings (e.g. under Automation) where I can allow this action. I've also tried running the compiled app from the terminal command line (i.e. "open fullscreen.app") and I get the same error there, with no option to give permission. I've tried adding the app under Privacy/Security-->Accessibility, but it makes no difference. How can I get around the 1743 error?
Tons of Mac users have complained about the "Not authorized to send Apple events to System Events. (-1743)" error code when launching an app on Mac. This is super weird and annoying especially when you're burning on some business on the Mac workstation.
Don't panic, however. Every error code or notification indicates that something is going wrong and most of them can be resolved with pertinent solutions. This "Not authorized to send Apple events to System Events. (-1743)" error message is not an exception, either. Just follow this post from iBoysoft to terminate this prompt for a successful app launch.
Not authorized to send Apple events to System Events, how to fix it:
Although causing trouble by interrupting the normal launch of any app on Mac, it's not challenging to fix the "Not authorized to send Apple events to System Events" issue at all. You can follow the tutorial below to open the system settings to disable this notification with ease:
- Launch the app to trigger the block message saying "Not authorized to send Apple events to System Events. Not authorized to send Apple events to System Events. (-1743)" on your Mac.
- Click the Apple menu on the upper left corner of the Mac desktop to choose System Settings from the dropdown menu.
- Scroll down to find the Privacy & Security tab in the left menu bar.
- Navigate the Automation tab on the right menu bar.
- Search for the app name that triggered the notification before.
- Toggle the switch of "System Events" to On.
- Launch the app one more time and see if it opens normally.
These steps are suitable for users who run macOS Ventura and later operating systems. If you're running macOS Monterey and earlier macOS, please do the following:

- Go to System Preferences from the pulldown menu and select Security & Privacy.
- Go to the Privacy section to select Automation, and then click on the Privacy tab.
- Check the box for "System Events" to open the app successfully later.
With the System Events being opened, now you can try to launch the app to see if it opens properly. If not, consider reinstalling the problematic app or reinstalling macOS.

Tips you should bear in mind when fixing the 1743 error
Toggling on the System Events helps fix the error message, though, it's risky when you give an unsafe and insecure app such permission. An untrusted app has the potential to steal your info, plant viruses, malware, adware, or spyware on your Mac hard drive overriding your permission.
Therefore, check whether the app is secure before you open the System Events setting. You can tell if an app is secure by tracing its download source, for instance, the app is secure and trusted when being downloaded from the App Store or the website/developer identified by Apple. Or, the app never recommends associated software or extensions for you to install.
Anyway, paying more attention to your info and data will never be improper in nowadays where the info leak is no crazy!
