Common Causes

macOS includes several security features, such as System Integrity Protection (SIP) and Gatekeeper, that help keep your Mac secure. Occasionally, these features may prevent approved business software from installing or running correctly. This guide explains how to check security settings and safely allow trusted business applications without disabling essential system protections.

Quick Fix Steps

Check your macOS version and ensure the software is compatible.
Review Privacy & Security settings for any blocked applications or system extensions.
Use Gatekeeper options to open apps from identified developers.
Contact your software vendor for macOS-specific installation instructions.

Detailed Instructions

Check Your macOS Version

Click the Apple menu () in the top-left corner of your screen.
Select System Settings.
Click General in the sidebar, then click About.
Note your macOS version and compare it with the software vendor's system requirements.

Review Privacy & Security Settings

Click the Apple menu () and select System Settings.
Click Privacy & Security in the sidebar.
Scroll to the Security section.
If a message indicates an app was blocked, click Open Anyway next to the application name.
Enter your administrator password when prompted.
Check sections such as Full Disk Access, Screen Recording, and Accessibility if the software requires specific permissions. Enable these only if required by the software vendor.

If you see a message about a blocked system extension, you may need to approve it in Privacy & Security settings and restart your Mac.

Open an App Blocked by Gatekeeper

Go to System Settings > Privacy & Security.
Scroll to the Security section.
If a message indicates the app was blocked because it is from an unidentified developer, click Open Anyway.
Enter your administrator password when prompted.
The app will now open and be added to your security exceptions.

Allow System Extensions (If Required by Vendor)

Go to System Settings > Privacy & Security.
Look for a notification about a blocked system extension near the top of the window.
Click Allow next to the extension from your software vendor.
Restart your Mac when prompted.

Troubleshooting

Installation Still Fails

Verify the software is compatible with your version of macOS by checking System Settings > General > About.
Ensure you are logged in as an administrator account on the Mac.
Download a fresh copy of the installer from the vendor's official website to rule out a corrupted file.
Check the vendor's documentation for any known macOS compatibility issues or specific installation steps.

Gatekeeper Continues to Block the Application

Confirm the software is from a trusted source and the developer is identified with Apple.
Right-click (or Control-click) the app in the Finder, select Open, then click Open in the dialog box.
If the app still will not open, contact the software vendor for an updated, notarised version compatible with your macOS version.

System Integrity Protection (SIP) is a critical security feature. Do not disable SIP unless explicitly instructed by your software vendor and approved by your organisation's IT administrator. Disabling SIP increases your Mac's vulnerability to malware and unauthorised system changes.

If you are unsure whether your business software requires security setting changes, check the vendor's documentation or contact 220 Internet Services before proceeding.
