Hello everyone,

After spending hours digging through forums trying to find a reliable way to fully automate the AVID NEXIS Client Manager installation on macOS, I’m sharing this step-by-step guide to save others the same trouble I went through.
Unfortunately, Avid doesn't provide much help on this topic, so I hope this helps streamline your deployment.
I’m aware that this isn’t the most secure or ideal approach, and there’s definitely room for improvement — but it works for us.
If you have suggestions or improvements, feel free to share!
If this can help new Mac admins or anyone else, all the better!

Useful resources I consulted:

• Managing Legacy Kernel Extensions in macOS Using Jamf Pro - Technical Articles | Jamf


• System extensions in macOS - Apple Support (CA)

System Security Prerequisites

Before any installation, it's critical to adjust macOS security settings to allow the required kernel extensions for AVID NEXIS to load properly.

For Apple Silicon Macs (M1/M2/M3):
Boot into recovery mode, open the Startup Security Utility, and:

• Set security to "Reduced Security"


• Check "Allow user management of kernel extensions from identified developers"

For Intel Macs:
Boot into recovery mode and run the following command in Terminal to disable SIP:

csrutil disable

These steps are required to enable the system to load the necessary kernel extensions.

PPPC Configuration

App Identifier to allow:

• Bundle ID: com.avid.AvidNEXISClientManager

Code requirement:

anchor apple generic and identifier "com.avid.AvidNEXISClientManager" and

(certificate leafifield.1.2.840.113635.100.6.1.9] /* exists */ or

 certificate 1tfield.1.2.840.113635.100.6.2.6] /* exists */ and

 certificate leafifield.1.2.840.113635.100.6.1.13] /* exists */ and

 certificate leafisubject.OU] = "4UYUA773XD")

Services That Can Be Preapproved (No User Interaction Needed)

You can preauthorize the following services via a configuration profile to avoid user prompts during AVID NEXIS usage.
Choose what’s relevant for your environment:

• SystemPolicyNetworkVolumes


• FileProviderPresence


• SystemPolicyDocumentsFolder


• MediaLibrary


• SystemPolicyDesktopFolder


• SystemPolicyRemovableVolumes


• SystemPolicyDownloadsFolder


• Accessibility


• SystemPolicyAllFiles

KEXT: Kernel Extension Approval

Information required for your configuration profile:

• Developer Name: Avid Technology Inc


• Team ID: 4UYUA773XD

Kernel extensions to approve:

(Optional: Only approve specific bundles as needed.)

Deployment Steps

1. Deploy the AVID NEXIS client installer PKG using Jamf or your preferred tool.


2. Run a license/configuration copy script, if required.


3. Reboot the machine with kext cache rebuild (no delay).
