Install the Cortex XDR Agent for Mac
Before installing the Cortex XDR agent on a Mac endpoint, verify that the system meets the requirements described in Cortex XDR for Mac Requirements.
Install the agent using a software distribution tool of your choice (such as JAMF) or using the following workflow:
- Download the installation package you want to install from Cortex XDR.
- Copy the installation package to the endpoint on which you want to install the Cortex XDR agent software.
- Unzip the installation package.
- (Optional) Configure a Cortex XDR agent specific proxy on the endpoint.If you are deploying Cortex XDR in an environment where the agents communicate with Cortex XDR through a proxy, you must assign the proxy IP address and port number during the agent installation on the endpoint.
- Locate theConfig.xmlfile in the unzipped installation folder.
- Edit the<proxy_list>tag.<proxyserver>:<port></proxy_list>
- To install an agent with a Cortex XDR specific proxy, enter your proxy IP address and port number. You can assign up to five different IP addresses per agent, and the proxy for communication is selected randomly with equal probability.<proxy_list>10.196.20.244:8080,10.196.20.245:8080</proxy_list>
- After the initial installation, you can change the proxy settings in Cortex XDR.
- Install the Cortex XDR agent software.
The Cortex XDR agent logs any installation errors to/var/logs/installation.log. If installation fails for any reason, you can view this log to better understand the cause of the installation failure.
- Run theCortex xdr.pkginstallation file.
- ClickContinueto proceed with the installation.
- If prompted to confirm the destination, clickContinue.
- ClickInstallto begin the installation.
- Enter theUser NameandPasswordof the administrator with access to install software on the endpoint, and then clickInstall Software.
- (macOS 10.13 and later versions) Allow Cortex XDR to install system extensions:
- Dismiss theSystem Extension Blockedwarning.
- Go toand selectSystem PreferencesSecurity & PrivacyGeneralAllow.
- After the installation completes, verify your connection.
- To open the Cortex XDR agent console, click the agent icon in the menu bar, and selectOpen Console.
- ClickCheck In Nowto initiate a connection with your tenant of Cortex XDR. If successful, theLast Check-Infield updates to display the recent check-in date and time.If the Cortex XDR agent does not connect to Cortex XDR, verify your internet connection and perform a check-in on the endpoint. If the agent still does not connect, verify the installation package has not been removed from the Cortex XDR management console.
- (macOS 10.15 and later versions) Grant full disk access.Due to changes in the security settings of macOS 10.15, you must allow the Cortex XDR agent full disk access on your endpoint to enable full protection. If you do not authorize the agent full disk access on your endpoint, the agent provides only partial protection of files in the/Applicationsdirectory. The first time the agent detects an attempt to run an executable file located in another protected location on the endpoint as part of the anti-malware flow, macOS will deny the Cortex XDR agent access and prompts the user to grant full disk access.You can grant the Cortex XDR agent full disk access manually or using a third-party tool such as JAMF.To grant the Cortex XDR agent full disk access locally on the endpoint:
- Go totab, and selectSystem PreferencesSecurity & PrivacyFull Disk Access.
- To make changes, click lock icon ( ) on the bottom left, enter your credentials, andUnlock.
- Navigate to.Macintosh HDLibraryApplication SupportPaloAltoNetworksTrapsbin
- Selecttrapsd,authorized, andpmd.
- When you’re done, click to save your changes and stop editing.
