Prerequisites

Installing the CrowdStrike Falcon Sensor requires elevated privileges. To see supported versions of MacOS see the CrowdStrike FAQs

Browser Dependencies

CrowdStrike currently supports the Google Chrome browser for use with the Falcon UI. We support the current release of Chrome as well as the prior two major versions. Other browsers may work, but we do not support other browsers at this time.

Installing the Falcon Sensor for Mac

  1. Download the sensor installer from Hosts > Sensor Downloads. Use the Chrome browser.
    • CrowdStrike currently supports the Google Chrome browser for use with the Falcon UI. We support the current release of Chrome as well as the prior two major versions. Other browsers may work, but we do not support other browsers at this time
  2. Copy your Customer ID Checksum (CID) from Hosts > Sensor Downloads.
    • CID Location in Host App
  3. Run the sensor installer on your device in one of these ways:
    • Double-click the .pkg file.
    • Run this command at a terminal, replacing <installer .pkg> with the path and file name of your installer package.sudo installer -verboseR -package <installer .pkg> -target /
  4. When prompted, enter administrative credentials for the installer.
    • Note: macOS 10.13 High Sierra: When you install the Falcon sensor, follow the OS prompts to approve installation of a kernel extension. This authorization is not required when installing via a desktop management tool, such as JAMF.
  5. Run falconctl, installed with the Falcon sensor, to provide your customer ID checksum (CID).
    • This command is slightly different if you’re installing with password protection (see documentation).
    • In this example, replace 0123456789ABCDEFGHIJKLMNOPQRSTUV-WX with your CID.

    sudo /Library/CS/falconctl license 0123456789ABCDEFGHIJKLMNOPQRSTUV-WX

After installation, the sensor runs silently. To confirm that the sensor is running, run this command at a terminal:

sysctl cs

The output shows a list of details about the sensor, including its agent ID (AID), version, customer ID, and more.
