* Onboard your instance to use ITOM Cloud Services. For details, contact Customer Support.
* Configure an agent registration key.
* Role required: root
{#install-acc-for-dex-macos__prereq-ul-acc-install-macos}

## Procedure

1. Retrieve the agent registration key:

   2. Select the relevant agent registration key.
   3. Copy the registration key value and store it in a place where you can easily retrieve it when needed.

2. Retrieve the publicly accessible gateway URL, based on your location:  
   * AMER (Americas): `itomcnc-prod-gateway.amer.sncapps.service-now.com:443`
   * EMEA (Europe): `itomcnc-prod-gateway.emea.sncapps.service-now.com:443`
   * APAC (Asia Pacific): `itomcnc-prod-gateway.apac.sncapps.service-now.com:443`
   {#install-acc-for-dex-macos__ul_cjk_gnz_xxb}
3. On the server where you're installing the Agent Client Collector, enter the following command:  

       CONNECT_WITHOUT_MID="true" ACC_CNC="<gateway_endpoint>" REGISTRATION_KEY="<registration_key>" INSTANCE_URL="https://<instance_url>" bash -c "$(curl -L https://<instance_url>/api/sn_agent/agents/install_agent)"

   The following table describes the parameter values in the command.
   {#install-acc-for-dex-macos__table_i4m_yjq_wxb__entry__2}

   | Parameter | Value |
   |-|-|
   | CONNECT_WITHOUT_MID | Specify true to enable MID-less installation. If you don't specify a value, the regular MID Server websocket installation is invoked. |
   | ACC_CNC | Public gateway endpoint for Agent Client Collector that you can specify. |
   | REGISTRATION_KEY | Active and valid agent registration key for the agent to communicate with. |
   | INSTANCE_URL | ServiceNow instance that the agent is registering with. |
   | ACC_ALLOW_LIST | Optional ACC_ALLOW_LIST=0 string that you can add to disable the allow list. Default: The allow list is enabled. Note: When you disable the allow list, you compromise your system's security. This action is intended as a temporary measure while you're updating the allow list. After you complete the update, remove ACC_ALLOW_LIST=0 from the command line. |
   | ACC_VALIDATE_SIG | Optional ACC_VALIDATE_SIG=0 string that you can add to disable the verification of the installer certification validation. Default: Validation is enabled. Note: Disable the certification validation only when you're using non-standard signature validation tools. |
