Before you can use N-able N-central to monitor and manage computers at a customer's site, you need to install the agent. The Mac agent monitors local services and reports any issues.
There are customer-specific and generic system installers.
The customer-specific installers are pre-configured with activation keys, registration token, customer names, and IP address of your N-able N-central server. As the customer-specific installers are very easy to use, we recommend that you make them your first choice when downloading the agent or probe software.
Generic system installers require you to specify either the activation key, or the IP address of your N-able N-central server and a customer name or customer ID. These installers are useful when you want to keep a copy of a certain version of the agent or probe offline.
You need a universal administrative account on every OS X device to facilitate agent installation. It is recommended that you create at minimum one account for your workstations and a separate account for servers.
To install the agent silently on a Mac OS device, see Perform a Mac agent silent install.
For troubleshooting installation issues, see the N-able MSP Success Center Knowledge Base.
The MacOS agent supports the following operating systems:
Mac Agents
- 10.15 (Catalina)
- 10.14 (Mojave)
- 10.13 (High Sierra)
- 10.12 (Sierra)
You need a device's agent activation key to install the agent software. Activation keys are located on the All Devices view. To copy the agent activation key, hover your mouse over the key icon and copy.
- Click Actions > Download Agent/Probe.
- From the Select Customer/Site drop-down menu, select a customer or site.
- Click Get Registration Token.
When selecting a customer-specific agent to download, the registration token is included in the download. You do not need to generate a key. For more information on registration tokens, see Registration tokens for agent installation.
- In the System Agent/Probe area, click the MacOS Agent link and select a location to download the DMG file.
- Once the install file has downloaded, navigate to the downloaded file location.
- Double-click the DMG file and follow the instructions on the Installer screen.
If you are installing the agent from the customer/site level, the installation proceeds. At the System level, you must enter either the activation key or customer name and ID, also known as an Access Code, which can be found by clicking Administration > Customer/Sites.
Install the MAC agent with the dmg-install.sh script
- From N-central download the 'DMG Installation Script' and the 'macOS Agent (dmg)'.
- Make sure to extract the script into the same folder location as the dmg.
- Use one of the methods below to install:
- With an activation key, retrieved from the central server:
sudo dmg-install.sh -k <activation key>
- Prior to N-central 2020.1, with a Customer Name and Customer ID (Customer name may need to be quoted if it contains spaces or shell meta-characters):
sudo sh dmg-install.sh -s <server endpoint ip/fqdn without the https://> -c <customer name> -i <customer id>
- On 2020.1 or later with a Customer Name and Customer ID (Customer name may need to be quoted if it contains spaces or shell meta-characters):
sudo sh dmg-install.sh -s <server endpoint ip/fqdn without the https://> -c <customer name> -i <customer id> -t <registration token>
- With an activation key, retrieved from the central server:
- Additional Flags:
- -p Specify the protocol for the agent to use.
- -a Specify the port for the agent to use.
- -x Specify an http proxy for the agent to use.
- Once the script has run navigate to All Devices and click the Network Devices tab.
- Click Add.
- Click Discovered Assets.
- Select your device and import it.
Your device should now be added in N-central.
You can confirm this from the Customer level, by navigating to All Devices, and click the Network Devices tab.
Install the MAC agent on Catalina
With Catalina, the Apple gatekeeper requires notarization during installation. The Mac agent installer is signed, but not notarized. When installing the Customer or System DMG installer it can fail to register. To complete the agent installation, you will need to open the System Preferences and select the Security and Privacy option to allow the agent to install.
Keep the System Preferences open for the duration of the install procedure.
- Click Actions > Download Agent/Probe.
- From the Select Customer/Site drop-down menu, select a customer or site.
In the System Agent/Probe area, click the MacOS Agent link.
- Navigate to the downloaded file location and double-click the DMG file.
- Double-click Register the N-central Agent and click OK.
- Open the Security and Privacy system settings options and unlock the settings with the admin password.
- In the Register the N-central Agent dialog, click Open.
- Click Register and enter the user password and click OK.
- Click Cancel for the message saying the .Mac_Agent cannot be opened.
- In the Security and Privacy dialog, in the Allow apps downloaded from area, select App Store and identified developers and click Open Anyway.
- In the subsequent dialog, click Open.
- Enter the user password in the security prompt and click OK.
- This will result in the completion of the install.
PuTTYgen is a tool used for generating public and private SSH keys which are its fundamental function. Though it collects keys in its own file format i.e. .ppk files, keys can also be transformed to any other file format quickly. It is available for the various operating system, i.e. Windows, Linux, Mac, etc. PuTTYgen.exe is the graphical tool on Windows OS. While on the other side, Linux OS has the only command-line version.

PuTTYgen is used to generate public or private key pair for creating SSH keys. Below is the complete guidance about how to generate RSA key in Windows operating system:
- Once you install the PuTTY on your machine, you can easily run PuTTYgen. For the same, go to Windows -> Start Menu -> All Programs -> PuTTY -> PuTTYgen.
- You will see the PuTTY key generator dialog box on your screen
- You will find a “Generate” button in that dialog. Clicking on it will lead to generating the keys for you.
- Now you will need to add a unique key passphrase in the Key passphrase and Confirm passphrase field.
- Click on the “Save Public Key” and “Save Private Key” buttons to save your public and private keys.
- You will see the text starting with ssh-RSA in the Public key for pasting into OpenSSH authorized_keys file field which is located at the top of the window. Copy that entire text to your clipboard by pressing ctrl+c as you will require the key to paste on your clipboard in the public key tool of control panel or directly on the cloud server.
Various Ways to Use RSA Key Pair
RSA key pair generated through PuTTYgen is used in two various ways defined as below:
- To assign while creating a new cloud server
You can choose the public key from the given list of keys at the time of creating cloud server. If you don’t find your key in that list, then first add and then assign it. - Assign to an existing cloud server
At the time of connecting to the cloud server, first of all, you need to tell PuTTY to use it for utilizing your newly created RSA key pair.

Install Putty On Mac Catalina Free
- Keyfile – It is the name of the existing key file to read at the time of changing the current key.
- -t keytype – This command specifies the type of the key to creating. Its acceptable values are RSA and dsa.rsa1.
- -b bits – This command specifies a total number of bit in a particular key. 1024 is the perfect size for DSA key, while 2048 or 4096 are the perfect size for RSA keys.
- -q – This command suppresses the message about progress at the time of key generation.
- -C new-comment – This command is used to specify the comment to describe the key. It can be used for new and/or existing key. Key operation is not affected by comment. However, it is used to recognize the key owner, it’s not reliable completely as any value can be applied to it.
- –P – This command is used to update the passphrase of a key. Passphrase helps to encrypt the private key. As passphrase can’t be add or update on command line, it prompts a new passphrase tool to alter it.
- –old-passphrase-file – The old password of the key remains in this file. This is used when the key is protected by a passphrase.
- –new-passphrase file – This file entails the new passphrase of the key. This command comes in the action either at the time of generating new key or while applying –P command to change the passphrase.
- -O output-type – This command defines what to give in output. By default, the private key is the output.
